Growth, health and blood glucose concentrations of calves fed high-glucose or high-fat milk replacers. Considerations about the prophylapsis of the uterine and vaginal prolapse in Italian Mediterranean buffalo cows. The lactation curve in dairy species can be seen as the graphical representation of milk yield during the time. There are many factors which affected the lactation curve in dairy species: breed, genetic basis, season and period of calving, age at calving, environmental factor and health status (specially on mammary gland). The typical shape of lactation curve has two characteristic parts: a rapid increase from calving to a peak period in early stage of lactation and a gradual decline from peak of yield to the end of lactation (Leon-Velarde et al. The most important phase is the persistency of the lactation: persistency of milk production is the ability of animal to maintain milk production at high level after peak production, or usually refers to the rate of decline in daily yield after the peak of lactation (Togashi and Lin, 2004). Random regression model was applied for the analysis of test day record and to study the genetic persistency of the first lactation milk yield of Indian Murrah buffaloes (Geetha et al. In figure 1 the lactation curves after the first, the second and the third calving are reported. The average production was 2 160 kg in the first lactation, 2 348 in the second lactation and 2 356 in the third one. Is clear that the buffalo potential production is observed in the second lactation (Coletta and Caso, 2008). Effect of parity on lactation curve in Mediterranean Italian breed (Coletta and Caso, 2008). The effect of age and calving season on lactation curves in Mediterranean Italian buffaloes was demonstrated too by Catillo et al. Effect of parity on lactation curve in Mediterranean Italian breed (Catillo et al. Lactation curves were different for the first and later parities with lactations of different duration also in Nili-Ravi buffaloes (Khan and Chaudry, 2000), who found a lactation length of about 289 days for an average milk yield of 1 984 kg as about 59% of the lactations had length shorter than the standard lactation of a 10 months. The same Authors found different lactation curves according the parities (figure 3, Khan and Chaudhry, 2001). These Authors found 10% of atypical lactations, with the first calves having the highest frequency. In the latest age at calving the relative decline from second to third months is twice faster as compared with the earliest class. Different lactation curve in the cases of early and late calving for the Murrah Bulgarian buffalo cow (Penchev et al. Milk production and milk flow profiles are important parameters to be recorded and evaluated. Milk flow curves have been well studied in the cattle (Weis et al, 2004; Bruckmaier, 2005; Tancin et al, 2006), partially in sheep and goat (Dzidic et al. The graphic representation of milk flow curve can be showed by different phases: the first is the increasing phase (milk letdown time and incline time), represented by the time elapsed between the attachment of the milking clusters and the time until constant milk flow; the second is the plateau with a constant milk flow (peak of milk flow is generally in this phase); the third is the decreasing phase and represents the time from the plateau phase until the detachment of the milking cluster at stop of milk flow; an eventual fourth phase may be the stripping yield, preceded by blind phase. They are typical and characteristic for each dairy species: cattle, buffalo, goat and donkey (see fig 5, 6, 7, 8). Specifically, milk flow curves and other parameters are influenced by anatomical (Thomas et al, 2004; Ambord et al. In a recent trial, we verified that the manual stimulation at different times provoked the increasing of released oxytocin and of the intra-mammary pressure and finally the increasing of cisternal teat largeness and the reduction of teat canal length (Borghese, 2012, figure 9 and 10). Ultrasound cross section of fore teat before (left) and after (right) about 90 seconds of manual stimulation. The cisternal milk fraction is immediately available while the alveolar fraction needs an oxytocin stimulation to release. In Mediterranean Italian buffaloes it have been observed a higher cisternal fraction of total milk than in Murrah breed (respectively 7. In buffalo management, the milking room and the milking machine are really a critical point and the characteristics of milking vacuum and milking pulsations are strictly connected with milk flow observations (Pazzona, 1989; Dogra et al. Animal general health, with particular regard to mastitis, influences milk composition and milk flow parameters. In buffalo, Somatic Cell Count is a good indicator of subclinical mastitis (Pyorala, 2003; Thomas et al. These differences characterize the milk flow curves in buffalo species and result in different relieved parameters as the total milking time and milk yield. Bimodal curve (with cisternal fraction) in a high producing buffalo (Borghese et al 2007 b) Figure 13. Slow milk ejection with a long plateau time caused by a tight teat canal 221 Figure 14. Figure 11 shows a normal milk flow curve, but from a farm where over-milking was applied often. Visualisation of the long phase of over-milking must oblige the milkers to change the milking routine and to solve this problem, applying the automatic detachment. Milking of the cisternal fraction is shown as the first curve in figure 12 and known as a bimodal curve, which is not frequent in buffaloes, because of the small proportion of the cisternal fraction. Figure 13 is a curve from a buffalo with very low flow rate probably due to a tight teat canal, which is seen frequently in Italian buffalo herds. Most buffaloes need at minimum 8 minutes of milking time, but exceptions can be seen for buffaloes with a high peak flow rate and a short plateau time (Figure 14). Figure 15 showed a milk flow curve with a double profile, due to the partially milk emission disturbed or due to the repositioning of milking cluster. Figure 16 is a milk flow curve of a buffalo not responding to stimulation during teat preparation until oxytocin was injected. The first is classified as failure (no attachment of cluster), the second as incomplete (partially attachment of cluster only two quarters) and the third as complete one, perfectly attachment of cluster (figure 19) (Boselli et al. In figures 20 and 21 milk flow curves at quarter level are shown (Borghese, 2012). Time until a milk flow of 500 g was 195 versus 329 sec in the morning and 224 versus 383 s. Electrical conductivity can be measured simultaneously with the milk flow using the Lactocorder. General udder health and particular teat pathologies may influence milk production in quantity, quality and milk ejection parameters. The general health of animals and good livestock conditions are very important in milk production. Moreover, the milking machine is a very critical factor for the milk flow rates because of the characteristics of milking vacuum, milking pulsation and pulsation frequency, and other technical characteristics connected to the milking equipment (Pazzona, 1989; Dogra et al. Caria et al (2011) compared the effects of milking at low vacuum (36 kPa) and medium vacuum (42 kPa) on milk emission characteristics and milking system performances. The results showed that the low vacuum level did not influence both milk yield and milk ejection time. Milk yield was not influenced by the working vacuum level and resulted satisfactory also at lower levels; the vacuum levels of 37 and 40 kPa showed the best milkability conditions, at which plateau phase was longer than decline phase and lag time was not affected by vacuum level. These results suggest to apply a premilking udder stimulation to reduce milk let-down time increasing the average milk flow and reducing total milking time.

In general, categories in this chapter include the less well-defined conditions and symptoms that, without the necessary study of the case to establish a final diagnosis, point perhaps equally to two or more diseases or to two or more systems of the body. Practically all categories in the chapter could be designated "not otherwise specified", "unknown etiology" or "transient". The Alphabetical Index should be consulted to determine which symptoms and signs are to be allocated here and which to other chapters. The category is for use in multiple coding to identify this condition resulting from any cause. Where multiple sites of injury are specified in the titles, the word "with" indicates involvement of both sites, and the word "and" indicates involvement of either or both sites. The principle of multiple coding of injuries should be followed wherever possible. Combination categories for multiple injuries is provided for use when there are insufficient detail as to the nature of the individual conditions, or for primary tabulation purposes when it is more convenient to record single code; otherwise, the component injuries should be coded separately.

Immunologic memory is the rapid and specific viral immune response programmed by previous virus infection or immunization gastritis symptoms empty stomach order nexium 40 mg online. Thus, vaccines prime the immune system and program it to anticipate and resist future infection by that specific pathogen. To provide a robust immune response and subsequent immune memory that prevents or at least controls infection, three approaches have been used for developing successful vaccines. The first and overall the most successful is to use an attenuated or weakened virus whose composition closely resembles that of the virus to be overcome. A second way is to use a killed virus preparation as is done for the Salk poliomyelitis vaccine. A third method utilizes recombinant viral protein(s), that is, a subunit vaccine, and is represented by the one that successfully prevents hepatitis B virus infection. This is an irreversible process that occurs immediately after infection and lasts until the cell in which integration takes place is eliminated. This reservoir is stable over the life of the infected individual, is immunologically silent, and, if the cell becomes activated, it can produce new infectious viruses. The discovery that a viral infection can have links with a cancer has 260 Viruses, Plagues, and History a long history. Nearly 100 years ago, the search for a viral source of cancer began, and for the past forty-five years the focus has been on a specific viral group, the human retrovirus. Scientists now know that viral infections cause at least 20 percent of all cancers. Papillomaviruses were among the first viruses defined as filterable agents (40) and shown by Harold zur Hausen and colleagues in the late 1970s (41) to be associated with human epithelial cancers including human cervical cancer. For this observation and subsequent follow-ups, zur Hausen was awarded the Nobel prize in Physiology and Medicine for 2008. Further, over onequarter of the six hundred-plus known animal viruses have oncogenic potential, that is, the capacity to initiate in animals or cultured cells the kind of cellular division and growth that promotes the development of tumors. Transmission of cancers among animals had been attributed to viruses since the early part of the twentieth century. Many of these cancers arose from retroviruses, a family of viruses in which the replication of the viral nucleic acid is unique. At the close of the nineteenth century, the first virus that infected animals had been reported by Froesch and Loeffier (44). By the first decade of the twentieth century, viruses were being isolated and manipulated as physical entities through the use of Pasteur-Chamberland-Berkefeld filters and experimental animals. It was during this time that the first retroviruses were shown to be transmissible agents that could cause cancers. Vilhelm Ellermann and Oluf Bang (45), working in Copenhagen, Denmark, described the first true cell-free transmission of cancer. However, at that time leukemia was not considered a cancer, and so this discovery lacked impact. Three years passed and then Peyton Rous reproduced solid tumors (sarcomas) in fowl by injecting them with filtrates of a tumor obtained from a hen. Working at the Rockefeller Institute, Rous, after examining Plymouth Rock hens brought to him by farmers, identified their malignant tumors as spindle cell sarcomas (46). He then demonstrated that these tumors could be transmitted to closely related animals. He prepared a cell-free, bacteriafree filtrate of such tumors and inoculated it into a healthy chicken; as a result an identical sarcoma grew in that second chicken (46). Active research on breast cancers transmitted from the mother to her offspring via breast milk focused on determining whether the cancer came from a virus as opposed to a milk factor. The research results showed conclusively that the cancer originated from a retrovirus, later called mammary tumor virus. Despite these accumulated findings that associated cancer with viruses, the investigations failed to achieve major scientific recognition. The present evidence tends to indicate that 262 Viruses, Plagues, and History the same may be true of viruses. As causes of the continuation of the malignant process, many microorganisms which may have been described as specific etiologic agents may be disregarded. In spite of this advice, fifty years later the first human retroviruses were isolated by workers at the National Cancer Institute and shown to cause cancers (48,49). From the 1950s through the 1970s, a plethora of discoveries were made regarding retroviruses. Many could cause tumors in mammals, and these could be transmitted vertically (into the fetus) as well as horizontally (from one individual to another after birth). Such infections often harm the immune system, most frequently by immunosuppression (suppressing its function). For example, a number of retroviruses can live in lymphocytes and macrophages and stop their activity as members of the immune system. A critically important development was a test to detect reverse transcription and to identify retroviruses, thus facilitating the study of retroviral infections. The 1970s ushered in frantic activity in a large number of laboratories housing the search for a retrovirus that could infect humans. Although many candidates were found, careful investigation showed that these retroviruses were not of human origin but rather were contaminants of nonhuman retroviruses. The most common examples were retroviruses that contaminated cells originally from subhuman primates or other mammals and later used for culturing human materials. However, as we will see, others have also played roles in establishing the importance of retroviral infections. Montagnier received the 2008 Nobel Prize in Medicine along with Francoise Barre-Sinoussi for this work but, quite depressing, Bob Gallo was left out. Initially, he trained in virology at the National Institutes of Health, where he became immersed in the study of retroviruses. As a result, his work joined together the fields of retrovirology and blood cell biology. This, combined with 264 Viruses, Plagues, and History a technique to detect viral reverse transcriptase developed by Howard Temin and David Baltimore, for which they shared a Nobel Prize in 1975, positioned Gallo to look for human retroviruses. First, tests had to be perfected that distinguished viral reverse transcriptase from cellular reverse transcriptase. Independently, investigators from Japan isolated a similar virus causing acute adult T-cell leukemia (52). The isolation of these first human retroviruses was made possible by finding reverse transcriptase activity in the fiuid of cultured T cells taken from patients with leukemia. Under an electron microscope, the virus looked like a C-shaped particle, just like retroviruses found previously in nonhuman mammals. The genes of this virus were mapped and their relative positions to each other in the genome determined. A nodule which had not been present on previous examination was noted on the left wall of the chest. Clearly a new and dangerous disease had emerged not only in the United States but also in Europe and Haiti. Although the causative agent was not known, epidemiologic evidence suggested an infectious one, probably a virus. The history of other infectious agents that have caused epidemics in the past indicates that they frequently accompany major changes in social and/or economic conditions.

In single-meal studies gastritis diet soda buy nexium 20 mg low price, high palatability was also associated with increased food consumption (Bobroff and Kissileff, 1986; Price and Grinker, 1973; Yeomans et al. These results suggest that high energy-dense foods may be overeaten because of effects related to their high palatability. The third mechanism is that energy-dense foods reduce the rate of gastric emptying (Calbet and MacLean, 1997; Wisen et al. This reduction, however, does not occur proportionally to the increase in energy density. Although energy-dense foods reduce the rate at which food leaves the stomach, they actually increase the rate at which energy leaves the stomach. Thus, because energy-containing nutrients are digested more quickly, nutrient levels in the blood fall quicker and hunger returns (Friedman, 1995). While a subjective measure, highly palatable meals have also been shown to produce an increased glycemic response compared with less palatable meals that contain the same food items that are combined in different ways (Sawaya et al. This suggests a generalized link among palatability, gastric emptying, and glycemic response in the underlying mechanisms determining the effects of energy density on energy regulation. Researchers have used instruments such as visual analogue scales to measure differences in appetite sensations. A number of studies have been conducted in which preloads of differing energy density were given and hunger and satiety were measured either at the subsequent meal or for the remainder of the day. In the studies that administered preloads that had constant volume but different energy content (energy density was altered by changing dietary fat content), there was no consistent difference in subsequent satiety or hunger between the various test meals (Durrant and Royston, 1979; Green et al. However, in those studies using isoenergetic preloads that differed in volume (energy density was altered by changing dietary fat content), there was consistently increased satiety and reduced hunger after consumption of the low energy-dense preload meals. It has been reported, however, that diets low in fat and high in carbohydrate may lead to more rapid return of hunger and increased snacking between meals (Ludwig et al. Because individuals were blinded to the dietary content of the treatment diets, the results from these studies demonstrate the shortterm effects of energy density after controlling for cognitive influences on food intake. It is important that cognitive factors are taken into account during the interpretation of results of preload studies. When individuals were aware of dietary changes, they generally (Ogden and Wardle, 1990; Shide and Rolls, 1995; Wooley, 1972), but not always (Mattes, 1990; Rolls et al. In well-controlled, short-term intervention studies lasting several days or more, high fat diets were consistently associated with higher spontaneous energy intake (Lawton et al. From shortand longer-term studies, volunteers consistently consumed less dietary energy on low fat, low energy dense diets compared to high energy-dense diets (Glueck et al. The extent to which energy intake was reduced on low energy-dense diets was similar for shortand long-term studies. An alternative way to study the effects of energy density on energy intake in short-term studies has been to compare energy intake between diets of similar energy density that differ in dietary fat content. Using this approach, when fat content was covertly varied between 20 and 60 percent of energy, there was no significant difference in energy intake between groups (Saltzman et al. These results suggest that energy density plays a more significant role than fat per se in the short-term regulation of food intake. During overfeeding, fat may be slightly more efficiently used than carbohydrate (Horton et al. Thus, high fat diets are not intrinsically fattening, calorie for calorie, and will not lead to obesity unless excess total energy is consumed. It is apparent, however, that with the consumption of high fat diets by the free-living population, energy intake does increase, therefore predisposing to increased weight gain and obesity if activity level is not adjusted accordingly (see Table 11-1). While many of the short-term studies showed a more dramatic effect on weight reduction with reduced fat intake, the long-term studies showed weight loss as well. However, a number of shortterm studies suggest mechanisms whereby high fat intake could promote weight gain in the long-term. In addition, shortand long-term intervention studies provide evidence that reduced fat intake is accompanied by reduced energy intake and therefore moderate weight reduction or prevention of weight gain. For these reasons, it may be concluded that higher fat intakes are accompanied with increased energy intake and therefore increased risk for weight gain in populations that are already disposed to overweight and obesity, such as that of North America. However, this conclusion must be drawn with caution when it is applied to societies in which dietary and exercise habits differ markedly from societies in rural Asia and Africa. For this reason, the effects of low fat diets must be viewed in the context of current societal habits in the United States and Canada and of changing habits in developing countries. It has been postulated that a high fat intake predisposes to a prothrombotic state, which contributes to venous thrombosis, coronary thrombosis, or thrombotic strokes (Barinagarrementeria et al. When fat is consumed in typical foods it contains a mixture of saturated, polyunsaturated, and monounsaturated fatty acids. Even when the content of saturated fatty acids in consumed fats is relatively low, the intakes of these fatty acids can be high with high fat intakes. For example, if all of the dietary fats consumed were low in saturated fatty acids. Consumption of a variety of dietary fats would likely result in an even higher percentage of saturated fatty acids. Thus, in practical terms, it would be difficult to avoid high intakes of saturated fatty acids for most persons if total fat intakes exceeded 35 percent of total energy. This fact is revealed by attempts to create a variety of heart-healthy menus (National Cholesterol Education Program, 2001). A prothrombotic state is characterized by elevations of plasminogen activator inhibitor and high fibrinogen concentrations, whereas a proinflammatory state is indicated by high c-reactive protein concentrations and other inflammatory markers. An excess of intra-abdominal fat has been identified as being highly associated with the lipid risk factors of the metabolic syndrome (Despres, 1993), although total abdominal fat appears to be even more highly predictive of the insulin resistance component of the syndrome (Abate et al. Thus, both obesity and weight gain are undisputed as major risk factors for the development of type 2 diabetes (defined as fasting plasma glucose fi 7 mmol/L) (American Diabetes Association, 2001). The contribution of diet per se to the development of type 2 diabetes is less clear. An important question is whether humans are similarly susceptible to this phenomenon independent of the effects of total fat intake on body fat content. Thus, if higher intakes of total fat lead to obesity, this in and of itself will reduce insulin sensitivity and predispose to the metabolic syndrome and type 2 diabetes. Recent studies have demonstrated that reduced fat intake and weight loss result in improved glucose tolerance and reduced risk of type 2 diabetes (Swinburn et al. In several population studies, investigators have attempted to determine the contribution of total fat intake to either insulin sensitivity or diabetes. These analyses are difficult to interpret because of the multiplicity of potential confounding variables. Nevertheless, several studies have reported an association between higher fat intakes and insulin resistance as indicated by high fasting insulin concentration, impaired glucose tolerance, or impaired insulin sensitivity (Lovejoy and DiGirolamo, 1992; Marshall et al. In the Insulin Resistance Atherosclerosis Study, total fat intake univariately correlated with less insulin sensitivity (Mayer-Davis et al. Lovejoy and DiGirolamo (1992) likewise found intercorrelations among insulin resistance, total fat intake, and obesity. In contrast, Larsson and coworkers (1999) found no evidence of independent effects of diet on insulin secretory or sensitivity among 74 postmenopausal women. Although several studies suggest an association between total fat intake and the presence of insulin resistance (Lovejoy, 1999; Vessby, 2000), the degree to which the relationship is mediated by obesity remains uncertain. Decreased physical activity is also a significant predictor of higher postprandial insulin concentrations and may confound some studies (Feskens et al. A number of metabolic and intervention studies have examined the relationships among fat intake, fasting glucose and insulin concentrations, areas under curves for plasma glucose and insulin concentrations, insulin sensitivity, glucose effectiveness, and glucose disposal rates (Table 11-8). Several studies reported that diets containing 35 percent fat were accompanied by more impaired glucose tolerance than diets containing 25 percent fat or less (Fukagawa et al. Coulston and coworkers (1983) found that a diet containing 41 percent fat led to significantly higher concentrations of insulin in response to meals compared with a diet containing 21 percent fat, but there were no alterations in fasting concentrations. In other studies, no effect on measures of glucose tolerance were reported when diets varied in fat content from 11 to 30 (Leclerc et al. When the diet was high in fat (50 percent of energy), the area under the curve for plasma glucose and insulin concentration was lower than when the diet had a low fat content (25 percent of energy) (Yost et al. Garg and coworkers (1992b) reported that insulin sensitivity, indicated by insulin-mediated glucose disposal, was similar after almost a month of ingestion of either a reduced fat (25 percent of energy) or an increased fat diet (50 percent of energy). However, favorable effects of substituting a monounsaturated fat diet for a saturated fat diet on insulin sensitivity were seen at a total fat intake of up to 37 percent of energy (Vessby et al.

He writes: 97 It is possible to conceive of a science which studies the role of signs as part of social life gastritis information order nexium 40 mg on-line. First and foremost we look upon colour as a visual phenomenon, and that includes a pictorial aspect. A first sign in this matter represents the return from the market with fresh products in the used string bag. This sign stands in a relation of redundancy with the connoted sign of the linguistic message (the Italian assonance of the name Panzani) [p. Consequently the linguistic sign links a sound pattern (the signifier) to a concept (the signified). And all of them, from the carefully chosen victuals to the tricoloured ensign, connect with Italy. We may notice that Barthes in his essay makes use of the terms denotation and connotation (actually picked up from the Scandinavian 20th century linguist Louis Hjelmslev, founder of the Copenhagen school of linguistics). The second term (connotation) refers to socio-cultural and personal meanings awoken by the picture or the text examined. In his last book Camera Lucida: Reflections on Photography (1980), Barthes returns to the photographic image. This time he analyses, in a more lyrical and less theoretical way, a number of classical black and white photographs. In this detailed and systematic study of the modes and codes of fashion, colour is surprisingly absent. Certainly, Barthes refers to a few expressions from selected fashion advertisements, used as mottos to the chapters of his book. This work contains a semiotic theory of aesthetic knowledge, including clarifying distinctions concerning colour. In a chapter dealing with the everlasting semiotic notion of reference, in his book Of Minds and Other Matters (1984), Goodman writes: Metaphor arises by transferring a schema of labels for sorting a given realm to the sorting of another realm (or the same realm in a different way) under the guidance or influence or suggestion of the earlier sorting. In exchange of the order of connotations he launches an aesthetic attitude of action. The following program is stated in the final chapter in Languages of Art: It involves making delicate discriminations and discerning subtle relationships, identifying symbol systems and characters within these systems and what these characters denote and exemplify, interpreting works and reorganizing the world in terms of works and works in terms of the world. Accordingly, a concept is transferred by a metaphor from a certain field to a new province. Let us now observe how Goodman deals with a blue picture, in which the literal and metaphorical applications are closer, almost convergent. A schema of color-predicates is carried first over to feelings and than back to colored objects. From this dichotomy originate the positive warm colours expressing warm feelings and the negative cold colours expressing downhearted feelings of chill, to give a simplified picture of this symbolic use of a pair of primary colours. In this oil on canvas the artist experiments by using the warm and cold colours in inverted order. The beholders feel the coolness of the red-painted room, while looking through the open door in the picture, at the vibrating summer heat from the greenery, and sense the lukewarm blue water in the garden-pond. When a colour is transferred from a realm to another its referential properties are changed. The American philosopher teaches us that it is not sufficient only to look at something. The consideration about actual fashion colour processes and planning implies some more questions: why also in production and in consume some colours are chosen instead of othersfi

Similar results were obtained in lactating buffalo cows when given access to an outdoor yard provided with pool (Terzano et al gastritis zeludac buy nexium 40mg lowest price. Recent studies also evidenced a positive effect on milk production (De Rosa et al. Machine milking impact on buffaloes welfare has been evaluated through the observation of behaviours considered as indicators of acute stress and their correlation with oxytocin administration (Cavallina et al. Buffalo welfare has been related to products quality in a European research project (De Rosa et al. Among welfare indicators, very important are the direct ones, relieved directly on animals, as the behavioural and the physiological. Particular remark has to be given to immunological and pathological parameters since disease is the higher expression of distress. Immunological indicators are reliable as they are not influenced by sampling methods and they are useful as deeply involved in pathology prognosis (Fagiolo et al. Generally, welfare problems can be managed only thanks to good management practices. Management is represented by a wide array of practices including breeding, feeding and nutrition, sanitation, exercise, disease diagnosis and prevention (Sharma et al. In buffaloes, conditioned pathologies are mainly represented by increased calves morbidity and mortality due to diarrhoea (nutrition or hygiene deficiencies) or to inflammation and injuries at prepuce, teats or navel, subsequent to cross sucking (poor environments and milk provided few times per day). Consequently mother and young relationships are closely bonded and the buffalo usually becomes more stressed when separated from the dam than the calves of cattle. Because of their intelligence and social habits 287 stress can be alleviated by keeping them in groups of five or more animals together with an older domesticated animal. In adult buffaloes, conditioned pathologies can be represented by an increase in vaginal and uterine prolapses that seems to be associated to unbalanced feeding during the dry period and could be also predisposed by the nutritional management during the first months of life. Metabolic diseases, so common in milk bovines, are rarely seen in buffaloes that show more commonly a reduction in fertility. Foot problems rarely cause lameness in buffaloes but claw overgrowth and corkscrew can be observed. Skin lesions and injuries to the udder due to the presence of horns, are more frequent in the primiparous. Machine milking, apart for injuries due to structural deficiencies, can finally cause the presence on animals of iatrogenic abscesses consequent to oxytocin injections. Farmers should be aware of the importance of management and stockmanship as means to control animal welfare and health. Glucose In all species glucose is used by various tissues and organs for free energy production. Blood glucose levels depend on the nutritive values of the diets, on social or environmental stress conditions as well as on physiological phases. It is well known that early lactation is characterized by a negative energetic balance, less intense in buffalo than in bovines: plasma glucose concentrations are lower during the catabolic phase of lactation, and are higher during the anabolic phase of lactation when energy intake is equal or superior to the energy release (De Rosa et al. Several researches on buffaloes during the dry milk period and lactation indicated that, among energetic metabolism indicators, serum glucose levels were very constant (Bertoni et al. Triglycerides the values of serum triglycerides are usually considered as indicators of good nutrition, increasing with high-fat diets (Bertoni, 1989), in the presence of an altered regulatory mechanism of the lipid metabolism or due to degenerated hepatic function. Buffalo cows show higher triglycerides 288 values during pregnancy (Zicarelli et al. Serum triglycerides concentrations increase during lactation and show a positive correlation with milk fat levels (Zicarelli, 1986). However, serum triglycerides increase in buffaloes under different environmental conditions (low temperatures and season) (Satriani et al. Buffalo cows in early lactation have higher energy requirements that cannot be supported by dietary intake. The higher concentration of cholesterol with the advancement of age is probably a physiological adjustment to meet growth requirements. The cholesterol decline in buffaloes under heat could be related with the decreased feed intake in hot environment (Gudev et al. Under normal physiological conditions, the production of ketone bodies occurs at a relatively low rate whereas if the concentration of ketone bodies exceeds in blood the result is an excessive metabolic acidosis. Blood acidification is dangerous, chiefly as it impairs the ability of hemoglobin to bind oxygen. Beta-hydroxybutyrate is stable, and it is usually present in higher concentrations than the 289 other ketones, it is a more sensitive test to use when monitoring for ketoacidosis and it is stable in whole blood for up to 48 hours at room temperature. However, environmental factors such as pollution, radiation and herbicides can also spawn free radicals. Antioxidants are molecules which can safely interact with free radicals and terminate the chain reaction before vital molecules are damaged. The principal micronutrient antioxidants are vitamin E, beta-carotene, and vitamin C. Additionally, these mechanisms depend on the nutritional status of antioxidant minerals, especially copper, zinc, iron, selenium, silicon, and manganese. The nutritional status of cattle in different regions of the world is often characterised by a lack of these minerals; therefore, there is a great potential for changes in the activity of defence mechanisms against free radicals (Kleczkowski et al. These micronutrients must be supplied in the diet as, in buffaloes, vitamin A, beta-carotene and selenium proved to enhance in vitro phagocytic and kill activities of polymorphonuclear leukocytes isolated around parturition (Ramadan et al. Normally, those mechanisms allow the body to handle free radicals, but if antioxidants are unavailable, or if the free-radical production becomes excessive, damage can occur. New and reoccurring metabolic and infectious diseases of cattle emerge when there is a disproportion in the balance between reactive oxygen species and the antioxidative enzymatic barrier (Kleczkowski et al. When the protein level of the diets is high, animals enhance gluconeogenesis by amino acids from protein degradation; on the contrary, when the protein level of the diets is low, animals reduce production (meat and milk) and afterwards enhance hepatic protein synthesis and the production of microbial protein. Heat exposure cause plasma total protein firstly to increase then decreasing, as a consequence of the initial haemoconcentration followed by haemodilution (Gudev et al. Urea the concentration of urea in the blood reflects the degree of protein catabolism. The values of serum blood urea are considered to be an indicator of total protein intake and its determination with creatinine is important in order to exclude renal damage. Serum blood urea levels are influenced not only by renal function but also by external factors. In fact, when the protein level of diets is excessive or when the energy/protein ratio is very low an insufficient ruminal protein synthesis follows; a high quantity of ammonia is formed and absorbed through the ruminal wall into the portal blood and is converted to urea in the liver. This, in the long run, may cause hepatic failure and degeneration causing infertility, mastitis, puerperal collapse, lameness and steatosis. When the scarcity of protein is heavy and lengthened, the protein synthesis is reduced and changes in haematochemical parameters and in productive and/or reproductive functions follow. The values of serum urea are also considered as indicators of stress conditions as they rise after a too high protein degradation under the stimulus of adrenalin and cortisol hormones (Maianti et al. In buffaloes serum urea levels rise during lactation, whether by high protein intake or by tissue protein mobilization. Furthermore, it would seem relevant to evaluate the protein/energy ratio in order to obtain a correct diet. In buffalo such a ratio can be increased: diets with a high protein concentration, in fact, determine less harmful effects in buffalo compared to that in bovine milk cows. Buffalo cows make better use of ingested nitrogen than bovine cows, even if there is a carbohydrate deficit, since buffalo ruminal milieu is more favourable to the growth of microrganisms using non proteic nitrogen (Langer et al. Enhanced urea level in hot conditions could be due to negative effects on rumen activity (Gudev et al. It also can be referred to muscular cells damage and tissue changes related to the neonatal phase in buffalo calves (Campanile et al. In buffalo heifers near to puberty, values of 216 U/l have been found (Borghese, 1994). It is an important index in liver diseases as it is 292 the first serum enzyme that increases even in mild liver disease. Higher-than-normal levels may indicate: intestinal ischemia (blood deficiency) and infarction (tissue death); liver disease (for example, hepatitis); muscle injury; muscular dystrophy; neoplastic (new abnormal tissue formation) states; pancreatitis; pulmonary infarction (tissue death); heart attack; hemolytic anaemia; hypertension. Alkaline phosphatase is released into the blood during injury and during such normal activities as bone growth and pregnancy. However, higher values are found in buffaloes during the first 40 days of life due to the more intense bone remodelling.
