          Abstract

          ABSTRACT: For the evaluation of serum biochemical parameters of Pêga breed donkeys (Equus asinus), for the different age groups and sex, blood samples of 123 animals were analyzed, of 29 males aged from 8 days to 10 years and of 94 females (15 lactating) aged from 2 days to 12 years, from two farms in the central-southern Minas Gerais, Brazil. The donkeys were divided by age into 5 groups: Group 1 (≤6 months), Group 2 (7-12 months), Group 3 (13-48 months), Group 4 (49-72 months), and Group 5 (≥73 months). According to the sex, they were divided into two groups, males and females. Serum biochemical elements: total protein, albumin, globulin, the A:G ratio, cholesterol, triglycerides, uric acid, creatinine, urea, phosphorus, calcium, Ca:P ratio, magnesium, alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), gamma glutamyl transferase (GGT) and creatine kinase (CK), were evaluated in all animals. No significant differences were found for globulins, uric acid, urea and A:G ratio between age groups. Group 4 showed the highest values for total protein when compared with animals in Group 1 and 2. In Goup 2, the donkeys showed albumin levels lower than Group 3 and 4. Group 1 they had cholesterol levels higher than those in Group 2 and 4, and similar of the other groups. Higher phosphorus serum concentration was observed in Group 1. Calcium was significantly lower in Group 2. The Ca:P ratio was higher for Group 5. The magnesium values were significantly higher in donkeys older than 49 months (Group 4 and 5). The value of AST was lower for group 1. The ALP enzyme was significantly higher in younger animals up to 12 months, followed by gradual decrease with advancing age. The values of GGT were higher in donkeys up to 6 months, followed by decreasing values for subsequent groups. No differences were found between genders for albumin, cholesterol, creatinine, urea, uric acid, Ca:P ratio, magnesium, ALT, AST, and alkaline phosphatase. Females had higher values for total protein, globulin and triglycerides. Males showed higher values for A:G ratio, phosphorus, calcium and CK. The results showed that age and sex can influence serum biochemical values of Pêga breed donkeys.

          RESUMO: Para a avaliação dos parâmetros bioquímicos séricos de jumentos (Equus asinus) da raça Pêga, quanto às diferentes faixas etárias e sexo, foram analisadas amostras sanguíneas de 123 animais, sendo 29 machos com idades de 8 dias a 10 anos e 94 fêmeas (15 lactantes) de 2 dias a 12 anos, de dois criatórios na região centro-sul do estado de Minas Gerais. Os animais foram divididos em 5 grupos de acordo com as idades: Grupo 1 (≤6 meses); Grupo 2 (7-12 meses); Grupo 3 (13-48 meses); Grupo 4 (49-72 meses) e Grupo 5 (≥73 meses). De acordo com o sexo, foram divididos em dois grupos, machos e fêmeas. Para todos os animais foram realizadas as análises de proteínas totais, albumina, globulinas, relação A:G, colesterol, triglicérides, ácido úrico, creatinina, ureia, fósforo, cálcio, relação Ca:P, magnésio, alanina aminotransferase (ALT), aspartato aminotransferase (AST), fosfatase alcalina (FAL), gama glutamiltransferase (GGT) e creatina quinase (CK). Não foram encontradas diferenças significativas para os elementos globulinas, ácido úrico, ureia e relação A:G entre as faixas etárias. O Grupo 4 apresentou os maiores valores para proteínas totais quando comparados aos animais dos grupos 1 e 2. Os animais do Grupo 2 mostraram valores de albumina inferiores aos Grupos 3 e 4. Os animais do Grupo 1 apresentaram valores de colesterol superiores aos do Grupo 2 e 4, e semelhante aos demais grupos. Maior concentração sérica de fósforo foi observada nos animais do grupo 1. O cálcio apresentou valor significativamente menor no Grupo 2. A relação Ca:P foi maior para o grupo 5. Os valores do magnésio foram estatisticamente superiores nos animais com idade superior a 49 meses (Grupos 4 e 5). O valor da AST foi menor para o Grupo 1.As enzimas FAL apresentaram valor significativamente maior nos animais mais jovens até 12 meses, seguida de redução gradual com o avançar da idade. Os valores da GGT foi maior nos jumentos com até seis meses de idade, seguido de valores decrescentes para os grupos subsequentes. Não foram encontradas diferenças entre os sexos para albumina, colesterol, creatinina, ureia, ácido úrico, relação Ca:P, magnésio, ALT, AST e fosfatase alcalina. As fêmeas tiveram valores maiores para proteínas totais, globulinas e triglicérides. Os machos mostraram maiores valores para relação A:G, fósforo, cálcio e CK. Pelos resultados nota-se que a idade e o sexo podem influenciar nos valores bioquímicos séricos dos jumentos da raça Pêga.

          Intolerance to hydrolysed cow's milk proteins in infants: clinical characteristics and dietary treatment.

          Multiple food intolerance in infants, including intolerance to extensively hydrolysed proteins (HP), is often difficult to treat. However, few data have been reported on clinical outcome and dietary treatment of these patients. To evaluate the clinical characteristics of patients with HP-intolerance and the long-term outcome of treatment with ass' milk. This study included 21 HP-intolerant infants (15 males, median age at diagnosis 2 months) treated with an ass' milk-based diet and 70 cow's milk (CM) intolerant infants (40 males, median age at diagnosis 3 months) treated with casein hydrolysate milk-based diet. All patients were followed-up for a median period of 4 years. Both HP-intolerance and intolerance to other foods were diagnosed according to the double-blind placebo-controlled procedure. Formal CM-challenges were conducted at yearly intervals until tolerance was demonstrated. At diagnosis and after one year of the respective diets, the following growth parameters were determined: relative weight for sex and age, relative weight for height and height z-score. During the study period, multiple food intolerance was documented in 21/21 HP-intolerant infants (ass' milk group) and in 20/70 infants with CM-intolerance but tolerating HP (casein hydrolysate group) (P < 0.0001). In the ass' milk group, the more frequent food intolerances were toward soya, oranges, tomatoes and fish; goat's milk intolerance was demonstrated in five out of six patients receiving this food, and sheep's milk derivatives intolerance in four out of seven; these patients tolerated ass' milk. During the study period 3/21 patients in the ass' milk group became ass' milk intolerant; they showed vomiting (one cases) or diarrhoea (two cases). A lower percentage (52%) of patients in the ass' milk group became CM-tolerant during the study period than in the casein hydrolysate group (78%) (P < 0.01) and the age of the children at CM-tolerance was higher in the ass' milk than in the casein hydrolysate-treated children (P < 0.05). At diagnosis, a higher frequency of cases with elevated serum total IgE and specific IgE to CM antigens (P < 0.01) was observed in the ass' milk group. No difference was recorded between the two treatment groups in any of the growth parameters considered either at diagnosis or during the follow-up. HP-intolerant patients showed a higher frequency of persistent food intolerance and of multiple food intolerance than patients tolerating casein hydrolysate. Ass' milk feeding was confirmed as a safe and valid treatment of the most complicated cases of multiple food intolerance.

            Blood analysis in newborn donkeys: hematology, biochemistry, and blood gases analysis.

            The knowledge of reference ranges for hematologic, biochemical, and blood gas parameters in the different species and the influence of breed and age on them is a fundamental tool for the clinician. For this reason, the aim of this study was to evaluate the age-related changes of hematologic and biochemical parameters in Martina Franca donkey foals during the first 3 weeks of life and of blood gases during the first 24 hours of age. Fifteen healthy donkey foals were enrolled; blood samples were collected from each foal at 10 minutes after birth, 1 hour after the first and second suckles, 12 and 24 hours after birth, daily from Day 2 to 7, and at Days 10, 14, and 21 of life. Erythrocytes, leukocytes, and platelets counts were assessed; also metabolic (alanine aminotransferase, aspartate aminotransferase, gamma glutamyl transferase, creatinphospokinase, lactate dehydrogenase, alkaline phosphatase, glucose, blood urea nitrogen, creatinine, total proteins, albumins, cholesterol, and total bilirubin) and electrolytic parameters (Ca, P, Mg, Na, K, and Cl) were evaluated. Finally, blood gases and metabolic parameters (pH, pCO2, pO2, sO2, TCO2, HCO3, lactate, and base excess) on venous blood were assessed with a portable analyzer. A statistical analysis to evaluate the influence of age and sex was performed. Several differences were found between sampling times, demonstrating that age influences these parameters. Moreover differences were found compared with data reported in literature for donkey foals of another species, horse foals, and adult donkeys. Although a great interindividual variation for some parameters exists, this study demonstrated that interval references should be addressed not only to different species, but also to specific breeds and to the neonatal period.

              Reference ranges and the influence of age and sex on hematologic and serum biochemical values in donkeys (Equus asinus).

              Hematologic and serum biochemical values were determined in blood samples from 217 donkeys (Equus asinus). Donkeys were classified on the basis of size, sex, age, and whether they were domestic or feral. Parametric (mean +/- 2 SD) and nonparametric (2.5th to 97.5th percentile) reference ranges were calculated for each analyte. For all donkeys, 26 of 46 analytes significantly departed from gaussian distribution. Serum lactate dehydrogenase activity in miniature donkeys was higher than that in other donkeys. Differential leukocyte counts in feral donkeys differed from those in other types in ways that suggested that the former had smaller parasite loads or experienced greater stress. Erythrocyte, lymphocyte, and platelet counts and fibrinogen, glucose, inorganic phosphorus, and potassium concentrations decreased with age. Eosinophil counts, mean corpuscular volume, and plasma protein, serum protein, and serum globulin concentrations increased with age. Female donkeys had significantly (P less than 0.05) higher mean corpuscular hemoglobin concentration and leukocyte and neutrophil counts than did male donkeys. Mean corpuscular hemoglobin increased with age, and females had higher values than did males of all age groups. An interaction between age and sex was observed for alkaline phosphatase activity, with a trend for decreased activity with age.
