Perfil hematológico e bioquímico de Bubalinos (Bubalus bubalis) sadios da raça Murrah, criados em clima tropical

Abstract

The objective of this study was to determine blood component values of healthy buffaloes raised under tropical climate conditions, assessing the effect of age and sex development. Samples of 135 dairy-quality Murrah buffaloes from three farms located at Recôncavo Bahia were evaluated and distributed in nine age groups: G1 (0 to 15 days), G2 (over 15 to 30 days), G3 (over 30 up to 60 days), G4 (over 60 up to 120 days), G5 (over 120 up to 180 days), G6 (over 7 months up to 12 months), G7 (over 12 months up to 36 months), G8 (up 36 months to 60 months) and G9 (over 60 months), each with 15 animals. Group G1 to G6 included males and females and from G7 to G9 only females. For sex factor evaluation, two groups were formed with 39 male and 39 female animals up to one year old. Blood samples with anticoagulant were collected for blood count (erythrogram and leukogram) and samples without anticoagulant for biochemical analyzes (total proteins, albumin, globulin, A:G ratio, glucose, cholesterol, triglycerides, AST, GGT, calcium, phosphorus, magnesium and potassium). Data were subjected to statistical evaluation initially by performing the analysis of variance and then to compare the means between groups, Tukey test with significance level of 5% was applied. Age showed influence with all blood count components, except for the absolute value of monocytes, while most biochemical components showed influence with age, except phosphorus and potassium. Gender influenced total white blood cell count, absolute monocyte value, glucose, cholesterol and AST.
