RESUMO

The aim of this study was to analyze the influence of age, gender, pregnancy, puerperium, lactation and breeding systems in the constituents of lipid metabolism and glucose of buffaloes. The biochemical analysis was obtained by determining the levels of serum cholesterol, triglycerides, beta-hydroxybutyrate (ß-HBO), non-esterified fatty acids (NEFA) and plasma glucose levels. It was also meant to suggest reference values for these metabolites. Were used six properties of buffaloes Murrah, Mediterranean, and crossbreed, all located in the São Paulo state. Were collected 635 samples of serum and plasma between November 2009 and July 2010. To assess the condition of the general state of animals was used to evaluate body condition score (BCS) by assigning scores from 1 to 5 only for animals over 24 months. The values of the arithmetic mean, standard deviation, standard error means, coefficient of variation, confidence interval (95%), and minimum and maximum values were calculated using the Means procedure of SAS version 9.2. Tests for normality of residuals and homogeneity of variances were performed using the SAS Guide to Data Analysis. Data were analyzed by ANOVA using the SAS procedure Glimmix. The group information (Age, Pregnancy, Lactation, Gender, Puerperium; Creation System), Farm, Category, Number of Offspring and BCS, as well as their interactions, were used in statistical models. It was concluded that the metabolic components were significantly influenced by age, gender, postpartum, lactation and breeding system, and is not verified by the relevant influence pregnant heifers. Due to the large number of samples strategically taken, obtained from different stock breeding, were also suggest reference values for serum lipids and glucose of buffaloes in different ages, genders, moments of pregnancy, stages of peripartum and lactation periods.
