Description
Summary:The objetive of the present study was to determine the age of puberty through levels of progesterone [greater than or equal to] 1ng/ml, using a herd of 30 heifers buffalo in a pasture system, born and wean in 2014 and test in February and july of year 2015. The data registered was weight at birth (WB), weight at wean (WW), and weight at puberty (WP), daily gain preweaning (DGW pre), daily gain postweaning (DGW post). The blood was recovered from the jugular vein every 14 days to obtain serum for progesterone (P4) analysis by chemiluminescence. The puberal animals were divided every fifteen days according to their calving in: first (G1), second (G2), and third (G3). There were performed multiplemeasures using ANOVA, taking as a qualifying variable the calving through Duncan Test with an 5% [alpha]. The results for G1, G2 and G3 were WB 35.7([+ or -] 1.07), 37.6([+ or -] 1.11), 37.6([+ or -] 1.43) respectively (p>0.05); WW 233.6([+ or -] 6.44), 242.4([+ or -] 6.65), 207([+ or -] 8.68) only significative (p0.05). For the age the results were 450([+ or -] 14.9), 412([+ or -] 14.9), 378([+ or -] 18.7) being different G1 y G3 (p
