The aim of this study was to evaluate the influence of body condition score (BCS) on reproductive performance of beef cows before and after calving and to evaluate the calving probability using body condition score and weight variation during critical periods of the cow reproductive cycle. From 2001 to 2005, the body condition score was recorded in 248 multiparous cows raised in native pastures, submitted to different supplementation treatments (mineral mixture only – control; dry supplement; liquid supplement and liquid […]

The present work was carried out with the objective to evaluate the effects of different energy levels offered in the final third of gestation on the ewe-lambs behavior of animals from the Morada Nova breed. The experiment was divided into three treatments – three groups of eight ewes, fed isoprotein diets containing different energy levels (2.0, 2.4, and 2.8 Mcal ME/kg DM), with eight replicates each. There was effect of the treatment on the maternal behavior evaluated variables (vocalization, act […]
