Abstract

The objective was to observe the zootechnical parameters of calves from primiparous and multiparous cows. The data analyzed in the present work were obtained from Nelore cattle herds of a private company located in the municipality of Cotegipe – BA. In the study, 620 calves, male Nellore, were daughters of primiparous and primiparous multiparous cows. The data collection period was divided into three periods and held during the months of October 2017 to September 2018. Therefore, there is a numerical difference between the variables birth weight, weaning weight and weight gain among the calves of the primiparous and multiparous cows. It was observed in this study and during the traineeship period, that the calves of early multiparous cows presented better performance in the breeding phase, while the primiparous calves had better performance in the rearing phase.
