DESEMPENHO DE CORDEIROS MESTIÇOS DORPER MACHOS E FEMEAS, EM CREEP FEEDING RECEBENDO RAÇÃO PELETIZADA ATÉ A DESMAMA

Abstract

This study was conducted to evaluate the performance of crossbred Dorper lambs males and females, in creep feed fed pelleted diets at weaning. 33 male and female lambs (17 females and 16 males), originated from the crossing of a commercial herd females with the male Dorper breed were used . The system of creep feeding was performed in collective bay and kept until weaning (80 days). The experimental design was completely randomized. The collected data for each variable were subjected to analysis of variance where the comparison of means was performed by Tukey test (p < 0.05) through the statistical program ASSISTAT.O pelleted diets on the creep feeding system provided the weight lambs weaning of 19.9 kg assuming that they are children of crossbred sheep. In relation to the daily weight gain, the result obtained was 0.214 kg/day depending on the genetic mothers, but lower than recommended for this system termination.
