Performance of the beef cattle in Alagoas state
Abstract
This work was conducted to evaluate the performance of calves Nellore and cross and to study the influence of the fixed effects on performance of these animals in the State of Alagoas. The traits were studied weight at birth (WB), the weaning weight (WW), daily weight gain of birth to weaning (GBW). Three models were employed for to study WB. The first model included the effects of farm, genotype, sex, year and month of birth nestled into the year and sex and genotype interaction. The second model included the effects of genotype, sex and month of birth and sex and genotype interaction. And third, the effects of farm, sex, year and month nestled into year. The WW and GBW was evaluated the effects of months of weaning, sex, genotype, sex and genotype interaction and the weaning age covariable. All statistical analysis of this work was made using the procedure GLM of SAS ®. Animals cross ½ Nellore + ½ Blonde and the “three cross” were higher for the WB on the other, indicating additive and non-additive effects. Genotype “three cross” were higher for WW. The crossing animals were higher than Nellore for GBW.Downloads
