Genetic trend for milk and fat productions for Holstein Cattle in Minas Gerais State



Genetic trend for milk and fat productions for Holstein Cattle in Minas Gerais State



Revista Brasileira de Zootecnia 30(1): 66-70



The genetic trends for milk and fat yields of Holstein dairy cattle in Minas Gerais State, Brazil were estimated. The statistical analyses were made by means of mixed models, using restricted maximum likelihood and animal model. The fixed effects studied were herd-year-season at calving and linear and quadratic effect of age at calving besides the animal and residual random effects. The genetic trends were obtained by regression of the breeding value on the year of birth of the cows.
