ESTIMATION OF PARAMETERS AND GENETIC TRENDS FOR MILK PRODUCTION IN BUFFALOES Murrah USING BAYESIAN INFERENCE
Abstract
The goal is to estimate the parameters and evaluate the genetic trend for milk production in Murrah buffalo born in the period 1975 to 2001 parameters and breeding values were estimated by Bayesian inference using Gibbs sampling. Genetic trends were obtained by regression of breeding values on the first year of production of the female. Heritability and repeatability estimates were equal to 0.39 and 0.48, respectively. The genetic trend was equal to -3.62 kg / year. Despite the high genetic variability present in the population, this has been misused in the process of selection of animals in herds evaluated.Downloads
