Abstract: The aim of study was to estimate the genetic and phenotypic parameters and the evaluate the genetic trend of milk yield of parameters by using 417 Saanen goats from herds enrolled in PROCAPRI program. The variance component estimates were obtained by the Restricted Maximum Likelihood method, using an animal model. Heritability and repeatability estimates were 0.38. The results indicated that selection could be used to improve my and repeated measures of my are needed before deciding whether to cull a goat. |
