Abstract excerpt
Developing traits that indirectly capture different stages of an animal’s reproductive life may support more effective selection for herd reproductive efficiency. This study aimed to estimate phenotypic and genetic parameters for lifetime offspring count (LOC) and age at first kidding (AFK) in Brazilian Saanen goats and to assess the goodness-of-fit of Gaussian, Poisson, and ordinal Bayesian mixed models for LOC....
