Genetic parameters for various semen production and quality traits and indicators of male and female reproductive performance in Nellore cattle.

ABSTRACT:

Background

Given the economic relevance of fertility and reproductive traits for the beef cattle industry, investigating their genetic background and developing effective breeding strategies are paramount. Considering their late and sex-dependent phenotypic expression, genomic information can contribute to speed up the rates of genetic progress per year. In this context, the main objectives of this study were to estimate variance components and genetic parameters, including heritability and genetic correlations, for fertility, female precocity, and semen production and quality (andrological attributes) traits in Nellore cattle incorporating genomic information.

Results

The heritability estimates of semen quality traits were low-to-moderate, while moderate-to-high estimates w
