Abstract excerpt
This study investigated the phenotypic expression and genetic architecture of maturity, defined as the ability to maintain or increase milk yield across parities, in French Alpine and Saanen dairy goats. Maturity showed low heritability (∼0.10) and high repeatability (∼0.55) in both breeds and was genetically independent from milk yield routinely evaluated (parity 1 to 10) but positively correlated with milk...
