Synergy between selection for production and longevity and the use of extended lactation: insights from a resource allocation model in a dairy goat herd.

Abstract excerpt

Although most of the genetic progress in production efficiency is achieved through selection at a global scale, locally, farm managers can also influence the selection process to better match genotypes and their varying herd environment. This study focused on the influence of a particular management decision--the use of extended lactation (EL) in dairy goat production systems--as it affects the survival and...
