Effects of sire genotype on lamb performance at weaning in extensive sheep systems

Animal, 2019
A low finishing weight and poor carcass characteristics are major causes of lower incomes in extensive sheep flocks; however, the use of terminal sire crossbreeding would improve lamb performance and carcass traits under these conditions. The aim of this
