Partition of genetic trend for milk yield by gender and flock in Pag sheep
Breeding programs for dairy sheep seek to improve a set of economically and/or functionally important traits. Their success is measured by genetic trends, and their partitioning allows the contributions of different selection pathways to be quantified. This study aimed to estimate the genetic trend for daily milk yield in Pag sheep and to partition it by gender and flock. The estimated genetic gain was ~1 kg per production year (120 days). Females contributed to selection gain much more than males, while the within-flock contribution varied over the years, making it difficult to rank their contribution in the overall gain. The results imply that rams should be selected more carefully, preferably based on estimated breeding values.
