Modern maternal-line genotypes have impressive farrowing performance, increasing litter size by approximately 0.33 pigs per litter per year since 2006 (Tokach et al., 2019). One of the keys to continually improve litter size is genetic improvement through gilt introductions. However, deficient management strategies in gilt development spanning from the gilt’s first day of life until the first farrowing can lead to poor offspring performance and survivability.

摘要

Modern maternal-line genotypes have impressive farrowing performance, increasing litter size by approximately 0.33 pigs per litter per year since 2006 (Tokach et al., 2019). One of the keys to continually improve litter size is genetic improvement through gilt introductions. However, deficient management strategies in gilt development spanning from the gilt’s first day of life until the first farrowing can lead to poor offspring performance and survivability.
