Reproductive traits of sows in two-way crossing

Abstract

The article presents the results of research into reproductive traits of sows in pure breeding and crossbreeding. It shows the advantage of the ♀LW × ♂L variant of crossing in most of the traits. The sows manifested high indices of reproductive traits. An increase in litter size led to a higher litter weight on the 21st day of the suckling period, the correlation being between r = 0.65 in LW sows and r=0.81 in sows of the ♀P × ♂D group.
