Some studies on breeding market pigs by crossing Duroc with Beltsville No. 1 for meat-type hogs.

Abstract

Much discussion in Kansas has concerned the desirability of crossbreeding inbred breeds (so-called hybrids) with other breeds for meat-type hogs. Consequently, a Beltsville No.1 (Poland x Landrace origin) was secured and matings planned with a Duroc. The test was to study vigor and size of the litter produced and ultimate performance in the feedlot of the litter compared with performance of purebred Duroc pigs raised under comparable conditions. In the winter of 1953-54, six purebred Duroc sows were mated to a Duroc boar, and six Duroc sows were mated to a Beltsville No.1 boar.
