Genotype by mating type interaction for litter size in Landrace and Large White sows
2005
Lewis, T.W. | Wiseman, J. | Woolliams, J.A.
Data obtained from a detailed base from a commercial breeding company of Landrace and Large White purebred nucleus sows were used to estimate genetic parameters of piglet number born alive (NBA) following artificial insemination and natural service. Heritabilities were small but significantly different from zero, and similar to literature estimates. The genetic correlation (r(G)) of NBA after AI or natural service using pooled data was 0.71 and was significantly different from one (P<0.01) but not significantly different between breeds (P>0.1). It is concluded that mating type may result in a re-ranking of sow genetic merit for NBA.
