Estimation of direct and maternal genetic variance for litter size in Canadian Yorkshire and Landrace swine using an animal model.

Journal of animal science - 1 Jul 1990

Southwood O I, Kennedy B W

Abstract excerpt

Estimates of additive direct heritability (h2a) for traits such as litter size may be biased by maternal effects. The size of these effects was estimated using a derivative-free restricted maximum likelihood procedure under an animal model. First-parity records from Yorkshire (Y) and Landrace (L)...
