Increased litter size in Rambouillet sheep: I. Estimation of genetic parameters.

Journal of animal science - 1 Nov 1992

Waldron D F, Thomas D L

Abstract excerpt

The variance and covariance components needed to estimate heritabilities of and genetic correlations among litter size, ovulation rate, scrotal circumference, and BW in a flock of Rambouillet sheep were estimated using REML via an expectation-maximization type algorithm. The heritability estimates from univariate analyses were .14, .21, .25, .36, and .15 for litter size, ovulation rate, scrotal circumference,...
