Ovulation rate and twinning rate in cattle: heritabilities and genetic correlation.

Journal of animal science - 1 Aug 1991

Van Vleck L D, Gregory K E, Echternkamp S E

Abstract excerpt

Repeated measures of ovulation rate on puberal heifers should be an effective way to select for increased twinning rate. A reliable estimate of the genetic correlation between ovulation and twinning rates is needed to implement such selection and to predict its efficiency. Restricted maximum likelihood was used to estimate genetic correlations from subsets of data collected from the twinning project at the Roman...
