Genetic implications of a bivariate threshold model for litter size components.

Journal of animal science - 1 Nov 1994

Pérez-Enciso M, Foulley J L, Bodin L, Poivey J P

Abstract excerpt

A bivariate threshold model for ovulation rate and embryonic survival was developed and the genetic relationships in the observed scale among ovulation rate, embryonic survival, and litter size were derived. This model was applied to data of nulliparous Lacaune sheep. Heritabilities assumed were .30, .05, and .12 for ovulation rate, embryonic survival, and litter size, respectively. Three values for genetic...
