Abstract

This study estimated the magnitude of sexual dimorphism, i.e. sex specific heritabilities and correlations between ewes and rams for weaning, post weaning, yearling and hogget weights in 3 sheep breeds (Coopworth, Poll Dorset and White Suffolk). Rams were heavier than ewes at all ages, but higher heritability estimates were observed for ewes, although few of these differences were significant. Genetic correlations between ewes and rams varied from 0.97 to 0.59 and decreased with increasing age at measurement.
