Abstract
Data from 802 lambs representing 58 sire groups were analyzed to determine relationships between live and carcass traits. Genetic correlations indicated some antagonism between fleece growth and body growth (weaning weight and A.D.G. on test) for lambs fed to a relatively constant weight.Negative genetic correlations were also found between fleece weights or staple length and traits related to carcass meatiness (longissimus area and retail cut weight). Genetic correlations between amount of fat and amount of lean were negative. No serious antagonism was apparent between growth rate and carcass desirability. Consequences of negative relationships between important traits were discussed. Copyright © 1971. American Society of Animal Science . Copyright 1971 by American Society of Animal Science.
