In this study, response to selection for 3-week oxigen consumption and correlated responses for 3- and 8- week body weight were evaluated. In addition, the magnitude of genetic parameters were estimated for these traits. The data utilized were from a two-way selection experiment conducted at the University of Kentucky. Selection for high and low 3-week ixygen consumption was the only criterion of selection. The data were analyzed separately for each sex, since sex was in some cases confunded with hatches. The realized response to selection per generation for 3-week oxigen consumption ranged from 0.082 ml/100 grams/min to 0.351 ml/100 grams/min. Selection for low oxygen consumption actually resulted in a slight increase in oxygen consumption. The realized correlated response to selection per generation for 3-week body weight ranged from -3.095 grams to -5.769 grams, while the correlated response for 8-week body weight ranged from -8.282 grams to -25.827 grams. The realized heritability for 3-week oxygen consumption ranged from -0.094 to 0.157. The population parameter heritability estimates for 3-week oxygen consumption, 3-week body weight, and 8-week body weight, respectively, ranged from 0.024 to 0.191, from 0.236 to 0.524, and from 0.221 to 0.580. The realized genetic correlations between 3-week oxygen consumption and 3- and 8-week body weight ranged from -0.739 to 0.062. The population parameter genetic correlation estimates between 3-week oxygen consumption and 3- and 8-week body weight ranged from -0.153 to -0.069, while the correlations between 3- and 8-week body weight ranged from 0.660 to 0.711.
