Carcass responsesQuadratic effects of dietary CP as CP×ME interactions were found on carcass yieldof birds reared in hot climate. Improvement in breast weight was noted on low ME dietswith moderate dietary CP (Table 3). A linear effect of dietary CP was noted on breastyield.It was observed that dietary ME levels had a significant effect on the abdominal fatpad. A high correlation coefficient (P<0.002) of 0.67 was observed between dietary MEand abdominal fat pad. No effect of dietary CP was observed on abdominal fat pad. Theresults indicated that abdominal fat did not significantly increase with decreased in dietaryCP level if low protein diets were supplemented with essential amino acids. No significant308 Q.U. Zaman et al. / Animal Feed Science and Technology 146 (2008) 302–312differences were noted for heart, liver and gizzard weights of broiler birds fed differentexperimental diets except for increased liver weight with increasing dietary ME. Resultsindicated that ME had no effect on carcass, breast, heart and gizzard weights of the birds.
