ABSTRACT:

This work was undertaken to evaluate the effect of varying protein concentrations on the performance and carcass yield of broiler chickens. One hundred and twenty day old Hubbard Golden Comet broiler chicks were used in this feeding trial. They were randomly distributed into 3 dietary groups of 40 birds each. Three isocaloric (12.13MJME/kg) diets varying in protein concentrations (18, 21 and 24%) were fed to the groups of 40 birds in diets 1, 2, and 3 respectively. The experiment lasted 8 weeks. The result showed that birds fed 18 and 21% protein diets had significantly (P < 0.05) lower body weights compared with birds fed 24% protein. The percent carcass yield was also significantly (P<0.05) influenced by the treatment di,?ts. Birds fed 18%CP gave the least {2. 77%) abdominal fat; followed by birds fed 24% and 21% respec:tively. Birds fed 18%CP gave the highest gross margin (N) and carcass quality while 24% dietary protein with 12.13MJ/kg metabolizable enerov enhanced growth rate and carcass yield.
