Comparative study of the effect of dietary energy on female carcass quality and chemical composition of two broiler strain crosses

Abstract EN

This study was conducted at the Poultry Farm of the Animal Resources Department during the first three months of 1999, College of Agriculture and Forestry - University of Mosul, to investigate the effect of using different dietary levels of metabolizable energy on the carcass quality and chemical composition of two female broiler strains reared under conventional environmental conditions in Iraq .

One - day old White Ross and Iraqi Fawbro broiler chicks were reared on a deep litter at the rate of 180 birds per strain .

The birds from each strain were randomly distributed to three dietary treatments with different metabolizable energy levels (2812,2709,2896) and (2839,2744,2918) for Tl, T2, and T3 during both starting and growing periods, respectively.Eacb treatment contained three replicates with 20 birds per replicate.
