Effect of Strain and Sex on Carcass Characteristics of Three Commercial Broilers Reared in Deep Litter System in the Derived Savannah Area of Nigeria

The effect of strain and sex on the carcass characteristic of three commercial broiler strains reared in deep litter was investigated. A total of 90 birds from Anak, WadiRoss and Ross strains (30 individual birds per strain and 15 individual per sex) were randomly taken as a representative sample and were slaughtered and carcass dissected manually. The parameters for all breeds and sexes studied included the weights of live body, carcass, shank, breast, drumstick and gizzard. Regarding to all parameters collected, strain and sex were found to be significantly (P<0.05) different for all carcass characteristics. Anak and WadiRoss male strains had significantly (P<0.05) higher values of live body weight, shank, drumstick and gizzard than their female groups. This was in contrary measured in Ross male strain that showed lower values of live body weight, carcass, breast drumstick and gizzard than their female groups. The interaction between strain and sex had no significant effect. Regardless the sex, the high significant measurements of live body weight and breast muscles was recorded for Anak, WadiRoss and Ross strains. Regardless the strain, the males have the highest live body weight for Anak and WadiRoss. The only one high female body weight is recorded for Ross strain compared with their male groups.
