  • Abstract:

The current cassava initiative by Nigerian government has led to the generation of huge cassava tuber wastes (CTWs). These wastes, which contribute to environmental pollution, can however be harnessed as very cheap alternatives to the expensive conventional animal feedstock, especially when they are subjected to microbial fermentation. This experiment was therefore conducted to investigate the effects of using two microbial fermented cassava tuber wastes (MFCTWs) feedstock on carcass and organ morphometry of broiler birds. Seven experimental diets designated as Diet 1 (0% MFCTWs), Diet 2 (20% MFCP), Diet 3 (40% MFCP), Diet 4 (60% MFCP), Diet 5 (20% MFCSR), Diet 6 (40% MFCSR) and Diet 7 (60% MFCSR) were fed to the birds. The carcass and organ parameters were taken at the end of eight weeks of experiment. The results showed that carcass and organ morphometry differed significantly among the treatment diets. Carcass morphometry revealed that the breast, drumstick and thigh were not significantly affected when the two CTWs were used up to 40% level for MFCP and 20% for MFCSR respectively. The small intestine of birds fed CTWs were longer than those fed the control diet while the large intestinal length showed a progressive decrease with increasing dietary levels of CTWs. It was concluded that these CTWs may be included up to 40% level without adversely affecting choice portions of the carcass. Their utilization could however result in an increase the length of the small intestine and the relative weight of the kidneys, proventriculus and pancreas.
