Reviewing the potentials of some unorthodox energy feedstuffs: A panacea to sustainable animal agriculture in Nigeria

Abstract

Utilization of some lesser known energy feed ingredients in animal agriculture was appraised.
Fermented cassava meal and maize offal appeared to be most promising alternative replacement for
maize in diets for broilers and laying hens with 100 % dietary inclusion (p>0.05). Palm oil sludge, guinea
corn and spent grain have also been reported to replace maize up to 50% dietary level in fish and poultry
diets without compromising performance; however, it was revealed that raw cocoyam and sweet potato
cannot be tolerated beyond 30% dietary inclusion in fish and poultry diets (p<0.05) without adverse effect
on production. Nevertheless , all the unorthodox feed resources were found to be economically viable
alternatives to maize in practical diets for fish and livestock production towards the realization of cheap
and sustainable animal protein intake for Nigerians.
