This study investigated the effect of animal and plant lipids in the diets of broiler finisher birds with respect to their growth performance and abdominal fat deposition. A total of 360 birds of mixed sexes were completely randomised into three dietary treatments A, B and C with 0, 4% animal lipid and 4% plant lipid as replacements for maize respectively. Each treatment was replicated thrice with each replicate having 40 birds. Result showed significant improvement (P < 0.05) in feed intake of birds on lard, followed by palm oil and then the control in that order. Final live weight and weight gain were significantly (P < 0.05) better for birds on lard followed by palm oil, likewise feed conversion ratio was significantly (P < 0.05) better in both lard and palm oil diets than the control diet. The protein efficiency ratio followed a similar trend like the feed convention ratio with better (P < 0.05) protein utilisation witnessed by birds on palm oil and lard diets. The cost/kg feed intake did not show any significant differences likewise the cost/kg weight gain. Among the nutrient retention parameters, only ash and ether extract showed significant (P < 0.05) differences, with birds on the control diet having significantly (P < 0.05) higher ash content than both lard and palm oil diets. Ether extract was better retained by birds on lard, followed by palm oil. The liver and heart of birds on lard and palm oil were heavier than that of the control. Birds on diet containing lard had the highest (P < 0.05) abdominal fat followed by birds on palm oil diet. It was concluded that 4% animal fat (lard) (replacing maize) as an energy source enhances growth performance than palm oil in broiler finisher diets but with attendant abdominal fat deposition.
