CARCASS CHARACTERISTICS AND LIPID PROFILE OF BROILER CHICKENS FED THREE SEED CAKE-BASED DIETS WITH AND WITHOUT MULTIENZYMES SUPPLEMENTATION

Abstract

The study was conducted to evaluate the impact of feeding three seed cake-based diets partly substituting soya bean cake with and without multienzymes supplementation, on carcass characteristics and lipid profile of broiler chickens. In feeding trial one and two, 352 and 330 Cobb 500 day old broiler chicks were allocated to four and five dietary treatments respectively. In trial one; the diets contained Groundnut cake (GNC), Roselle seed cake (RSC) and Baobab seed cake (BSC); while in trial two, it contained BSC and RSC with and without multienzymes, all in a completely randomized design, at 20% inclusion level for 49 days each while diet with maize-soya bean cake based diet served as control. Four and five nitrogenous diets with 23 and 20% crude protein were formulated for starter and finisher phases respectively. From the results, Breast weight was higher (P˂0.05) for birds fed SBC (29%) and RSC (30%) without multienzymes, birds fed RSC had least (P˂0.05) cholesterol (79.60 mmol/L) and low density lipoprotein levels (13.30 mmol/L). Carcass characteristics of some cut parts (breast and back), organs (liver, heart, gizzard and lungs), abdominal fat were significant (P<0.05) with multienzymes addition while lipid profile of the birds were not significantly (P>0.05) affected with multienzymes supplementation.
