Effect of multienzymes + probiotic supplementation in fermented shea butter cake based diets on the carcass traits and the biochemistry of broiler chickens

Abstract. This study aimed to evaluate the effect of multienzyme+probiotic (MEP) supplementation on carcass characteristics and serum biochemistry of broiler chickens fed fermented shea butter cake meal (FSBCM) based diets. A total of two hundred and sixty (260), 28-day-old broiler chicks were distributed into four treatments, with five replicates of 13 birds each using a completely randomized design and reared on deep litter system from 28 to 56 days of age. The four treatments were: positive control – T1 (corn-soybean based diet); negative control – T2 (20% FSBCM replacement for corn in T1); diet 3 – T3 (T2 diet + 0.05% MEP) and diet 4 – T4 (T2 diet + 0.10% MEP). On day 56, two birds per each pen were selected for carcass and organ evaluation and other two birds per replicate were selected for serum biochemical analysis. The results indicated that addition of MEP to FSBCM diet caused a significant (p<0.05) increase in live weight, dressing percentage and breast meat yield than FSBCM diet without MEP and did not differ from the T1 diet. The abdominal fat in birds fed MEP treated diets were significantly (p<0.05) lower than those groups fed PC and FSBCM diets. Serum glucose was similar (p>0.05) between birds fed PC and MEP treated diets but significantly (p<0.05) higher than those on FSBCM diet, whereas serum cholesterol, alanine aminotransferase and aspartate aminotransferase concentrations reduced significantly (p<0.05) in groups fed MEP supplemented FSBCM diets. All other parameters were not significantly (p>0.05) affected by the MEP supplementation. Therefore, MEP supplementation in FSBCM based diet improved live weights and carcass attributes without any detrimental effect on blood composition of the broiler chickens.
