CARCASS CHARACTERISTICS AND ORGAN WEIGHT OF BROILER CHICKENS FED DIET SUPPLEMENTED WITH BIONIC PREBIOTIC (HILYSES) AND HARDCORE YEAST CELL WALL

Résumé

The discovery that the use of antibiotic in food animals is fueling the increasing problem of transmitting resistance bacteria from food animals to man has led to the search for an alternative to the use of antibiotics. To this end, the supplementation of broiler chickens' straight diet with Bionic Prebiotic (Hilyses) and Hardcore Yeast Cell Wall (Immuno Wall) on carcass characteristics and organ weight was investigated. The experiment utilized a Completely Randomized Design (CRD) with 120 unsexed day-old chicks randomly allocated into four treatment groups (T1, T2, T3, and T4), each
consisted of 30 chicks and replicated three times. Carcass and organ weight was measured and determined at the 8th week. The carcass results obtained indicate significant (p < 0.05) differences among the treatment groups for live weight, dressed weight, dressing percentage, thigh, and back cuts. In particular, the live weight of birds that were fed diet 4 (2680.85g) was found to be significantly (p < 0.05) higher compared to birds fed diet 3 (2525.55g). On the other hand, birds fed diet 1 (2407.65g) and diet 2 (2450.10g) exhibited the lower live weight values. It is noteworthy that the live weight increased significantly across the dietary treatments as the levels of prebiotic and yeast inclusion in the diets increased. In the context of the poultry industry, a paramount objective is to maximize yield percentage, obtain saleable products, and subsequently enhance the edible portions of the birds. Typically, the incorporation of feed additives has the potential to augment metabolic rates, leading to favourable changes in the size of several internal organs, as evidenced in this study. These findings highlight the potential for enhanced broiler chicken performance and overall health when
incorporating these dietary additives.
