GROWTH PERFORMANCE OF BROILER CHICKENS FED DIET SUPPLEMENTED WITH BIONIC PREBIOTIC (HILYSES) AND HARDCORE YEAST CELL WALL

Abstract

In a bid to boost productivity, several dietary manipulations have been carried out on poultry, ranging from inclusion of growth promoters, hormones, organic acids, enzymes (Chuka and locally sourced additives Thus, this study was carried out to assess supplementation of regular diet of broiler chickens with bionic prebiotic (Hilyses) and hardcore Yeast Cell Wall (Immuno Wall). 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 consisting of 30 chicks and replicated three times. The initial live weight of the broiler chicks at day old was recorded. The birds were weekly weighed to determine the live weight and weight gain. The quantity of feed offered to the birds daily and the left over the next morning were measured to ascertain feed intake. Mortality was noted. Over the 56-day experimental period, the results demonstrated notable improvements in various performance traits attributable to the inclusion of prebiotic and yeast supplements, except for the initial weight, which exhibited not statistically significant (P>0.05) difference among the treatment groups. Significant (p<0.05) differences were observed in the final weight, with birds fed diet 4 displaying the highest final weight, reaching 2680.85g. In contrast, the final weights of birds fed diet 3 and 2 were 2525.55g and 2450.10g, respectively, while those on diet 1 had the lower final weight of 2407.65g. It is worth noting that as the inclusion levels of prebiotic and yeast increased across the dietary treatments, a significant (p<0.05) enhancement in final weight was consistently observed. The findings of this study unequivocally demonstrate the favourable growth performance of the treatment diets across all
parameters examined. Specifically, it is evident that T4, with a 0.75% inclusion of prebiotics and yeast cells, yielded the highest final bod weight than both the other trial diets and the control diet. These findings highlight the potential for enhanced broiler chicken performance and overall health when incorporating these dietary additives.
