Chicks, Cassava peel meal, Enzyme supplement, Haematological profile, Roxazyme® G2G.

A feeding trial was carried out to investigate the response of broiler chicks to cassava peel meal supplemented with Roxazyme® G2G. Cassava peel meal based diet containing 0, 20 and 40% at the expense of maize was divided into 3 equal portions; each portion had 0, 100 and 200 mg/kg Roxazyme® G2G supplementation to make a total of nine diets. A total of 450 day old broiler chicks with weight range between 396 and 401 g were randomly distributed to the diets in a 3 × 3 factorial arrangement at 50 chicks per treatment; replicated five times of ten birds per replicate. The results obtained shows significant decrease (p<0.05) in final live weight (FLW), (554.65 g versus 510.11 and 521.00 g), average weight gain (AWG) (24.02 g/b/d versus 21.90 and 22.08 g/b/d) and average feed intake (44.23 g/b/d versus 42.02 and 42.83 g/b/d) of broiler chicks at 0% vs 20 and 40% cassava peel meal, respectively. While the feed conversion ratio (FCR) was not significant (p>0.05). Enzyme supplementation improved performance of broiler chicks by 2.39 and 5.87% in the FLW, 3.88 and 7.63% in average daily weight gain (ADWG), 6.03 and 7.54% in FCR over birds fed non-enzyme supplemented diets. Haematological and serum indices of the birds were similar, irrespective of enzyme supplementation. From the findings of this study, an optimum supplementation of Roxazyme® G2G at 100 mg/kg of either 20 or 40% cassava peel meal substitution in broiler chick diet is recommended.
