Influence of Biozyme Supplementation on Broiler Chickens Fed Diet Containing Rice Bran

The study was conducted at Kazaure in the semi-arid zone of northern Nigeria between latitude 120 41’ 28.7’’- 130 00’N and longitude 070 50’E- 080 25’ 21.1’’E with temperature ranges from 15.850C - 390C for a period of Eight weeks, to determine the intake and carcass quality of broiler chickens fed diet containing rice bran with biozyme supplementation. Ninety-six (96) day- old broiler chickens were used for the study. The birds were randomly grouped in to four treatments, and replicated three each, with eight birds per replication. Four experimental diets each for starter and finisher were formulated such that, diet 1 (control) contained rice bran with 0% enzyme (biozyme) and diets 2, 3 and 4 contained rice bran with varying proportions of biozyme at 7%, 14% and 21% respectively. The four treatments were allocated to those four experimental diets accordingly, and laid on a Completely Randomized Design (CRD). Initial body weight, daily feed intake, weekly weight gain, final weight and carcass weight of randomly selected birds were recorded. The result obtained for daily feed intake indicated no significant difference (p>0.05) observed among the treatments. The findings for the growth performance revealed a significant difference (p
