Response Of Finisher Broilers To Antibiotic and Enzyme-supplemented Diets

A 28 – day feeding trial was conducted to evaluate the response of finisher broilers to antibiotic (neocloxin) and enzyme (Roxazyme G) supplemented diets. Three experimental diets were formulated such that diet 1 had neither enzyme nor antibiotic supplementation. Diets 2 and 3 contained antibiotic and enzyme supplementation at 200mg/kg respectively. 72 5-week-old Anak broilers were randomly assigned to the three treatment diets in a Completely Randomized Design and each treatment was replicated thrice. Feed and water were provided ad libitum. Measurement recorded included feed intake, body weight gain and feed conversion ratio. Result showed significant variations (P 0.05) difference between the feed intake of birds on T1 and T2 diets. Results of the trial suggest that neocloxin and Roxazyme G enzyme could be incorporated in broiler finisher diet as growth enhancers since they positively affected the performance of the birds. Key words: Finisher broilers, antibiotic, enzyme, performance, growth enhancers. Journal of Agriculture, Forestry and the Social Sciences Vol.2(2) 2004: 35-4
