Performance and carcass characteristics of finisher broilers fed 75% fermented urea plus (+) methionine treated sorghum beer residue (RSBR) diets supplemented with and without enzymes (Nutriad® (N), Zymos-N® (Z) and Fullzyme® (F)) were investigated. Three hundred (300) 4-weeks-old broilers were randomly assign to five (5) dietary treatments with three (3) replicates (15 pens), each consisting of twenty (20) birds in a completely randomised design. The dietary treatments were formulated to be iso-nitrogenous and iso-caloric such that diets 1 (control), 2, 3, 4, and 5 contained 0% RSBR, 75% RSBR, 75% RSBR + N, 75% RSBR +Z and 75% RSBR +F respectively. The research lasted for 28 days. Daily feed intake and weight gain of birds on diets +N and +Z were similar but significantly higher (P<0.05) than those on control, 2 and 5 (+F) diets. Feed to gain ratio was least with birds on +N diet and highest with birds on diet without enzyme. No mortality was observed with birds on +N and +Z diets. The least feed cost per kg gain was shown by birds on +N diet compared to those fed other diets. The dressing and thigh weight percentages were significantly higher for birds’ fed +N diet compared to those on control and other diets. The breast percentage for birds on +N and +F were similar but significantly higher compared to those of birds on other diets. The heart and gizzard percentage for birds on un-supplemented diet (75% RSBR) were significantly higher (P<.0.05) compared to that for birds on other diets.
It could be concluded in this study that Nutriad®, Zymos-N® and Fullzyme enzymes supplementation improves the performance of birds on 75% fermented urea plus methionine sorghum beer residue level of inclusion in broiler diets. Moreover, the economic cost of raising broilers on diets with +N, +Z and +F supplementation was lower. The present findings suggest that diets contained fermented urea plus methionine treated sorghum beer residue up to 75% and supplemented with either +N, +Z and +F multi-enzymes can be used as an alternative source of protein for broiler finisher diets and can replace GNC up to 75% without adverse effects on the growth performance and carcass characteristics.
