Enzymes Effects On Carcass- Attributes, Organ- Characteristics, Meat- Qualities And Sensory -Evaluation In Broiler (Gallus Domesticus Brizzen ) Fed Gliricidia Sepium (Jacq) Leaf Meal

Abstract

An eight weeks feeding trial was conducted to evaluate the Carcass and Organoleptic properties of broiler birds fed Gliricidia leaf meal with enzymes supplementation. Gliricidia sepium (jacq) is a multipurpose browse tree. Four broiler diets were formulated to contain 0% GLM without enzyme, 5% GLM without enzyme, 5% GLM with enzyme (Roxazyme G2^®), 5% GLM with enzyme (Maxigrain^®). Ninety six day old chicks Rock cornish strain were distributed into four treatments of three replicates each using complete randomized design (CRD). Data was collected on Organoleptic, Sensory evaluation, and Carcass attributes. There was significant differences (p>0.05) in Sensory evaluation among the control diet (0.0% GLM without enzyme) and treatment 4 (5% GLM with enzyme (Maxigrain^®) which was observed to be better than the control diet (0% GLM without enzyme). Organoleptic characteristics of birds on 5% GLM with enzyme (Maxigrain^® ) diet did not significantly differ (p>0.05) from birds on 0% GLM without enzyme supplementation. There were significant differences (p>0.05) in the Carcass attributes and Organ characteristics of the experimental birds. This result suggests that 5% of GLM with enzyme (Maxigrain^®) can be fed to broilers and doesn’t have any residual or adverse effect on raw, eating and cooking quality of meat and hence is safe for usage.
