Egg- qualities ,Organs- weight and Carcass-attributes of laying hens (Gallus domesticus brizzen ) fed Gliricidia sepium leaf meal levels supplemented with Maxigrain

摘要

Sixty(60) laying hens (Rhode Island Red strains) products were investigated after being fed Gliricidia leaf meal (GLM) supplemented with Maxigrain? enzyme The birds were randomly allotted to five dietary treatments of 12 birds per treatment; each treatment was replicated into 4 groups with 3 birds per replicate. Five experimental diets were formulated; the test ingredient being Gliricidia sepium. Three of the diets were formulated with enzyme supplementation i.e. diets, C, D, E while diet A(control) was without enzyme supplementation and B( control with enzyme). Gliricidia sepium leaf meal was included at 5%, 7.5% and 10% replacement of dietary soyabean meal in diets C, D and E respectively. The feeding trial lasted for twelve weeks after which egg qualities, organ indices and carcass variables were monitored. data collected were analysed using One-way ANOVA, Of the egg qualities,apart from henday production, haugh unit, albumin weight and index all other qualities were highest in 5%GLM,Also the best organ traits indices ,dressed weight was highest in 5%GLM .Concerning carcass characteristics 5%GLM recorded the highest (P<0.05) in all other characters except breast, shank, and neck weights 5%GLM supplemented with Maxigrain? will serve as a potential abundant non-conventional source of ingredients and also as a source poultry products with high human preference and maximum satisfaction.
