Evaluation of microdesmis puberula leaf meal as feed ingredient in broiler starter diets

Abstract

A 21-day feeding trial was conducted to evaluate the leaf meal of Microdesmis puberula as feed ingredient in broiler starter diets. Microdesmis puberula is a preferred tropical browse plant. The leaves were harvested, chopped to facilitate drying, spread evenly in a room for four days until the material becomes crispy while still retaining it's greenish colouration. The material was milled using a hammer mill to produce the leaf meal. Microdesmis puberula leaf meal contain 17.32% crude protein, 6.52% ether extract, 12.25% total ash, 24.84% crude fibre, 24.06% NFE and an appreciable percent of minerals. Three broiler starter diets were formulated to contain the meal at dietary levels of 0%, 5% and 10% One hundred and eighty (180), 14 -day old hubbard broiler chicks were divided into three groups of sixty birds each and randomly assigned to the three treatment diets in a completely randomized design (CRD). Data were collected on feed intake, body weights and feed conversion ratio. There were significant (P<0.05) differences in feed intake, body weight gain and feed conversion ratio among the group on the control (0%) diet and the groups on diets containing 5% and 10% inclusion levels of the leaf meal. The group on the control (0%) diet performed significantly (P<0.05) better than the groups on the leaf meal diets. The results of this study suggest that dietary inclusion of Microdesmis puberula leaf meal at 5% and 10% levels significantly (P<0.05) depressed performance of broiler chicks,
