Abstract

A study was carried out to determine the effects of dietary levels of enzyme supplemented yam peel meal (YPM) on performance and carcass characteristics of weaner rabbits. Five diets were formulated using YPM to replace maize at 0%, 25%, 50%, 75% and 100% representing diets 1, 2, 3, 4 and 5 respectively. All the diets were supplemented with Mixagrain® enzyme at 200g except the control diet 1 (0%). Thirty weaner rabbits consisting of mixed breeds and sexes were randomly allotted to the five dietary treatments with six rabbits per treatment and replicated 3 times with 2 rabbits per replicate in a completely randomized design. On the 56th day of the experiment, 3 rabbits from each treatment were randomly selected for carcass and internal organs evaluation. Result of performance shows no significant differences (P>0.05) across the treatments for all the parameters measured for growth performance. Feed cost/kg (₦ /gain) reduces from ₦225.68 in diet 1 – ₦189.15 in diet 5 (100%) while cost savings increased from ₦ 0.9 in diet 1 - ₦28.33 in diet 5 (100%). Result of carcass and internal organs characteristics did not show any significant differences (P>0.05) except for small and large intestine length in diets 4 (75%) and diet 5 (100%). Based on this result therefore, enzyme supplemented YPM can be used to replace maize completely.Keywords: Enzymes, yam peel meal, performance, carcass, weaner rabbits

Highlights

In developing countries including Nigeria, the inadequacy of animal protein intake is well spread and this has greatly affected the living standard of the people
The result of the analysis showed that yam peel meal (YPM) contained 92.86% DM, 10.695 CP, 2.85% ether extract (EE), 8.5% crude fiber (CF), 4.61% Ash and 73.35% nitrogen free extract (NFE)
The crude fiber (CF) which is the amount of indigestible carbohydrates present in the feed sample was lower than the values of 9.47 reported by Aduku (1990) but higher than 7.20% reported by Akinmutimi and Anakebe, (2008), 7.78% (Uchewa et al, 2014). and 6.30% (Ekpo et al, 2015)

Summary

Introduction

In developing countries including Nigeria, the inadequacy of animal protein intake is well spread and this has greatly affected the living standard of the people. The study was carried out to evaluate the effect of Maxigrain® enzyme supplementation on performance and carcass characteristics of weaner rabbits.
