Abstract
ABSTRACT Proximate and Amino acid analyses of beniseed and Moringa leaves were carried out. This was followed by two feeding trials conducted to evaluate Beniseed (Sesamum indicum) and Drumstick tree (Moringa oleifera) leaf meals as potential feed ingredients and as sources of methionine in Broiler diets. Experiment one was carried out to compare the growth performances of 40 broiler chicks with 20 chicks each on raw or cooked Moringa leaf meals. There were two replicates of 10 birds each for the raw and for the cooked Moringa leaf meals to determine if raw Moringa leaf meal can be safely fed in broiler diets. In experiment two, 252 broiler birds were used for the starter and finisher phases of the experiment on seven dietary treatments comprising of control, three of beniseed diets and three of Moringa leaf meal diets in a completely randomized design. The control diet contained neither the beniseed nor the Moringa leaf meal. The three beniseed diets contained (a) 6% beniseed plus 0.25% methionine or (b) 6% beniseed plus 0.125% methionine or (c) 6% beniseed without methionine supplementation. The three Moringa diets also contained (a) 6% Moringa leaf meal plus 0.25% methionine or (b) 6% Moringa leaf meal plus 0.125% methionine or (c) 6% Moringa leaf meal without methionine supplementation. The results for the proximate analyses showed that beniseed had a crude protein content of 23.13%, raw Moringa leaf had 25.25% crude protein, while cooked Moringa leaf had a crude protein of 22.44%. The amino acid composition showed that beniseed had 0.87% methionine and 0.99% cystine. vi ii Moringa leaf on the other hand had 0.26% methionine and 0.17% cystine. The results for experiment 1 showed that there were no significant differences (P>0.05) in terms of final weights (749.85g/bird and 754.27g/bird) and average daily gains (25.31g/bird and 25.47g/bird) between broiler chicks on the raw Moringa leaf meal and those on cooked Moringa leaf meal respectively. Broiler chicks on cooked Moringa leaf meal gave significantly (P<0.05) higher cost of feed per kg gain than those on raw Moringa leaf meal. The results for experiment 2 for both the starter and finisher phases showed that broilers fed Moringa leaf meal at 6% dietary level gave better results in terms of final weight and average daily gains than broilers fed the control or the beniseed diets. Birds on 6% Moringa leaf meal diet without supplemental methionine performed equally well as birds on the control diet (P>0.05) and significantly better than birds on the beniseed diets without supplemental methionine (P<0.05). Carcass characteristics of the broilers at nine weeks of age, showed no significant differences (P>0.05) among dietary treatments in terms of the choice parts of the carcass (breast, thighs and drumsticks). Raw Moringa leaf meal could be used at 6% dietary level in broiler finisher diets without any adverse effect on growth performance. It was also observed that the use of Moringa leaf meal can partially or wholly replace the required level of supplemental methioninix. Title page - - - - - - - - - i Declaration - - - - - - - - - ii
