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.

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.
