In a 12 week experiment the effect of graded levels of soaked sesame seed meal
(SSM) as a source of methionine on the performance of laying hens was investigated.
In a completely randomized design, 200 black Australorp pullets aged 20 weeks
were allotted to 5 isonitrogenous diets with 4 replicates of 10 birds per diet.
Sesame seed meal (SSM) replaced soyabean meal (SBM) weight for weight at 0.00,
12.50, 37.50 and 50.00% in diet 1 (control), 2, 3, 4 and 5 respectively. The control
diet contained synthetic methionine which was removed with the introduction of
SSM in the other diets. The results showed a significant (P< 0.05) reduction in
the hen-day egg production above 25.00% and egg weight above 12.50% levels of
replacement. Shell quality was not affected by dietary treatment. Feed cost (N/egg)
was significantly (P < 0.05) reduced on the 12.50% replacement compared to the
37.50%. There was no treatment effect (P> 0.05) on the while blood cell count,
but packed cell volume was significantly (P< 0.05) lowered on the 50.00% and
haemoglobin concentration, serum protein, albumin and globulin above 12.50% levels
of replacement. These results suggest that replacing SBM with SSM at 12.50% in
the diet of laying hens will meet their methionine requirement without adverse
effects on performance and health status.
