EFFECTS OF LYSINE SUPPLEMENTATION ON PERFORMANCE CHARACTERISTICS AND MINERAL RETENTION OF BROILER CHICKENS FED RAW BENNE SEED BASED DIETS
Abstract: The objective of the
study was to determine the effects of raw benne seed (RBS, Sesamum indicum) with
or without lysine supplementation on the performance characteristics and
mineral retention of broiler chickens. The feeding trial lasted for 56 days.
One hundred and forty unsexed day old
broiler chicks (Marshall strain) were used for the study. RBS was
incorporated into the diets at 15% and 30% levels and supplemented with 0%, 0.25% and 0.5% of lysine, respectively.
Average weekly feed intake in birds fed
the control diet and 15% RBS based diet supplemented with 0.25 % and 0.5%
lysine were not significantly different, but significantly (P<0.05) higher
than those fed other diets. Feed conversion efficiency and protein efficiency
ratio were significantly (P<0.05) reduced in birds fed 30% RBS with or
without lysine supplementation. At 0.25% and 0.5% lysine supplementation,
significant (P<0.05) increases were obtained in the retention of nitrogen,
calcium, phosphorus and iron in birds fed 15% RBS based diets, but markedly
reduced in those fed 30% RBS based diets.
The reductions in the performance characteristics of the birds fed 30% RBS
diets with or without lysine can be attributed to interactions in the toxic
effects of the higher intakes anti-nutritional factors like tannin, oxalate and
phytate. In conclusion, the response indices were better enhanced
when 15% RBS supplemented with 0.5% lysine was fed to the birds.
