Abstract EN

The present research aims to investigate the effect of soybean meal (SBM) replacements by 0, 25, 50 and 75% of local sesame meal (LSM) in the diet on the production performance, blood serum constituents, carcass traits and economic efficiency of broiler chickens.

A total of 240 broiler chickens (Ross 308) were involved in this study.

After two weeks of adaptation period, the 15 day-old birds were distributed randomly into the four groups of treatment with 3 replicates (20 birds each) based on completely randomized design (CRD).

The average of body weight, daily weight gain, feed conversion ratio, specific growth rate, feed consumption, feed conversion efficiency, dressing percentage and economic evaluation were measured continuously.

The present study results revealed no significant differences in the average of body weight and daily weight gain, feed conversion ratio, specific growth rate, feed intake, feed conversion efficiency, body weight, carcass weight and economic efficiency at 25% of LSM during 15, 22, 28, 36, 43 and 45 days of age compared to the control treatment.

The SBM replacement with 50 and 75% of LSM resulted in significant decrease of the previous parameters.

Despite that the dressing percentage was significantly reduced by increasing the replacement percentage of LSM was observed.

However, the blood serum total protein was significantly decreased (P<0.05) and the blood serum glucose was significantly increased (P<0.05) by increasing the percentage of replacement with LSM compared to the control treatment.

The present study findings indicated that replacing the SBM by 25% of sesame meal did not result with any adverse effect on the performance of broiler chickens.
