Abstract

Two experiments were conducted to investigate the effects of fermented sesame meal (FSM) replacement by soybean meal (SBM) in broilers. In the first experiment, a completely randomised design with 3 × 4 factorial arrangement was used for microorganism comparison [Lactobacillus acidophilus (LA), Saccharomyces cerevisiae (SC) and LA + SC] and fermentation time courses (0, 2, 7, and 12 days). In the second experiment, a total of 420-day-old boilers (Ross 308®) were randomly allocated to seven treatments and five replicates. The experimental treatments include basal diet based on soybean meal (SBM), SBM substituted with 15 and 25% raw sesame meal (RSM) with and without phytase (PHX); RSM15, RSM25, RSM15 + PHX, and RSM25 + PHX, and SBM substituted with 15 and 25% FSM; FSM15 and FSM25. Results showed that, in the fermentation process, the main effects of microorganism and days of fermentation significantly affected the pH and crude protein (p < .05). Also, the main effect of day of fermentation was found significant for phytic acid, oxalate and crude fibre (p < .05). The crude protein was increased when a mixture of LA and SC was used (p < .05). Broilers fed RSM25 had the lowest and the highest BWG and FCR, respectively, than those fed other diets on day 42 (p < .05). Compared to all diets except for RSM15, RSM25 a reduction was recorded for phosphorus digestibility (p < .05). In conclusion, fermentation process improved the nutrient value of the RSM and subsequently performance of the broilers and could be used as a protein source in broiler diets.

    Highlights

  • Fermentation process leads to significant decrease in phytic acid content of sesame meal.

  • Raw sesame meal had adverse effects on the performance of broilers.

  • Fermented sesame meal may improve the broilers performance similar to soybean meal.
