The effect of different levels of sesame meal by soybean meal with and without phytase enzyme on performance and characteristics of carcass and tibia in Japanese quail

This experiment was conducted to investigate the effects of different levels of sesame meal supplemented with phytase enzyme on performance and characteristics of carcass and tibia in Japanese quail, in a completely randomized design with 2 × 3 factorial arrangement containing, two levels of phytase enzymes (zero and 0.1 g/Kg in diet) and three levels of sesame meal (zero, 25 and 50%) was employed. Three hundred sixty Japanese quail were allocated to 6 experimental treatments with 4 replicates of 15 quail each. The results showed different levels sesame meal, phytase enzyme and their interaction had no significant effect on weight gain, feed intake and feed conversion ratio. Percentage of liver were higher in treatment with 25% sesame meal (P< 0.05). Weight, relative weight, volume, percentage of phosphorus and calcium of tibia in treatment with 50% sesame meal were significantly higher (P< 0.05). Inclusion of phytase enzyme led to an increase in percentage of spleen, density, percentage of ash, percentage of calcium and phosphorus of tibia(P< 0.05).Treatment of 50% sesame meal with phytase enzymes had the highest percentage of thigh compared to treatment without sesame meal and without phytase enzymes (P< 0.05). Percentage of phosphorus of tibia in treatments of that 25% and 50% sesame meal with phytase were higher compared to other treatments (P< 0.05). According to the results of this study that 25% and 50% sesame meal can be used in Japanese quail’s diets, without any negative effect on performance, carcass characteristics and tibia characteristics.
