The investigation of a vitamin C and aspirin combination effect on the performance of broiler turkeys and economic analysis of the rearing period

This experiment was conducted to investigate the effect of using vitamin C and aspirin on the performance of broiler turkeys during different weeks, the European performance efficiency factor, and economic analysis of the rearing period in normal conditions.288 male turkey chickens, BUT6 strain, were used as a 3×3 factorial experiment (three levels of 0, 250, and 500 mg/kg vitamin C, and three levels of 0, 75, and 150 mg/kg aspirin) ina completely randomized design with nine experimental groups, 4 replications and 8 birds per replication. The results showed that vitamin C and aspirin have no effect on body weight, daily weight gain, feed intake, and feed conversion ratio of broiler turkeys during different weeks of rearing (P>0.05). However, only in the ninth week of rearing, chickens fed the combination of aspirin and vitamin C in levels of 75 and 250 mg/kg showed a higher daily weight gain than the control group (P<0.05). The feed conversion ratio of chickens in this group was lower than that in other groups in the ninth week (P<0.05). On the other hand, the European performance efficiency factor was not affected by the experimental groups. Economic analysis of the rearing period showed that vitamin C and aspirin supplementation have no effect on total feed cost/bird, feed cost/Kg body weight, sale bird, and net return. In conclusion, the use of vitamin C and aspirin does not recommend in turkey chickens under normal conditions.
