The effect of Feeding Diets Containing Toyocerin Probiotic on Broiler Chicks Performance and Internal Organs Weight

The effects of dietary supplementation of a probiotic Toyocerinon performance and internal organs weight of broiler chicks were investigated. In a completely randomized block design, three hundred and fifteen of one-day-old broiler chicks (Rose) were assigned to seven treatments with three replicates of 15 chicks in the experimental unit. The experimental Toyocerin treatments were added to basal diets at different levels of 0, 20, 40, 60, 80, 120 and 120 g/100Kg of diet and denoted as A1, A2, A3, A4, A5, A6, and A7 respectively. Regarding performance parameters total body weight, daily body gain weight, feed intake, and feed conversion ratio. There was a significant difference between treatments for total body weight and daily gain weight. Although an improvement in the feed intake and feed conversion ratio was observed but failed to be statistically significant. In this study, the organs weights such as heart, liver, spleen, proventriculus, gizzard, bursa fabricius, small intestine, large intestine, pancreas, and duodenum were determined. Significant differences (p<0.01), in weight, were observed for all between groups supplemented with Tyocerin and the control group. Results indicated that consumption of Toyocerin had the most positive effect on performance and internal organs weight which indicates that Tyocerin can be used successfully as a supplement to the diet of broilers. It helps in improving the performance and health of the broiler chicks .
