The purpose of this study was to investigate the effect of probiotics, prebiotics and their mixture on growth performance, blood-serum parameters, microbial population and intestinal morphology of turkey poults.
In this experiment, 96 pieces of hybrid meat turkey poults from the age of 60 to 120 days were used. The treatments included the control diet, diets containing probiotics, prebiotics and equal proportions of probiotics and prebiotics. Production traits were measured weekly and at the end of the breeding period, blood sampling and slaughtering were done to check blood-serum parameters, microbial population and intestinal morphology. The results indicated a significant effect of experimental treatments on feed consumption and feed conversion ratio in the entire breeding period (P<0.05). The percentage of carcass yield, the ratio of spleen and bursa of Fabricius weight to live weight increased in the additive consuming treatments compared to the control group, and the fat weight of the abdominal area decreased significantly (P<0.05). Triglyceride and blood cholesterol in the treatments using additives decreased and the amount of white blood cells and blood albumin increased significantly (P<0.05). Additives had a positive effect on the parameters of intestinal morphology and the population of Escherichia coli bacteria in the cecum significantly decreased (P<0.05). Based on the findings of this research, it is recommended to use pro and prebiotics alone and together as a supplement in the feed of turkeys.
