Effects of bentonite and wheat starch on performance, carcass characteristics, blood parameters ilium microbial population in broilers

To consider the effect of supplementation bentonite and wheat starch on performance, carcass characteristics, blood parameters and value pH of gastrointestinal tract and litter and ilium microbial population intestinal morphology characteristics of broilers, a completely randomized design test was done with four treatments and five replicate for each treatment. In this experimental Two hundred one day-old mixed sex broilers (Ross breed) were divided into four treatments with 10 chicks per each replicate (pen). Treatments were contain: 1- Basal diet without additive (control) 2- 2- Basal diet plus bentonite 3- Basal diet plus wheat starch 4- Basal diet plus bentonite and wheat starch. The diets were fed to broilers at 42 days and water and feed were fed ad-libitum. Range of feed intake and gain of each replicate were weighted weekly and took blood to determine blood parameters from wing vein of birds. The results showed no significant difference between the experimental groups on gain body and feed conversion ratio but in starter period significantly affect feed intake. Addition of bentonite and wheat starch to diet had not significant effect carcass characteristics. The result of this experiment showed during the whole period of experiment, using bentonite and wheat starch no had significantly effect on cholesterol, triglyceride and VLDL of serum but effect on glucose serum. Treatments significantly effect on PDI in starter and grower period. Effect Experimental treatments no had significant on microbial population. Result indicated that between treatments no had significant on villi length and villus/crypt ratio but were statistically significant (p < 0.05) villi thickness and level.
