Abstract

This experiment was conducted to determine the effects of a probiotic (Yeasture®) at different rearing stages on intestinal microflora and blood biochemical parameter in broiler chickens. A total of 378 one day old, male and female (Ross 308) broiler chicken were randomly allocated to one of the 21 floor pens in a completely randomized design with seven treatments and three replicate groups and eighteen chicks in each group (9 male and 9 female). Experimental treatments consisted of seven groups, including: A (control), B (1-11 days), C (1-24 days), D (1-42 days), E (11-24 days), F (11-42 days) and G (24-42 days). The results of this study indicated that probiotic at different rearing period in the diet significantly increased blood glucose and calcium during the whole period and significantly decreased blood cholesterol, low density lipoprotein (LDL) and uric acid. In addition, probiotic in diets at different rearing stage had a significant effect on Bifidobacterium and total aerobic bacteria counts. Gender and treatment interaction had no significant effect on the intestinal microflora population. Blood cholesterol and triglyceride levels were significantly lower in male broilers than female broilers. It is concluded that Yeasture® at whole rearing period (1-42 days) in diets improved intestinal microflora population and blood metabolites in broiler chickens.
