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.
