Abstract

 This study is going to investigate the effect of Aquablend Avian probiotic including Lactobacillus, Streptococcus and Bifidobacterium on feed conversion ratio and blood lipids. For this purpose, a total of 180 day-old broiler chicks were purchased and divided randomly into 3 groups. Chickens of group A and B received 300 mg of probiotic per 60 birds for 3 days and 7 days respectively in drinking water at the first of period. Chickens of group C were kept as control group and did not receive probiotic. In order to determination total serum cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, and triglyceride using the Commercial Kits, blood samples were collected from 10 chicks of each group at the end of experiment. Average of feed intake, weight gains, feed conversion ratio of 3 groups were determined at 21, and 42 days.  The results of present study showed that receiving of the probiotic for 7 days, significantly increased total serum cholesterol compared to the control group and significantly increased HDL compared to the group A. There is no significant difference between groups about LDL and triglyceride
