Abstract

Probiotics and aflatoxin B₁ (AFB₁) degrading enzyme were combined to make detoxificating materials for determining its effects on growth performance of broilers and its mechanisms. A total of 200 one-day-old Arbor Acres (AA) broilers were randomly allocated to 5 groups with 5 replicates per group and 8 broilers per replicate. Broilers in group A (control group) were fed a basal diet, broilers in groups B (negative control group), C, D and E were fed the basal diet containing 100 μg/kg AFBl, and supplemented with 0, 0.05%, 0.10% and 0.15% probiotics and AFB₁ degrading enzyme, respectively. The experiment lasted for 21 days. The results showed that compared with group B, the average daily gain, nutrient metabolic rates and caecum lactic acid bacteria number were increased, and mortality rate and diarrhea rate were significantly decreased in the groups added with probiotics and AFB₁ degrading enzyme (P<0.05). Adding 0.15% probiotics and AFB₁ degrading enzyme could decrease the serum low-density lipoprotein content, while increase the indirect bilirubin content, glutamyltransferase activity and total anti-oxidation ability (P<0.05). It is concluded that the combination of probiotics and AFB₁-degrading enzyme can decrease the negative effect of high dietary AFB₁ concentration on growth performance of broilers.

Key words： aflatoxin B₁; probiotics; detoxificating enzyme; broilers; growth performance
