Abstract

This experiment was conducted to investigate the effects of diets supplemented with glucose oxidase (GOD) on growth performance, serum parameters and slaughter performance of meat ducks and its antidotal effect on aflatoxin B₁. A total of 100 Cherry Valley ducks (1-day-old) were randomly assigned to five groups with four replicates of fifty ducks in each replicate. The control group (group Ⅰ) was fed on a basic diet. The two test groups (groups Ⅱ and Ⅲ) were fed on basic diet supplelemted with 100 and 200 g/t GOD. Aflatoxin B₁ control group (group Ⅳ) was fed on basic diet with moldy corn. The group Ⅴ was fed on the contaminated diet with 200 g/t GOD. The experiment lasted for 46 days. The results showed as follows: 1) the average daily gain and ratio of feed to gain of ducks in groups Ⅱ and Ⅲ were significantly better than those in the control group (P<0.05). Compared with the group Ⅳ, the average daily gain in group Ⅴ was significantly improved (P<0.05). The mortality in group Ⅳ was significantly higher than that in other groups (P<0.05). 2) The serum glucose content in group Ⅳ was significantly lower than that in groups Ⅱ, Ⅲ and Ⅴ (P<0.05), the serum thyroid-stimulating hormone content in group Ⅳ was significantly lower than that in control group (P<0.05), the serum growth hormone content in groups Ⅲ and Ⅴ was significantly higher than that in other groups (P<0.05). 3) The percentage of eviscerated yield and percentage of breast muscle of ducks in group Ⅳ was significantly lower than that in other groups (P<0.05). The percentage of leg muscle of ducks in group Ⅳ was significantly lower than other groups (P<0.05), but no significant difference with control group (P>0.05). The experiment indicated that the growth performance of ducks fed on basic diet can be significantly improved by supplementing GOD. The growth performance, serum parameters, slaughter performance and mortality rate of ducks fed diet with aflatoxin B₁ can be improved by supplementing GOD.
