Abstract

This experiment was conducted to study the effects of dietary threonine (Thr) level on growth performances, immune organ indexes, serum biochemical and antioxidant indices of Youxian partridge ducks aged from 3 to 8 weeks, so as to determine the threonine requirement of Youxian partridge ducks aged from 3 to 8 weeks. Three hundred 15-day-old Youxian partridge ducks with similar body weight were randomly divided into 5 groups with 6 replicates in each group and 10 ducks in each replicate. The dietary threonine levels of five groups (groups Ⅰ to Ⅴ) were 0.54%, 0.60%, 0.66%, 0.72% and 0.78%, respectively The experimental lasted for 42 days. The results showed as followed:1) the final weight and average daily gain of groups Ⅱ, Ⅲ and Ⅳ were significantly higher than those of groupⅠ (P<0.05); the feed to gain ratio of group Ⅰ was the highest, and significantly higher than that of other groups (P<0.05). 2) There were no significant differences in bursa of Fabricius index, spleen index and thymus index among all groups (P>0.05). 3) The serum globulin content of groups Ⅲ and Ⅳ was significantly higher than that of group Ⅰ (P<0.05). The of serum uric acid content of group Ⅳ was the lowest, and significantly lower than that of groups Ⅰ and Ⅱ (P<0.05). 4) The serum malondialdehyde content of groups Ⅲ and Ⅳ was significantly lower than that of group Ⅰ (P<0.05), and the serum total antioxidant capacity of groups Ⅲ, Ⅳ and Ⅴ was significantly higher than that of group Ⅰ (P<0.05). 5) The optimal level of threonine in diets was 0.68%, 0.69%, 0.69% and 0.71% based on final weight, average daily gain, feed to gain ratio and serum malondialdehyde content by quadratic regression, respectively. In conclusion, the dietary threonine level of 0.60% can meet the growth and development requirement of Youxian partridge ducks aged from 3 to 8 weeks, but dietary threonine level of 0.68% to 0.71% can obtain better growth performances, serum biochemical indices and antioxidant capacity. Therefore, in this experiments the dietary suitable threonine level of Youxian partridge ducks aged from 3 to 8 weeks is 0.68% to 0.71%.

Key words： threonine; Youxian partridge ducks; immune function; antioxidant indices
