Abstract:

This experiment was conducted to evaluate the effects of dietary riboflavin levels on growth performance, antioxidant capacity and hormone secretion of Peking ducks from 1 to 21 days of age. Using a one-factor completely randomize design, a total of 512 one-day-old male Peking ducks were randomly divided into 8 groups with 8 replicates in each group and 8 ducks in each replicate. Eight groups were fed eight dietary riboflavin levels (1.69, 2.39, 3.09, 3.79, 4.49, 5.19, 8.69, 15.69 mg·kg-1) diet, respectively. The growth performance were determined. The results showed that dietary riboflavin levels significant affected average daily weight gain, average daily feed intake and feed/gain (P<0.05); dietary riboflavin levels significant affected MDA and SOD in plasma and liver(P<0.05); dietary riboflavin levels significant affected plasma T3 and GH content (P<0.05). Riboflavin was essential for growth of Peking duck from 1 to 21 days of age.
