    abstract = {The 480, 1 day old male Cherry Valley ducks were randomly 
  allocated into three groups for a 42 days feeding trial including 1-21 and 22-42 
  days period. Dietary CP percentage in experimental diets (g/kg) were 21, 20 
  and 19% for groups I, II, III, respectively. Results showed that 1-21 days: 
  the feed intake and body weight gain in group II and III was higher (p<0.01) 
  than group I the feed conversion ratio of group II was lower (p<0.05) than 
  group I; the serum total protein in group I was higher (p<0.05) than group 
  III, 0.22-42 days: the feed conversion ratio of group III was lower (p<0.05) 
  than group II; the breast muscle ratio of the group II was increased (p<0.05) 
  by 7.53% than group I; the leg muscle ratio of the group I was increased (p<0.05) 
  by 7.57% than group III; the GSH-PX of group II and III was higher (p<0.05) 
  than group I by increased 16.50 and 17.21%, respectively. In conclusion, a dietary 
  CP level of 20% was optimal in terms of growth performance and reduced nitrogen 
  excretion.}
