Studies of Influence of Dietary Lysine and Methionine Levels on Protein Deposition and Feather Growth of Pheasants
A trial with 2 factors quadratic regression right cross design were conducted to study the influence of dietary lysine (Lys) and methionine (Met) levels on protein deposition of 1-day to 8 weeks old young ring-necked pheasants and feather growth of 8th and 16th weeks ages. The results show as follows: Both Lys and Met could influence significantly the protein deposition of carcass, feather and body of pheasants in quadratic. The optimal dietary Lys (1.284%) and Met (0.511%) lever with the largest protein deposition of feather is larger that with the largest protein deposition of carcass and dietary protein net utilization ratio. The feather growth is the best with 1.260% Lys and 0.634% Met from 0 to 8 weeks or with 0.751% Lys and 0.410% Met from 9 to 16 weeks.
