  • The effects of dietary energy, protein and methionine level on laying performance of egg-laying duck (Putian Black Duck) wree studied. The energy levels ranged in 2500-2750 kCalM·E/kg, They did not affect significantly on laying performance. The optimum energy level was 2600 kCalM·E/kg. In a certain range, the laying performance increase with the rising of dietary protein and methionine levels. When the daily intake of protein and methionine was 29 g and 493 mg respectively, the laying performance showed the best. Ideal reproducibijity was obtained in the triplicate experiments.
