The study aims to determine suitable feeding rates for NTP2 young breeders muscovy ducks (9-24 weeks) and was surveyed from Aug, 2020 to Mar,2022 in the Thuy Phuong Poultry Reseach Center. Feeding rates were based on Grimaud Frères‘s recommendation for roof D and were arran-ged into 3 treatments, corresponding to the feeding rate 95, 100 and 105% of the feeding rate of D female. The results showed that all feeding rates did not affect the survival rates. Body weight at the 10 weeks of age was considerable difference: NT1 is 1,878.19, NT2, NT3 are 1,936.89 and 1,979.03g, respectively. Body weight at 24 weeks of age of 3 treatments reached 2,408.60, 2,510.15; 2,611.46g, respectively. Age at laying at 5% laying rate also increased gradually as the food intake increased, from treatment 1 to treatment 3 reached the values of 2,587.50, 2,637.50, 2,698.33g, re-spectively. Conversely, the higher the feeding rate, the lower the age to lay 5% of laying rate, and from the treatment 1 to treatment 3 were 197, 192, 188 days, respectively. Egg production, feed con-sumption/10 eggs were statistically significant increases with values from treatment 1 to treatment 3 of 148.46, 150.39, 146.37 egg/hen; 4.44, 4.26, 4.66kg, respectively. There wasn‘t significant differen-ce in hatching criteria between the 3 treatments, the fertilized eggs ranges from 93.29-95.01% and 80.01-81.35% hatching rate/total egg input, 85.44-86.04% hatching rate/fertilized egg.
