Research on suitable raising methods for “Sen” muscovy duck of reproduction
A random factor experiment (raising menthod) was conducted on 1,800 “Sen” muscovy ducks for breeding and was conducted at Dai Xuyen Duck Breeding and Research Center, experimental 1 (completely kept in house), experimental group 2 (kept in house and raising in garden). Starting from 1 day of age, experimental muscovy ducks were wearing the number of wings each, there were two experimental: experimental 1 (completely kept in house) reached 92.89%, experimental group 2 (kept in house and raising in garden). Arranged in the stages of duckling (0 - 8 weeks of age) - prepare laying - laying. The results show that: The survival rate in the stages of duckling and prepare laying (0 - 26 weeks of age), the survival rate achieved from experimental 1 (completely kept in house) reached 92.89%, experimental group 2 (kept in house and raising in garden) reached 91.22%, the body weight of Sen muscovy duck at 26 weeks of age reached in experiment 1 was 3120.50g/male, 2011.67g/female; the weight of experiment 2 was 3052.78 g/male and 1976.17 g/female. At 29 weeks of age, laying rate in 52 weeks was the highest in treatment 1 (kept in house) 24.32%, treatment 2 (kept in house and raising in garden) 23.95%; egg production was 88.54 and 87.18 eggs/female/52 weeks of laying; feed consumption/10 eggs were 6.89 and 6.91 kg respectively, the embryo rate in experiment 1 reached 94.78% and the rate of embryos in experiment 2 reached 94.66%. Percentage of hatched/total eggs with embryos was highest in treatment 1 was 85.58% and treatment 2 reached 85.79%. The ratio of type I duckling / number of ducklings hatched in treatment 1 was 94.80% high and 94.46% in treatment 2. Economic efficiency was 176,642,389 VND, interest /female 392,539 VND, mixed income index (MI), profit (Pr), mixed income / total cost and mixed income / labor reaching the highest level in the experimental lot 1 with the corresponding indices of 239,642,389 VND; 203,642,389 VND; 0.59 and 6.66. Sen muscovy duck completely kept in house.
