White feather male domestic ducks D,CD and B hybridized with femal white feather muscovy duck M , and three groups of mule ducks DM, CDM and BM were obtained.Compare the ducks with control groups MD,MCD and MB:The ratio of 1~3 classes of white feather were same respectively.The differences of eviscerated weight with giblet, lean and skin fat rate were not significant;the body weights 8 and 10 week age were lighter, the percentage of breast muscle yield was high, the differences of both were significant.The mule duck’s growth speed was rather slow and the daily gain would decline quickly at 8-10 weed age, the breast growth shows early maturity.The differences of the body weight between the male and female of the mule duck was disparate, the female’s bedy weight at 10 week age was about 59% of the male’s and the incubation period of the mule duck is 31-32 days,it shows dam’s(female muscovy) genetic Character.The mule ducks have laying ability.The first egg of the mule duck is at 28 week age.The laying peak is at 32 week age and the laying rate is 74%.The egg number in 42 week age averages 54.4,and the averaged egg weight was 50 grams without great change in the all laying period.
