First, duck suitable breeding age
The age of duck breeding is not easy to be premature, and the mating age is too early, which not only has adverse effects on its own growth and development, but also has a low fertilization rate. General egg-type ducks were sexually mature earlier, and the initial age was more than 5 months old; meat-type ducks were sexually mature later, and the initial age was more than 6 months.
Second, the proportion of male and female collocation
The breeding performance of ducks varies greatly depending on the type of breed. Generally, the appropriate ratio of male to female is 1:2-25 for egg-type ducklings, 1:15-20 for ducks for combined use, and 1:5-8 for meat-type ducks.
Third, other factors that affect duck breeding performance
In addition to the breeding ratio and species type, the mating performance is also affected by the following factors, and farmers can make appropriate adjustments according to their feeding needs.
Fourth, feeding and management factors
Under good husbandry conditions, especially for grazing ducks, due to the availability of rich animal feed, the breeding performance is enhanced. Therefore, the proportion of male ducks can be reduced appropriately.
V. Seasonal factors
In early spring, the climate is cold and ducks are affected by sexual activity. The proportion of male ducks should be increased by about 2% (based on the number of female ducks).
Sixth, the time between male and female gregarious factors
Prior to the breeding season, appropriate early horticulture can increase fertility in female ducks. The proportion of male ducks at the beginning of the gregarious period may be slightly higher. For example, the male to female ratio of egg-type ducks may be 1:14 to 16; after 20 days, it may be changed to 1:25. Therefore, the male duck should be put into the mother duck group as early as possible in large group breeding.
VII. The Age of Breeding Ducks
Ducks are typically about 1 year old and have a strong sexual desire. Therefore, the proportion of the duck population can be reduced appropriately.
