There are many factors that affect the breeding performance of ducks, such as mating age, male-female ratio, season, and feeding conditions.
Duck suitable breeding age
The age of ducks should not be too early and the mating age is too early, which not only has adverse effects on their 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.
Male to female collocation ratio
The breeding performance of ducks differs greatly depending on the species type. Generally, the appropriate male-female mix ratio is 1:2-25 for egg-type ducks, 1:15-20 for dual-use ducks, and 1: for meat-type ducks. 5-8.
Duck age factor
Ducks are typically about 1 year old and have a strong sexual desire. Therefore, the proportion of the duck population can be reduced appropriately.
Feeding 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.
Male and female gregarious time factor
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 for egg-type ducks may be 1:14-16; 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.
other factors
In addition to factors such as breeding proportion and species type, breeding performance is also affected by other factors. Farmers can make appropriate adjustments according to feeding requirements.
