Natural mating is a method of mating male and female ducks in a watery environment. The mating season is generally from February to June each year, that is, from the beginning of spring to the end of the summer solstice.
Natural mating and mating methods
Ducks are naturally bred with large groups of breeding and small group breeding in two ways:
Large groups of breeding breeds male and female ducks in a certain proportion. The size of the group depends on the size of the duck population and the area of ​​the breeding environment. Generally, ponds, rivers, and lakes are used to allow ducks to play and mate. This method can make every duck have the opportunity to mating freely with the female duck, the fertility rate is higher, especially the grazing duck group fertilization rate is higher, suitable for reproductive production groups. However, it should be noted that the age and constitution of the breeder must be similar, and the poorer physique and the older male breeder do not have the ability to compete, and should not be used for large group breeding. In large group breeding, it is often seen that part of the male duck does not disperse in the female duck group for breeding for a long period of time, and it takes more than ten days to mate. Therefore, it is necessary to put the duck into the mother duck group early in the large group breeding.
Small Breeding Breeding Each male duck and its responsible breeding females are reared in a single room so that each male breeds with the designated female ducks. A water barrier is set in each breeding stall to enable the ducks to mate. Both the male and the female ducks have their feet numbered. Each female duck lays eggs at a fixed laying nest at night, and the ducklings record the male and female duck feet. This method can determine the parents of ducklings and is suitable for breeding ducks. It is a common method in duck farms.
Breeding age
Early ageing of ducks not only has adverse effects on their own growth and development, but also has a low fertility rate. General egg-type ducks were sexually mature earlier, and the initial age was appropriate for 5 months of age; meat-type ducks were sexually mature later, and the initial age was 6 months. Breeding ratio
The ratio of breedability of ducks differs greatly depending on the breed type. The ratio of male to female is generally 1:20 to 1:25 for egg-type ducks, 1:15 to 1:20 for concurrent ducks, and meat-type ducks. It is 1:5~1:8.
In addition to the variety of species, the proportion of breeding is affected by the following factors.
The climate is cold in early spring, and sexual activity is affected. Ducks should be increased by about 2% (based on the number of female ducks).
Feeding and management conditions The number of male ducks can be reduced appropriately under good husbandry conditions, especially when grazing ducks can obtain abundant animal feed.
The length of the male and female ducks' gregarious time Before the breeding season arrives, it is advantageous to raise the fertilization rate as early as possible. The proportion of male ducks in the early part of the group may be slightly higher. For example, the male to female ratio for egg-type ducks may be 1:14 to 1:16, and may be changed to 1:25 after 20 days. In large group breeding, it is often seen that part of the male duck does not disperse in the female duck group for breeding for a long period of time, and it takes more than ten days to mate. Therefore, it is necessary to put the duck into the mother duck group early in the large group breeding.
Ducks of one-year-old breeders have a strong libido, and the number of ducks can be reduced appropriately.
Practice has shown that too many ducks often result in low fertility. It was determined that egg-type ducks were bred at 1:10, the fertilization rate was only 64.9%, and the fertilization rate was 92.5% when they were bred at 1:25. This is because too many ducks are prone to match and interfere with normal breeding.
