The ratio of male and female ducks in the breeding group plays a decisive role in the fertilization rate of the breeding eggs. Excessive amounts of drakes often compete for spouses and harassment with each other, affecting the energy of male ducks, resulting in reduced breeding power and consuming large amounts of feed. The proportion of male and female ducks is affected by factors such as breed, age, season, feeding management, and breeding methods. In general, ducks use eggs more powerfully than meat ducks. The ratio of female ducks can be larger. Young ducks have stronger breeding power than older males, and the proportion of females can be larger. Male ducks are bred in spring. Stronger, the proportion of female ducks can be larger than in other seasons; when the male ducks are in good nutritional status or in large breeds, the proportion of female ducks can also be larger.
Under normal circumstances, the suitable proportion of male and female ducks is 1:20-1:25 for egg and 1:6-1:10 for dual-use. In practice, observing breeding conditions should also be constantly observed. For example, male ducks compete for spouses and affect mating, indicating that too many ducks should be reduced appropriately. If male ducks chase female ducks for breeding, there is no competition for each other, indicating that the number of male ducks is appropriate; If a female duck chases a male duck, it means that the male duck is lacking or the sexual desire is not prosperous and should be filled in time.
Prior to the hatching of the eggs, fertilization tests should also be performed on the eggs in order to correct the inappropriate proportion of spouses. The method is to randomly select 10 eggs, open the tested duck eggs, observe the ovule attached to the surface of the yolk, the ovule is a round white spot, which is lean; the ovules are large, the inner layer is transparent and the edges are turbid It is a fertilized egg. The fertilization rate of an excellent egg should reach 95% or more.
The purpose of breeding ducks is to obtain commercial eggs. Practice has shown that the stronger the libido of laying ducks, the more eggs are laid. Maintaining a certain number of ducks in commercial ducks can induce “sex†in ducks and promote the sexual function of ducks and ducks, thereby increasing egg production. Ducks should be kept 2%-5% of the ducks, and egg production can be increased by 10%-12% compared to ducks.
