Embodiment Construction

[0012] Such as figure 1 As shown, the F1 generation is produced by crossing the cock (silver feather) of the silver pigeon with the hen (gray feather) of the Texen pigeon. In the F1 generation, only two feather colors are separated, and the gray feather is the male. Pigeons, the ones with silver feathers are hens.

[0013] There are no gray hens and silver cocks in the F1 generation.

[0014] After selfing with the F1 male and female pigeons, the F2 generation cannot be distinguished by feather color. The F1 generation hens lay 0.27-1.14 eggs per pair per month higher than the Texen hens and the Silver King pigeons.

[0015] This kind of pigeon can realize early male and female identification through the difference of plumage color at the age of 12 days, so that male pigeons can be eliminated as soon as possible and sold as meat pigeons, and the hens can be cultivated to lay eggs for laying pigeons, saving a lot of feeding costs.

[0016] This breed of pigeons can directly ...

Abstract

The invention relates to a breeding method of feather color automatic sexing laying pigeons, and belongs to the technical field of animal breeding. Hybridization is conducted on male pigeons (silver feather) in silver king pigeons and female pigeons (gray feather) in Thaxon pigeons to produce the generation F1, two types of feather colors are separated from the generation F1, the male pigeons have the gray feather color, the female pigeons have the silver feather color, the accuracy can reach 100%, and no female pigeons with the gray feather color or male pigeons with the silver feather color can appear in the generation F1. After selfing is conducted on the male pigeons and the female pigeons in the generation F1, color sexing can not be conducted. The egg yield (6.27 eggs or pairs of eggs per month) of female pigeons in the generation F1 is higher than the egg yield (5.13 eggs or pairs of eggs per month) of Thaxon pigeons and the egg yield (6 eggs or pairs of eggs per month) of silver king pigeons. Male bred laying pigeons and female bred laying pigeons can be recognized in the early stage according to the difference of feather colors, lots of breeding cost can be saved, no recognizing cost is needed, the accuracy can reach 100%, and the egg laying performance is better than that of Thaxon pigeons and silver king pigeons.

Description

technical field [0001] The invention relates to a method for breeding male and female laying pigeons with different feather colors, and belongs to the technical field of animal breeding. Background technique [0002] In the process of pigeon breeding, because the external sexual characteristics of male and female pigeons are not obvious, the early identification of male and female has always been a difficult problem for practitioners. Simply producing pigeon eggs is more profitable than producing pigeons, which directly leads to the production of egg pigeons. This just needs to identify male and female around the age of 28 days, eliminate male pigeons, and leave hens to lay eggs. At present, most of the male and female identifications are made after the breeding pigeons are sexually mature and the external sexual characteristics are fully developed, and the male and female are identified according to their body shape and appearance. Only 80-90%. With the advancement of sc...
