Artificial insemination method for female cherry valley ducks

Abstract

The invention discloses an artificial insemination method for female cherry valley ducks, which is characterized in that the cloaca of a female duck contracts tightly and is difficult to turn out, the lower edge of the cloaca is slightly extruded by three fingers of the left hand and the right hand, and the cloaca opening is slightly pushed aside by the index finger, so that the cloaca is opened, the tension of the female duck is reduced, and the cloaca of the female duck is convenient to open; when a male duck is inseminated, the forefinger of the right hand is slightly and slowly inserted into the cloaca from the cloaca opening, then the vaginal opening is found from the left lower side, the vaginal opening of the female duck can be better found, the number of effective sperms fed is 50 million to 90 million, sufficient insemination amount is fed, the fertilization rate of seminal fluid insemination of the male duck is high, the insemination amount can be increased by one time during first insemination, or insemination is repeated once the next day, the good fertilization rate can be maintained by conducting insemination once every 3-4 days, the fertilization rate can be greatly improved by controlling the insemination time, insemination eggs can be conveniently laid, and the problems that the artificial insemination technology for breeding the cherry valley breeding ducks is poor, and the probability of increasing the yield of the insemination eggs is low are solved.

Description

technical field [0001] The invention relates to the technical field of artificial insemination of breeding ducks, in particular to an artificial insemination method for female Cherry Valley breeding ducks. Background technique [0002] Duck, chordate phylum, vertebrate subphylum, bird class Anasteriformes, Anatidae Anatidae animals, domesticated from wild mallard ducks and spot-billed ducks, is a common poultry, ducks are Anatidae Anatidae A collective name for waterfowl of the subfamily Duck. Can stay in the water, but can't stay in the water for too long, it is an oviparous animal, [0003] The process of breeding ducks in Cherry Valley requires artificial insemination to obtain more insemination rate, increase the probability of producing fertilized eggs, increase the income of farmers, and also contribute to the breeding cause of our country. For this reason, we designed a An artificial insemination method for female Cherry Valley ducks. Contents of the invention ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the present invention provides a method for artificial insemination of female Cherry Valley ducks, which solves the problem that the artificial insemination technology in the breeding of Cherry Valley ducks is poor and the probability of increasing the output of fertilized eggs is not high
