Problems solved by technology

[0005] The above artificial semen collection techniques are mainly studied from male duck semen collection training and semen collection methods. Among them, the massage method has poor semen collection effect, less semen volume and low sperm density; electric stimulation method and false vagina The semen collection method requires the use of special equipment; the ejaculation method of female duck semen collection takes a long time (about 2 minutes for each male duck), and the male duck needs to be caught and released frequently, which causes the stress of the male duck and affects other ducks. Sustainability of semen collection

Embodiment Construction

[0028] The embodiments of the present invention will be described in detail with the following examples, so as to fully understand and implement the implementation process of how to apply technical means to solve technical problems and achieve technical effects of the present invention.

[0029] The invention provides a method for collecting sperm of a male duck, comprising the following steps:

[0030] 1) Selection and seed retention of ducklings: within 1 day of age after hatching of large meat ducks (such as Peking duck) or high-quality hemp-feathered ducks (such as Jianchang duck), use the anus-turning method to identify males and females , according to the male-female ratio of 5:1, that is, the ratio of 5 male ducks and 1 female duck is reserved. The role of female ducks is to make male ducks develop gender recognition.

[0031] 2) Cultivation of young male ducks: The male ducks and female ducks kept for breeding are reared on the ground in mixed groups. From 0 to 21 day...

Abstract

The invention discloses a drake semen collecting method. The drake semen collecting method includes the following steps of selection and breeding duck reserving of ducklings, cultivation of young drakes, regular cage feeding, semen collecting training, implementing of the semen collecting method and nutrition regulation. In the drake semen collecting process, it is not needed to seize the drakes from duck cages, stress of the drakes can be remarkably reduced accordingly, and healthy and sustainable production of the drakes is guaranteed.

Description

technical field [0001] The invention belongs to the field of poultry breeding, in particular to a method for collecting sperm of a male duck. Background technique [0002] China is the largest duck producing, consuming and trading country in the world, and the duck industry ranks first in the world. The duck industry produces meat duck production and laying duck production, and meat duck production includes several types of large white feather meat duck production, small and medium-sized high-quality meat duck production, muscovy duck and mule duck production. Traditionally, ducks in my country are mainly raised in captivity by the pond or stocked in natural waters. The breeding ducks generally adopt the natural mating method, that is, the breeding ducks are placed in a certain proportion of the breeding ducks for breeding. However, with the increasing pressure of environmental protection, many duck breeding modes such as pond breeding and stocking in natural waters have be...
