CN104885993A - Artificial insemination method for breeding chicken - Google Patents

Abstract

The invention discloses an artificial insemination method for a breeding chicken. The method comprises the following specific steps: collection of a seminal fluid and dilution of the seminal fluid: normal saline with the volume being 2 times that of the seminal fluid or a 5.7% glucose solution is slowly added into a sperm collection test tube along the wall of the sperm collection test tube; the sperm collecting test tube is slightly rotated repeatedly for 3-4 times; artificial insemination: after 3:00 pm, an anus turning worker turns over the anus of a hen, and a sperm conveying worker transfers the diluted seminal fluid into the seminiferous duct, slightly inserts the seminiferous duct into the oviduct of the hen and conveys the seminal fluid into a conveying tube. The method has the advantages of high fertilization rate and the like.

Description

A kind chicken artificial insemination method

Technical field

The present invention specifically relates to a kind chicken artificial insemination method, is applied to the cultivation field of poultry.

Background technology

In China; chicken and egg very popular, therefore the demand of chicken and egg is larger, accordingly; the chicken raising factory of China is also just many; and along with the continuous progress in epoch, poultry husbandry scale gradually, intensive, at present; technology of artificial insemination has been widely used in the production of kind of chicken; but existing technology of artificial insemination is relatively backward, and fertilization rate is lower.

Summary of the invention

For solving the defect of prior art, the invention discloses the kind chicken artificial insemination method that a kind of fertilization rate is high.

The invention discloses a kind chicken artificial insemination method, concrete steps are as follows:

Step one: collecting semen: under quiet environment, feather around stock cock cloaca is cut off, the diameter of exposed area is 4-5cm, then collector catches stock cock, before Caudad, head backward, stock cock is fixed on the oxter of collector, two legs are nature stances, collector is clipped in the smart cup of collection in the middle of the right hand and the third finger, rim of a cup outwardly with the back of the hand in the same way, left hand thumb and four refers to separate, be attached to inside the wing of both sides, stock cock back, rearwardly massage slip 2-3 time is gently held up in region, hand thumb and four refers to separate the belly of massaging phalanx lower edge from down to up gently simultaneously, when the mating device of stock cock turns up, left-handed forefinger and thumb are mentioned mating device and are extruded mating device, the smart cup of right hand reversing collection accesses cloaca seminal fluid, immediately in shift-in collection essence test tube,

Step 2: dilution seminal fluid: use the physiological saline of 2 times of ejaculate volume or the glucose solution of 5.7% slowly to join collection essence in vitro along the smart test tube tube wall of collection, then rotate the smart test tube of collection gently, repeat 3-4 time;

Step 3: artificial insemination: in the afternoon after 3:00, turn over anus person and anus is turned over to hen, seminal fluid after dilution is transferred in vas deferens by semen deposition person, then semen deposition person vas deferens is inserted gently hen oviduct in and the seminal fluid in vas deferens is transported in carrier pipe.

Of the present invention kind of chicken artificial insemination method, by the collection to stock cock seminal fluid, the even dilution to seminal fluid and the artificial insemination in later stage, effectively can improve fertilization rate, and can not cause the inflammation of hen oviduct or the generation of bleeding.

Embodiment

The invention discloses a kind chicken artificial insemination method, concrete steps are as follows:

Step one: collecting semen: under quiet environment, feather around stock cock cloaca is cut off, the diameter of exposed area is 4-5cm, chicken manure can be prevented like this, feather bits or dust drop into the pollution causing seminal fluid in semen collection cup, thus the defect causing fertilization rate low, then collector catches stock cock, before Caudad, head backward, stock cock is fixed on the oxter of collector, two legs are nature stances, collector is clipped in the smart cup of collection in the middle of the right hand and the third finger, rim of a cup outwardly with the back of the hand in the same way, left hand thumb and four refers to separate, be attached to inside the wing of both sides, stock cock back, rearwardly massage slip 2-3 time is gently held up in region, stock cock can be made like this to form normal sexual reflex, be beneficial to and produce essence, hand thumb and four refers to separate the belly of massaging phalanx lower edge from down to up gently simultaneously, when the mating device of stock cock turns up, left-handed forefinger and thumb are mentioned mating device and are extruded mating device, the smart cup of right hand reversing collection accesses cloaca seminal fluid, immediately in shift-in collection essence test tube,

Step 2: dilution seminal fluid: use the physiological saline of 2 times of ejaculate volume or the glucose solution of 5.7% slowly to join collection essence in vitro along the smart test tube tube wall of collection, then the smart test tube of collection is rotated gently, repeat 3-4 time, can make like this physiological saline or 5.7% glucose solution fully mix with seminal fluid, dilution effect improves greatly, is beneficial to the raising of fertilization rate;

Step 3: artificial insemination: because in the afternoon after 3:00, the egg meeting output of hen, therefore in the afternoon after 3:00, turn over anus person and can turn over anus to hen, seminal fluid after dilution is transferred in vas deferens by semen deposition person, then semen deposition person vas deferens is inserted gently hen oviduct in and the seminal fluid in vas deferens is transported in carrier pipe, so both can reach the object of semen deposition, and can effectively prevent vas deferens from puncturing tubal wall, and cause oviducal inflammation or hemorrhage.

Embodiment 1
