Embodiment 1

[0018] (1) For domestic ducks from the age of 180 days, artificial supplementary light is given for 40 consecutive days, 15 hours a day. The artificial supplementary light is provided with 1 LED light source per 20 square meters under the conditions of house feeding or half house feeding, and the color temperature range is 5800K; start collecting sperm at 220 days old;

[0019] (2) A week before domestic duck semen collection, add 29IU of vitamin E per kilogram of feed, adjust the crude protein to 18%, supply vitamin A and vitamin C in regular amounts, and maintain the metabolic energy at 19.9MJ / kg;

[0020] (3) The semen collection time is scheduled at 9 o'clock in the morning in the spring. The semen collected from 3 feathers is mixed with 5% glucose and semen 1:1, and then 1ml mixture is added with 3000IU penicillin (0.1-0.3mg / ml) After adding, mix well, dilute and mix well and mix the semen within 20 minutes;

[0021] (4) Use anal insemination, squeeze the cloaca to drain the fe...

Embodiment 2

[0024] (1) For domestic ducks from the age of 180 days, artificial supplementary light will be given for 20 consecutive days, 15 hours a day. The artificial supplementary light is provided with 1 LED light source per 20 square meters under the conditions of house feeding or half house feeding, and the color temperature range is 5500K; 200 days old to start collecting sperm;

[0025] (2) A week before domestic duck semen collection, add 25IU of vitamin E per kilogram of feed, adjust the crude protein to 17%, supply vitamin A and vitamin C in regular amounts, and maintain the metabolic energy at 19.9MJ / kg;

[0026] (3) The semen collection time is scheduled at 10 o'clock in the morning in the autumn. The semen collected from 3 feathers is mixed with normal saline and semen 1:1, then add 3000IU streptomycin (0.3-0.5mg / ml) according to 1ml mixture. ) Add and mix well, dilute and mix well, and finish transfusion within 20 minutes;

[0027] (4) Use anal insemination, squeeze the cloaca to...

Embodiment 3

[0030] (1) For domestic ducks from 170 days of age, artificial supplementary light is given for 20 consecutive days, 12 hours a day. The artificial supplementary light is provided with 1 LED light source per 20 square meters under the conditions of house feeding or half house feeding, and the color temperature range is 5800K; summer domestic ducks start collecting sperm from 190 days old;

[0031] (2) A week before domestic duck semen collection, add 25IU of vitamin E per kilogram of feed, increase the crude protein to 17%, supply vitamin A and vitamin C in regular amounts, and maintain the metabolic energy at 19.9MJ / kg;

[0032] (3) The semen collection time is arranged at 4 pm in summer to avoid the high temperature. The semen collected from 4 feathers will be mixed 1:1 with 5% glucose and normal saline, and then mixed with semen 1:1. Then add 3000IU gentamicin (0.05-0.1mg / ml) to 1ml of the mixture and mix well. After diluting and mixing, the semen will be infused within 20 minut...

Abstract

The invention discloses an artificial insemination method for increasing the fertilization rate of domestic duck hatching eggs. The method includes the specific steps that firstly, artificial light supplementation is conducted continuously for 20-40 days on domestic ducks 170-180 days old, artificial light supplementation is conducted for 12-15 h every day, and semen collection is conducted on domestic ducks 190-220 days old; secondly, the content of vitamin E and crude protein in ration is increased one week before semen collection of male muscovy ducks, vitamin A and vitamin C are supplied according to the conventional amount, and metabolic energy is maintained to be 19.0 MJ / kg-20.5 MJ / kg; thirdly, semen collection is conducted between 9 o'clock and 10 o'clock in the morning in spring, autumn and winter and conducted between 4 o'clock and 5 o'clock in the afternoon in summer, semen collection is conducted every two days, semen collection is continuously conducted for 3 days and stops for 1 day, and semen collected every time after 3-5 feathers is diluted, evenly mixed and subjected to insemination within 20 min. According to the method, by means of artificial supplementation of light with the color temperature of 5500-5800 K for the domestic ducks, the nutrient controlling technology of adding vitamin E, crude protein and the like to feed, and the comprehensive technology of semen mixing, semen insemination and environment temperature and semen insemination frequency control, the fertilization rate in domestic duck production is increased.

Description

Technical field [0001] The invention relates to the technical field of poultry breeding, in particular to an artificial insemination method for improving the fertilization rate of domestic duck breeding eggs. Background technique [0002] In recent years, with the rapid development of duck industry, artificial insemination of ducks has received more and more attention. Compared with natural mating, the use of artificial insemination technology in breeding duck production can reduce the number of breeding male ducks and save production costs; improve the utilization rate of excellent breeding male ducks; help prevent the mutual spread of diseases between male and female ducks ; The use of artificial insemination combined with cage breeding of breeding ducks can make the breeding eggs clean, reduce pollution, reduce the damage of the breeding eggs, and improve the qualification rate, fertilization rate and hatching rate of the breeding eggs. [0003] In the field of artificial insem...
