Embodiment 1

[0017] (1) From the age of 180 days, shelducks are given artificial supplementary light for 40 consecutive days, 15 hours a day. The artificial supplementary light is provided with one LED lighting source per 20 square meters under the condition of house feeding or semi house feeding, and the color temperature range 5800K; start semen collection at 220 days old;

[0018] (2) Add vitamin E 29IU per kilogram of feed one week before duck semen collection, adjust the crude protein to 18%, supply vitamin A and vitamin C according to the conventional amount, and maintain the metabolic energy at 19.9MJ / kg;

[0019] (3) The semen collection time is arranged at 9:00 in the morning in spring. The semen after harvesting 3 feathers is mixed with 5% glucose and semen 1:1, and then 3000IU penicillin (0.1-0.3mg / ml) is added to 1ml of the mixture. Mix well after adding, dilute and mix well, mix the semen and infuse within 20 minutes;

Embodiment 2

[0023] (1) Starting from the age of 180 days, shelducks are given artificial supplementary light for 20 consecutive days, 15 hours a day. The artificial supplementary light is provided with one LED lighting source per 20 square meters under the condition of house feeding or semi house feeding, and the color temperature range 5500K; start semen collection at 200 days old;

[0024] (2) Add vitamin E 25IU per kilogram of feed one week before duck semen collection, adjust the crude protein to 17%, supply vitamin A and vitamin C according to the conventional amount, and maintain the metabolic energy at 19.9MJ / kg;

[0025] (3) The semen collection time is arranged at 10:00 in the morning in autumn. The semen after harvesting 3 feathers is mixed with normal saline and semen at a ratio of 1:1, and then 1ml of the mixture is added with 3000IU streptomycin (0.3-0.5mg / ml ) was added and mixed evenly, and after dilution and mixing, the semen was transfused within 20 minutes;

Embodiment 3

[0029] (1) From the age of 170 days, shelducks are given artificial supplementary light for 20 consecutive days, 12 hours a day. The artificial supplementary light is provided with one LED lighting source per 20 square meters under the condition of house feeding or half house feeding, and the color temperature range It is 5800K; summer shelducks begin to collect semen from 190 days old;

[0030] (2) Add vitamin E 25IU per kilogram of feed one week before shelduck semen collection, the crude protein is increased to 17%, vitamin A and vitamin C are supplied according to the conventional amount, and the metabolic energy is maintained at 19.9MJ / kg;

[0031] (3) The semen collection time is arranged at 4:00 p.m. in summer to avoid high temperature. The semen after harvesting 4 feathers is mixed with 5% glucose and normal saline at a ratio of 1:1, and then mixed with the semen at a ratio of 1:1, and then Then add 3000IU gentamicin (0.05-0.1mg / ml) to 1ml of the mixed solution and mix...

Abstract

The invention discloses a breeding method for artificially improving the fertilization rate of shelduck duck breeding eggs, which comprises (1) starting from 170 to 180 days old, giving artificial supplementary light to the shelduck for 20 to 40 consecutive days, 12 to 15 hours a day, at 190 to 190 to 180 days. Semen collection began at 220 days old; (2) Increase the vitamin E and crude protein levels in the diet one week before the male Muscovy duck sperm collection, vitamin A and vitamin C were supplied according to the conventional amount, and the metabolic energy was maintained at 19.0MJ / kg-20.5MJ / kg; (3) The timing of semen collection in spring, autumn and winter is 9-10 a.m., and 4-5 p.m. in summer. Semen collection is once every 2 days. The semen after picking 3 to 5 feathers is diluted and mixed and then transfused within 20 minutes; step (1) artificial lighting is to provide 1 LED lighting source per 20 square meters under the condition of house feeding or half house feeding, and the color temperature range is 5500 ‑5800K; Step (2) Add 25-29 IU of vitamin E per kilogram of ration, and adjust the crude protein level to 17.0-18.0%; Step (3) March to May in spring, October to December in autumn and winter.

Description

technical field [0001] The invention relates to the technical field of poultry breeding, in particular to a breeding method for artificially increasing the fertilization rate of shelduck breeding eggs. Background technique [0002] In recent years, with the rapid development of the duck industry, the artificial insemination technology 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 breeding amount of male ducks and save production costs; improve the utilization rate of excellent breeding male ducks; help prevent the mutual transmission of diseases between male and female ducks ;Using artificial insemination combined with breeding duck cages can make the eggs clean, reduce pollution, reduce damage to the eggs, and improve the pass rate, fertilization rate and hatching rate of the eggs. [0003] In the field of artificial insemination of ducks, there are curre...
