Problems solved by technology

The current method is mainly to increase the fertilization rate by increasing the dietary crude protein level of male Muscovy duck, or making a suitable semen dilution formula or timely insemination, but these single methods can only increase the fertilization rate to 65%-75%. %, still can not meet the requirements of mule duck production on the fertilization rate

Embodiment 1

[0025] (1) From the age of 170 days in spring, male Muscovy ducks are given artificial light supplementation for 30 consecutive days, 12 hours a day, and sperm collection begins at the age of 200 days;

[0026] (2) Add vitamin E30IU per kilogram of feed one week before male Muscovy duck semen collection, the crude protein is increased to 19.9%, vitamin A and vitamin C are supplied according to the conventional amount, and the metabolic energy is maintained at 19.9MJ / kg;

[0027] (3) The semen collection time is arranged at 9:00 in the morning. After the semen collected from 3 feathers is mixed with 5% glucose and semen 1:1, add 3000IU penicillin (0.1-0.3mg / ml) to 1ml of the mixture After mixing, dilute and mix, mix the semen and finish transfusion within 20 minutes;

[0028] (4) Insemination by turning the anus, squeezing the cloaca to discharge the feces, and then inserting the insemination device into the vagina of the female duck 2.5cm for insemination, the amount of insemi...

Embodiment 2

[0031] (1) From the age of 180 days, male Muscovy ducks in autumn and winter are given artificial light for 30 consecutive days, 12 hours a day, and sperm collection begins at 210 days of age;

[0032] (2) Add vitamin E35IU per kilogram of feed one week before male Muscovy duck semen collection, the crude protein is increased to 19.5%, vitamin A and vitamin C are supplied according to the conventional amount, and the metabolic energy is maintained at 19.9MJ / kg;

[0033] (3) The semen collection time is arranged at 10:00 in the morning. After the semen collected from 3 feathers is mixed with normal saline and semen 1:1, add 3000IU streptomycin (0.3-0.5mg / ml) to 1ml of the mixture Add and mix well, after diluting and mixing, the semen will be transfused within 20 minutes;

[0034] (4) Use anal insemination, squeeze the cloaca to discharge the feces, and then insert the insemination device into the female duck's vagina 3cm for insemination. The insemination volume is 0.1ml, and t...

Embodiment 3

[0037] (1) In summer, male Muscovy ducks begin to collect semen from the age of 200 days;

[0038] (2) Add vitamin E40IU per kilogram of feed one week before male Muscovy duck semen collection, the crude protein is increased to 19.5%, vitamin A and vitamin C are supplied according to the conventional amount, and the metabolic energy is maintained at 19.9MJ / kg;

[0039] (3) The semen collection time is arranged at 4:00 p.m. to avoid high temperature. The semen after harvesting 4 feathers is mixed with 5% glucose and normal saline at a ratio of 1:1, mixed with the semen at a ratio of 1:1, and then Add 3000IU gentamicin (0.05-0.1mg / ml) to 1ml of the mixed solution and mix well. After dilution and mixing, the semen will be transfused within 20 minutes;

[0040] (4) Insemination by turning the anus, squeezing the cloaca to discharge the feces, and then inserting the insemination device into the vagina of the duck 3.5cm for insemination, the amount of insemination is 0.15ml, and the...

Abstract

The invention relates to the field of poultry breeding, and concretely relates to an artificial insemination method for improving the fertilization rate of mule-duck hatching eggs. Through adopting nutritional regulation techniques such as a technique of carrying out artificial supplemental lighting on male Muscovy ducks, and a technique of adding vitamin E and crude protein levels into feeds, and the like, and complementarily taking synthesis techniques such as semen mixing and deposition, environment temperature and semen deposition frequency control in the process of semen deposition, and the like, the fertilization rate of hatching eggs in mule-duck production is improved. The method disclosed by the invention solves the problem that the existing methods such as methods of raising the crude protein level of daily rations of male Muscovy ducks, or methods of manufacturing proper semen diluent formulas or methods of carrying out timely semen deposition are low in fertilization rate of mule-duck hatching eggs, greatly improves the fertilization rate of mule-duck hatching eggs, and lays an important foundation for the expanded production of mule-ducks.

Description

technical field [0001] The invention relates to the field of poultry breeding, in particular to a method for improving the fertilization rate of breeding eggs in mule and duck production through environmental control, nutritional regulation and comprehensive insemination techniques. Background technique [0002] The screw duck is a hybrid offspring of Muscovy duck (Cairina moschata) and Anas Platyrhynchos (Anas Platyrhynchos). It has a good market prospect due to its low carcass fat. In France, 95% of the fatty liver production comes from stuffed mule ducks, and domestic mule duck production has become an important method of meat duck production. Because the parents of mule ducks are intergeneric hybrids, their offspring have obvious heterosis, but generally do not have reproductive ability. In the production of mule ducks, the fertilization rate of eggs through natural mating is only 30-45%, which has constituted the bottleneck of mule duck production, and artificial inse...
