Embodiment Construction

[0030] Further illustrate below in conjunction with specific embodiment:

[0031] First, determine the breed of eugenic male goose:

[0032] a) Select medium-sized geese with an adult body weight of 5-6.5kg as the breed geese. Through observation, select 20 adult male geese with strong body, loud voice, bright feathers and normal reproductive organs from each breed of geese. Calibrate;

[0033] b) Artificial semen collection was carried out on selected male geese of each breed, once a day for 7 consecutive days, and sperm collection was performed on the calibrated adult male geese by massage method;

[0034] c) Compare the quality of sperm. After mixing with the diluent, refrigerate at 3°C ​​for 24 hours. After the refrigerating time, compare the sperm activity and quantity; select the semen with four or more times and the quantity is not low Breed geese with an activity of not less than 600 million per milliliter and no less than 60% are considered as eugenic male goose bre...

Abstract

The invention discloses a method for artificial insemination of goose sperm suitable for refrigeration. The method comprises: firstly, the breeds of eugenic goose were obtained by population comparison, then the sperm quantity and sperm motility were compared under specific conditions, and the goose whose sperm fertilization rate was still very high after refrigeration was selected as breeding goose; then induced feeding was carried out in the farm; adding herbs rich in selenium, zinc and iron to feed, supplemented with vitamin E; Make up the light ahead of time, prolong the light time, make the male goose enter the breeding period ahead of time; carrying on the physical strength exercise, prolongs the goose to gather the semen the frequency continuously. Through the method, the egg production quantity and the egg laying rate are increased, and the problem that the sperm collection and insemination operations cannot be carried out in time is solved in particular.

Description

technical field [0001] The invention relates to an artificial insemination method, in particular to breed selection and semen preservation in goose farms where insemination cannot be performed immediately after semen collection. [0002] technical background [0003] With the rapid development of the waterfowl industry, especially the industrialization and large-scale breeding of geese are getting more and more attention. As a waterfowl, geese have the habit of mating in water. Although the mating and fertilization rate in water is higher than that on land, it is very uncontrollable. There are three main methods of natural mating at present, which are large population mating, small interbreeding, and individual single mating; in order to obtain patrilineal families and carry out descendant determination, there is also the method of dioecious rotation mating. [0004] In order to obtain a better egg fertilization rate, artificial assisted breeding and artificial insemination ...
