(1) Artificial insemination
Artificial insemination can greatly increase the number of goslings that single goose males can breed, thereby expanding the influence of excellent male gooses and giving full play to their reproductive performance potential. At the same time, it can prevent the phenomenon of missing female geese in natural mating and improve the fertilization rate of the breeding eggs.
(2) Choose a good goose
Before the goose lays eggs. The body should be selected pure hair, thick chest, neck, thick feet long, two eyes with God, loud, flexible, male characteristics of the male goose; holding the goose's neck lifted off the ground when the goose feet Swim like a fierce swim, while both flapping frequently. In particular, check the goose's penis and eliminate goslings with poor penis development. Goose semen quality testing should also be conducted to eliminate male goose with poor semen quality.
(3) Choose the mother goose
The goslings should be rigorously selected and grouped one month before laying. Goslings choose the standard: handsome appearance, deep forequarters, hips wide and full, moderate fat and thin, relatively slender neck, eyes are God, moderate distance between the feet, the body was capillary and real. The abdomen is full and the touch is soft and elastic. The anus feather forms a bell. In particular, check if the pubic end is soft and elastic. The pubic bone spacing should be above the width of the two fingers.
(4) The proportion of scientific male and female goose
According to the requirements of the breeds of geese that are raised, the male and female geese should be properly matched. Generally, the ratio of male to female of small breeds is 1:6 to 7, medium breed is 1:4 to 5, and large breed is 1:3 to 4. Too many goslings not only waste feed, but also fight and compete with one another, affecting the fertility rate. Too few goslings and poor mating of laying geese can also affect fertility rates.
(5) Timely update of geese
The lifespan of the male goose is generally 2 years and does not exceed 3 years; female goose generally uses 3 years and does not exceed 4 years. At the end of the annual egg production, the geese must be strictly eliminated and new male and female geese should be added. Large-scale breeding goose breeding geese, advocated the use of all-in all-out system, do not advocate the breeding of different ages of the geese in the same group. In this case, the geese are generally available for 3 years and then eliminated at one time.
(6) Strengthening breeding geese
It should not be extensively reared from the shell to the age of 100 days, especially within 3 weeks after birth. After 100 days of age, the breeding geese enter the maintenance period, and they should use green roughage as the main ingredient and should not be fed too much fat. Four weeks before egg production, the geese diet was switched to use, the crude protein level was 15% to 16%, and 150 to 250 g of fine material was fed to each geese in the entire laying season. The goose during the egg production period should be formulated feed to ensure the energy and protein, vitamins, minerals, etc. required for egg production. Feed 2 to 4 times a day while supplying enough green fodder and drinking water. Places where conditions permit can also be grazing, especially in the second year of breeding geese should be more grazing, to supplement the green feed, sprinkle some shells and gravel on the sports ground, so that they can freely feed to meet the nutritional needs of breeding geese. The male goose should be supplemented with concentrates as early as possible. The diet should contain enough protein to allow it to have sufficient energy to breed and increase the fertility rate.
