From the current point of view of geese production, breeding geese generally suffer from the problem of low geese fertility, that is, the number of geese provided by unit geese is far below the theoretical value. Therefore, improving the breeding ability of breeding geese is an important prerequisite for raising the economic benefits of geese. According to the practice in the work and some advanced experiences of geese in various places in recent years, the author summarizes the following eight technical measures to improve the breeding ability of geese.

First, there are many varieties of fine goose breeds and goose breeders, and there is a great difference in reproductive performance among breeds of goose. Therefore, the selection of fine breeds of goose is a key step for a high-yield and high-efficiency production of goose farms. In addition to considering the market demand, the breeding geese must also consider reproductive performance and adaptability. When the species is determined, it is also necessary to do a good job in selecting and hunting the geese. Should choose to retain physical health, normal development, reproductive traits outstanding individuals who meet the characteristics of this species. For male geese who have stayed in the species, they must be examined one by one. The male geese with strong physique, good semen quality, and no stray hair should be selected.

Second, to strengthen the cultivation of reserve geese Reserve geese is an important part of improving the quality of breeding geese. The reserve geese before 4 months old should give full-priced feed. If there are grazing conditions, the intensive grazing should also be supplemented with concentrates afterwards. Under the conditions of grazing, it is necessary to feed the full amount of feed at regular intervals, and it is usually fed 3-5 times a day. Reserve geese from the age of 4 months to the time of laying and laying eggs should be restricted in feeding, increase the amount of coarse material, and concentrate should be reduced. In particular, it is necessary to strengthen grazing, exercise, and eat enough green material. This can not only improve its resistance to rough feeding, enhance physical fitness, but also control the mothers go on premature egg production, so as not to affect the future production of eggs and breeding geese qualified rate. Separate the male and female geese to prevent early mating of the goslings, resulting in poor male geese and reduced ability to rear the male geese. In the 15-20 days before the start of breeding, the amount of refined material is gradually increased.

Third, to optimize the structure of the geese The rational structure of the geese group is not only the need for organizational production, but also the need to improve fertility. In the production, the old male and female geese should be eliminated promptly and new geese should be added in a timely manner. The lifespan of common gooses does not exceed 3 years, and the lifespan of goslings does not exceed 4 years.

Fourth, breeding season to take scientific feeding feeding goose breeding has obvious seasonality. In the southern part of the country from October to May of the following year, the pasture gradually withered and the grass was seriously deficient. At the same time, the egg-laying geese demanded a large amount of nutrients and had high quality. In order to obtain a large quantity of high quality eggs, scientific feeding must be performed. . The method is: feeding 4 times a day, respectively, at 7:00 am and 11:00 am and 3:00 pm and 7:00 pm, each supplement 200 grams of concentrate, plus feeding grass, leaves 0.5- 1.0 kg, about 0.25 kilograms of distiller's grains, red glutinous rice or carrots, and feed the concentrate and coarse materials.

Fifth, adequate breeding of a reasonable sex ratio and breeding group will increase the fertilization rate of eggs. Generally, the proportion of male and female of large-scale geese is 1:3-4, medium-sized 1:4-6, and small-scale 1:6-8. Goose is a waterfowl and likes to play and breed in water. The goose farm with sufficient water source should change water every day. Keep water clean and improve the fertilization rate of eggs. Some species of male and female geese have very different physiques, natural mating difficulties, and low fertilization rates. In this case, artificially assisted breeding methods can be used. Artificial insemination is one of the most effective and best methods to increase the fertilization rate of breeding geese.

Sixth, rational lighting to take scientific and reasonable light is an important measure to increase the breeding rate of breeder geese. The general illumination time is 13-14 hours, and the light intensity of 25 lux can meet the needs of geese for egg production and breeding. Prolonging the lighting time in a timely manner can extend the egg production period of geese, increase the egg production, and increase the amount of eggs planted throughout the year, which is conducive to the improvement of the utilization rate of breeding eggs.

VII. Feeding of full-price compounded feed for production of geese and geese should fully consider the nutritional needs of the mother's egg production. The metabolic energy per kilogram of formulated diet contains 10.3-10.7 MJ, and the crude protein is 16%-17%. Calcium to phosphorus ratio of 2.5-3: 1. With the diet should be high quality green and juicy feed and concentrate feed, while vitamins, minerals. Free drinking water, free water. In order to increase the egg production and the fertilization rate of breeding geese, gooses should be fed with full-priced compound feed. According to the experiment, formula (%): corn 63.5, soybean meal 15.1, sesame seed cake 7.0, wheat bran 5, rapeseed cake 1.3, stone powder 4.6, salt 0.3, chicken premix 1.5, dihydrogen phosphate 1.7, feed consisting of feed Geese, the average egg production, fertilized eggs, and fertilization rates of the eggs are higher than those fed a single concentrate.

VIII. To ensure the health of the goose population for disease prevention and control is directly related to the egg production of the geese and the quality of the eggs.

Diseased geese have metabolic disorders, and their egg production, breeding ability, and the hatching rate of hatching eggs all decrease significantly. Therefore, we must conduct vaccination or drug prevention and control of common diseases in this area, especially pay attention to the daily cleaning of geese, to clean the pens every day 1-2 times, every other month and a half to kill The geese harmless disinfectant performs a complete disinfection of the geese and sports grounds. Feeding must not be fed with moldy feed, and some broad-spectrum antibiotics should also be placed regularly in the feed. In addition, non-workers should be prohibited from entering or leaving the breeding geese. Strict disinfection of the geese before entering the geese is also required to prevent the occurrence of epidemics.
