Feeding technique of breeder goose with temperature, light and ventilation feed

The objectives of feeding and management of breeding geese during the laying period are as follows: strong physique, high and stable yield, high fertilization rate and hatching rate of breeding eggs, completion of breeding and breeding tasks, good technical indicators and economic benefits.

Breeder goose

1. Nutritional requirements and formula feed. Breeder geese consume too much nutrients, especially energy, protein, calcium and phosphorus, because continuous laying and reproduction, so the level and balance of feed nutrition directly affect the production performance of female geese. The egg-laying feed was fed about 20 days before the breeding of geese. Because geese are mainly raised in our country, grazing is mainly in the south, and house feeding diet is only a supplement. Therefore, it is necessary to adjust the formula feed according to the local feed resources and the nutritional requirements of geese in each growth and production stage.

2. For house-fed geese, it is recommended that the dietary nutrition level is 10.88 kJ ~ 12.3 kJ / kg, crude protein 14% 16%, crude fiber 5% 16% (no more than 10%), lysine 0.8%, methionine 0.35%, cystine 0.27%, calcium 2.25%, available phosphorus 0.3%, salt 0.5%. According to the experiment, the geese were fed with the formula feed made of 40% corn, 12% bean cake, 25% rice bran, 5% rapeseed cake, 1% bone meal and 7% shell powder. The average egg production, fertilization rate of fertilized eggs and fertilized eggs were 3.1%, 3.5% and 2% higher than those fed with single rice, respectively.

3. In addition, the practice of raising geese at home and abroad has proved that feeding green succulent feed is beneficial to improve the reproductive performance of female geese. Therefore, if there are conditions, more green feed can be fed during the breeding period of geese.

4. Suitable ambient temperature. Goose physiological characteristics: down plump, more down feather content; subcutaneous fat, but no sebaceous glands, developed tail sebaceous glands, difficult to dissipate heat, so the goose is cold-resistant, heat-resistant and sensitive to high temperature. The temperature is high in summer, geese often stop production, and male geese have no sperm motility. In the management of egg-laying geese, we should pay attention to the temperature and do a good job of heat prevention and cooling in summer.

5. Suitable light time. The intensity of light and the length of time affect the fecundity of breeding geese. At suitable temperature, increasing light to geese can increase egg production. Natural light plus artificial light, not less than 15 hours a day, usually 16-17 hours, until the end of egg laying. At present, many kinds of geese are raised by open goose house and natural light system, and the lack of light time affects the egg laying of breeding geese. Therefore, in order to improve the laying rate, we should supplement the light, from one month before the beginning of production, from less to more, directly to the suitable light time. Increase the artificial light time in the morning and evening respectively. Different breeds of geese need different light in different seasons, so lighting plans should be made according to seasons, regions, breeds, natural light and the age of laying eggs, which shall be carried out according to the plan and shall not be adjusted at will.

6. Reasonable ventilation. During the laying period, the grazing of breeding geese decreased, the time spent in the goose house increased, food intake and excretion increased, which would pollute the air in the house, reduce oxygen, affect the health of geese and reduce egg production. In order to keep the air fresh in the goose house, in addition to controlling the feeding density (1.3 ~ 1.6 per square meter and 2 per square meter under grazing conditions), timely removal of feces and bedding grass, the doors and windows should always be opened for ventilation.
