Geese have a low rate of reproduction and generally produce only a few tens of eggs per year each year, and fewer eggs are produced under traditional seasoning conditions. In addition, all the geese start egg production every year from March to June, and hatching goslings from April to June. The newly raised goslings are all concentrated and sold in July and October. Due to the over-concentration of products, goslings are sold. The price is low and the selling price of the goose is also low, which reduces the economic benefits of geese. The best way to solve this problem is to use science and technology as the guide to raise the anti-season goose, that is, let the geese begin to lay eggs from September to October of that year. It will be produced until March to April in the coming year, and will be hatched in late November. The goslings supply a tight goose market with significant benefits.
The anti-season breeder geese began to lay eggs in October of that year. At this time, the sunshine duration of natural sunlight is gradually shortening, the sunshine intensity is gradually weakening, the temperature is gradually declining, and these environmental factors closely related to the production performance are changed. Very unfavorable. Therefore, it is imperative to strengthen feeding and management to provide a comfortable and safe environment for breeding geese, ensuring high egg production rates, fertility rates, hatching rates, and hatching rates.
The nutritional level of egg production geese diet should be: metabolic energy 11.3 ~ 11.7 MJ / kg, crude protein 16% ~ 17.5%, crude fiber 5% ~ 6%, calcium 2.2% ~ 2.6%, phosphorus 0.6% ~ 0.7 %, lysine 0.69%, methionine 0.32%, salt 0.2%. Feeding feeds 3 times a day, feeding 150-200 grams per day, and feeding once a day at 9 o'clock will be better. In addition, we must often supply 20% to 25% of green feed, set up pots in the house and sports grounds, and add clean shell particles for geese to eat freely to meet the needs of the geese for minerals.
The suitable temperature for breeding goose eggs is 5°C～25°C. When the temperature is lower than 0°C, the geese can reduce or even stop producing eggs. Therefore, the winter cold insulation can not be ignored. (1) The top of the goose shed is covered with straw or plastic film, and the back wall and gable are sealed. The front wall is only left for the import and export of geese, and other parts are covered with transparent plastic film. (2) Overlay 5-8 cm thick clean dry litter inside the shed and guard against mildew. (3) It is forbidden to carry water inside the house to keep the humidity in the house no more than 65%. Avoid high humidity and low temperature and cause great harm to the breeding geese. (4) Goose in the morning and in the late morning, goose in the early morning, do not put goose in the cold and rainy days, and prevent the goose from eating snow. (5) It is forbidden to breed frozen gooses and drink frozen water to prevent diarrhea.
The time and intensity of light are the key factors affecting the breeder's egg production. The appropriate lighting system is to ensure 15 hours of light every day and night, and the natural light is supplemented by two parts, morning and evening. Artificially supplemented lighting must be regular, otherwise it will seriously affect the production of geese. Appropriate light intensity is: every 40 square meters of light bulbs with an area of ​​18 square meters hang 2 meters high, and often wipe it clean, with better cover.
Maintain the appropriate ratio of male and female breeding geese. Small geese 1:6 to 1:5, medium-sized geese 1:5 to 1:4. Observe the mating situation of the male geese regularly and adjust the goose at any time to ensure that the fertilization rate of the breeding eggs reaches the desired level (85% or more).
Maintain the proper slope of the geese to bathe along the edge of the pool. The suitable gradient on the edge of the pool should be 15 to 20 so as to facilitate the bathing and mating of the geese and increase the fertility rate.
In addition, it was found that when breeding geese in nests (big nests), they should be caught in a room with low-temperature and no-wool nests in a timely manner so that they can quickly wake up and resume egg production. They must not be allowed to suspend long-term production.
