Third, breeding technology
1. Hatching technology
1.1 choose high quality eggs. Choose hatching eggs with fast growth, good meat quality, disease-resistant Wanxi white goose and Rhine goose. It is a group of healthy geese who are not infected with infectious diseases in the base. The proportion of male and female spouses is appropriate, feeding and management are normal, nutrition is better fed, and the best quality of eggs is 3-4 weeks after opening. The hatching rate is high within 2 weeks after delivery, and the egg shape is required to be normal. Long working hours, roundness, waist drums, and sharp tips are not suitable for breeding eggs. Eggshells require a dense, uniform surface with moderate thickness. The surface of the eggshell is clean, and pollution is generally not suitable for the egg.
1.2 eggs preserved. Eggs should be stored at 13 to 16 degrees, relative humidity of 75% to 85%. It should be kept for more than 1 week and it should be turned once a day. The preserved eggs should be well ventilated and clean.
1.3 eggs disinfection. With benzalkonium chloride solution (5% solution), add water 50 times, prepare a 0.1% solution and spray on the surface of the egg with a sprayer.
1.4 Egg hatching conditions. The suitable temperature required for the first 10 days is 36.5-38.5 degrees, and the eggs can be attached to the eyelids, and the heat can be felt without being hot. In the middle 10 days, the requirement is lower, generally 36.5-37.5 degrees, and the latter 10 days are appropriate at 37-38 degrees. The humidity requirement is also high and low, requiring 65%-70% in the first 10 days, 60%-65% in the middle 10 days, and 65%-75% in the next 10 days. Wet and dry thermometers can be used for measurement. During the incubation process, ventilation should be performed at least once a day for more than 3-4 times, but when ventilating, cold air should be prevented from blowing directly onto the surface of the eggs. Every day and night, flip the eggs 8-12 times, the angle is not less than 45 degrees, after hatching the second week, pay attention to the big head of the egg.
1.5 The machine hatches.
1.5.1 Preparations before hatching. Before hatching, develop a hatching plan, overhaul the hatchery, and prepare hatchery spare parts and accessories.
1.5.2 eggs hatch. Before hatching, it is preheated at 22 to 25 degrees, and then the plate is placed. Eggs are laid flat so that the hatching rate and the rate of hatching are high. And number the egg trays and make arrangements.
1.5.3 The daily management of the hatchery. Pay attention to changes in temperature and humidity, and always pay attention to whether the operation of the machine is normal.
1.5.4 according to the egg. During the incubation period, the eggs should be irradiated 3 times in order to detect stone eggs and dead eggs in time and observe the development of the embryos.
1.5.5 landing. The goose eggs hatched until 27-28 days. The eggs in the hatching machine were moved into the hatching tray of the hatching machine. Afterwards, turning the eggs was stopped, the water dish was increased to increase the humidity, and the eggs were placed in the tray for the last time.
1.5.6 handling of hatching. A large number of shells are hatched in about 30 days. At this time, the internal lighting should be turned off. During hatching, empty goose husks and dried fluffy gooses should be picked up as appropriate to facilitate continued hatching. Before hatching, goslings that have difficulties in hatching may undergo artificial midwifery. The hatchery floor should be sprinkled with water regularly to maintain adequate indoor humidity.
2 Feeding Management of Goslings
2.1 young goose into the farm. Goslings are gooses that are 4 weeks old after hatching and are called goslings. My county generally enters goslings in early May. At this time, the climate changes from cold to warm, and brooding is more beneficial. Herbs are sprouted and can be used as green feed for goslings. When the gosling grows to 20 days old, the green feed has generally grown and the texture is crisp and can be grazing throughout the day. Farmers in my county can use mat grass flat raising, to warm the young, the most suitable temperature is 25-28 degrees.
2.2 Feeding.
2.2.1 Early water supply. When young goose fluff is dry and can stand, it can be given the first drinking water, commonly known as "tidal mouth." The method is to press a part of the gosling's mouth into the drinking water several times, so that the goslings can learn to drink water, and the water depth of the drinking fountain is 3 cm. Goslings should be clean drinking water, it is best to cool water, water temperature is 25 degrees is good, the water should be added 0.05% potassium permanganate solution, and even drink 7 days to prevent digestive tract diseases.
2.2.2 eat at the right time. The food is generally eaten within 24 to 36 hours after hatching. Opened feed commonly used broken rice and millet, soaked in water for about 2 hours before draining. Green fodder commonly used bitter leeks, vegetables, etc., cut into 1-2 mm filaments, open food methods can be first after the Qing Jing, can also be refined after the green.
2.2.3 Timely grazing. 10 to 20 days after hatching, the first grazing can be performed depending on the weather conditions. Choose a place close to the goose house, where the road is flat, the water quality is clean and free of pollution, and the grass is fresh. It is advisable to graze the geese with 300-500 eggs and require the same or similar age. When young goslings begin to grow up, they can grazing all day and only need to feed once a night.
2.3 gosling management.
2.3.1 Cover the goose shed. It is required to be built in a high-drying place, able to shelter from wind, rain, and heat. It can prevent rat and animal damage.
2.3.2 rearing groups. Pay attention to divide the goslings into groups of 50 in groups, so as to prevent colonization from causing casualties or heat and affecting growth.
2.3.3 Vaccination. For mother geese that have not been vaccinated with gosling geese, 0.1 ml of gosling fleas antiserum should be used for prevention within 24 hours of hatching.
3 Feeding Management of Goose
3.1 Feeding. Young geese from 4 to 10 weeks old are called gooses. It is the most economical and feasible to use feeding methods that combine grazing and house feeding. The goose must have a sufficient amount of green fodder to put pasture on the pasture. The longer the grazing, the better. Go back and get home late, eat 5-6 satiates each day, and supply vegetables and wild vegetables at night.
3.2 Management. The parasite is treated with praziquantel, 10 mg per kilogram body weight is administered orally.
4 Feeding Management of Fattening Geese
Feeding should be adequately fed and fast fattening; management should limit activities, ensure quietness, and control light to facilitate long-term breeding. It is mainly suitable for the seeds that have more grain real feed for grazing and eat more weeds. At night, feeds made mainly of corn, cereals, and bean cakes can be replenished.
5 for sale.
