1 Prepare for brooding. The brooding house should be ready in the first half of the breeding period. Clean it, make up for cracks, block the rat hole, clean the doors and windows, clean the walls with 20% lime milk, and conditionally clean the floor. Put on cement and disinfect with disinfectant. After washing the sink, feeding trough and utensils, move it into the house, close the door and window, raise the room temperature to above 20°C, and the relative temperature is above 75%, then mix 4ml of formaldehyde solution per cubic meter, 20g of potassium permanganate, and fumigate. Disinfect for 24 hours. At the same time, we must also prepare good feeds and necessary medicines. The brooding house should be pre-heated 1-2 days before hatching. Large brooding uses flue, hot water or steam pipe heating methods. Flat raises should be prepared with fresh litter; online support nailed before the scaffold, height 60-80cm, width 1.5 ~ 2m, shop network tablets (plastic mesh or wire mesh), after disinfection and spare.
2 Purchase healthy goslings
2.1 Bring young animals into the field without the disease. If young goslings come from unhealthy goose breeder eggs or hatch eggs from low hatching rates, the early mortality rate will increase significantly. Therefore, in order to understand the source of the hatching eggs and the health condition of the breeding geese, it is necessary to enter the hatchery with strict management.
2.2 Selection of healthy goslings. Fluff should be selected to be clean, large heads, bright and shiny eyes, flexible activities, cry and crisp, grasping in the hands of elastic and struggling, abdominal size is moderate, soft, umbilical healed well, no blood spots, edema and omphalitis. Weak chicks, due to poor absorption of yolk in the abdomen, mostly present with abdominal enlargement, abdominal stiffness, wet umbilical adhesion, listlessness, unstable standing, delayed response, and lack of love for activities.
3 Feeding management
3.1 When water is opened. Boiling water (also known as “tidal mouthâ€) is the first time drinking water, and the principle of opening water before eating is adopted. When the goslings are brought back from the hatchery, they are immediately placed in a pre-prepared brooding house that eliminates poison and warms up. When the young goose fluff is dry and can stand, it can be given the first drinking water, which is the first pass of breeding goslings. If the drinking water is too late, it often shows that the athlete's foot loses water and contracts, commonly known as “dry clawsâ€. The first drink from the shell should not exceed 16-24 hours. It is best to drink 3% to 5% of clear warm sugar water (or dextrose water) for the first 7 days. If some of the goslings do not drink water, the breeder can grasp the head of the gosling and press the mouth several times into the drinker to let it learn to drink. The water depth in the drinking fountain should be 3cm. Starting from the 8th day, you can drink more than 24 hours of clean well water or tap water. The number of drinking fountains should be sufficient. In order to prevent goslings from playing with water, the drinking fountain mats (or hangers) can be used, and it is advisable that the height be flush with the backs of the goslings.
3.2 Open food. Generally after drinking water, the food that is eaten is generally washed with clear water and steamed into eight cooked glutinous rice, or soaked with boiling water into eight mature millet. When you feed, you can sprinkle the broken rice on the kraft paper or mat first, or sprinkle some on the goslings to induce the goslings to feed. Slowly, the goslings will come to feed. 1-2 days after the gradual conversion to full-price compound feed, granules can be purchased bred material, can also be self-formulated, the formula (%): cornmeal 58, soybean 27, fine rice bran 6, wheat bran 5, calcium hydrogen phosphate 2. 3, methionine 0.12, stone powder 1. O, salt. 35, trace elements 0.2, multivitamin O. 03. Within 7 days of age, the general can feed 6 to 7 times during the day, each time about 3 hours; night should be fed 2-3 times. Each feeding time 25 to 30 minutes. As the age increases, the number of feedings can be reduced.
3.3 Kaiqing. That is, for the first time, the green feed can be added, and green feed can be added 2 to 3 days after hatching. In order to acclimate the gastrointestinal function of goslings and prevent diarrhea, diets should be gradually increased from little to large. Green fodder generally refers to leaves, tender grass, such as cabbage, chicory or non-polluting weeds, such as dandelion, cat ear, etc. The old roots were removed from the green fodder, washed and cut into filaments. The length of the shreds from l to 10 days old was 1 to 3 mm, and gradually lengthened. 11-21 days old green feed can be given to 80% to 90%. The chopped green feed can be placed in the feed tank or mixed with the concentrate.
3.4 Brooding temperature. Under normal circumstances, the first week of brooding temperature is 28 ~ 30 °C, after the weekly drop of 1-2 °C, until the temperature dropped to 20 °C, then rely on natural temperature. The temperature control should be flexible. In actual feeding, the behavior of the goslings should be used to determine whether the temperature of the brooding is appropriate. If the temperature is appropriate, the response of the goslings is evenly distributed, with peaceful breathing, and a quiet sleep. When the temperature is high, the mouth is open for breathing, the wings are open, the fluff is fluffy, frequently drinking water, and the feed intake is reduced; if the temperature is low, they are crowded and get together. The sound is fine, the fluff stands upright, and the body curls. Therefore, the brooding room should have special care, day and night duty, do ground observation.
3.5 The brooding house should maintain proper humidity. It is generally required that the relative humidity in the first week of age be 65% to 70%, and the second week of age should be reduced to 65%, and then it can be maintained at about 60%. If the humidity is too high, induce coccidiosis, aspergillosis, E. coli, etc.; if the humidity is too low, the house is dry, the water of the gosling body is lost, the hair is brittle, the toes are dry, the appetite is weak, and the goslings are vulnerable to cold attacks. , suffering from respiratory diseases. The solution is to spray a small amount of water on the walls and aisles around the house, or put a basin on the stove to evaporate water to achieve the purpose of adjusting the humidity.
3.6 Feeding density of goslings. Must be based on variety, season, housing structure, ventilation conditions and feeding methods. Usually l-5 day old 25/m2, 6-10 days old 20-25/m2, 11-15 days old 12-15/m2, 16 to 21 days old 8 to 10/n12. If the density is too high, not only does the air in the house not be good, it may affect the development of goslings, and the geese crowd together to catch food. The growth and development are uneven, and it is also prone to spasm; the density is too low, the utilization rate of homes is low, and the cost is high. Therefore, timely adjustment should be made when the stocking density is unreasonable.
3.7 Control the ventilation of the brooding house. Under high temperature and high density breeding conditions, goslings emit large amounts of harmful gases such as ammonia gas, carbon dioxide and hydrogen sulfide due to breathing, faeces and moist litter. Over a certain concentration will affect the growth of goslings and reduce feed Conversion rate, and goslings are susceptible to respiratory diseases and even death. Therefore, the brooding house should be ventilated and ventilated regularly, according to the weather, the age of the goslings and the temperature within the house to properly grasp. In order to prevent the reduction of the temperature, the temperature of the sherbet should be increased by 1-2°C before ventilation, and the original temperature should be lowered after the ventilation is completed.
