The spring climate is variable, especially in early spring, with low temperature, large temperature difference between day and night and inside and outside, duck disease and slow growth. The adaptability and resistance of the external environment are not strong, so feeding and management must be strengthened. Generally should do the following: First, choose the site to raise the farm site should choose leeward, sunny, quiet, keep warm, cold place, while the water source is better (requires live water). Second, the preparation of brooding room Therefore, the brooding room should do a good insulation properties, air should be kept fresh, smooth, dry, to prevent the invasion of thieves. The floor should be paved with 3 to 5 cm thick bedding. The litter should be kept clean and dry and free of mildew. The brooding room can be heated in a variety of ways, such as "ground fire dragon", "heat preservation umbrella", "infrared light bulb" and "coal furnace plus flues". Before brooding, the brooding chamber can be fumigated with formalin plus potassium permanganate. The walls can be brushed with 20% lime milk; the ground can be disinfected with a 5% bleach suspension. Wood and bamboo feeding utensils can be sprayed or washed with 2% sodium hydroxide solution and then rinsed with water. Third, planting green feed In the early spring, there are fewer natural pastures, and some grasses, alfalfa, etc. need to be planted artificially to provide the necessary green feed for the cherry valley ducklings. Fourth, to improve the nutritional level of feed This season, the weather is changeable, duckling resistance is relatively weak, therefore, to improve the nutritional level of feed is very important. The protein content of the duckling feed should be increased by 3% to 5%, and the energy in the feed during the rearing period should be appropriately increased, and the feeding amount should also be increased appropriately to resist cold consumption. 5. Careful selection of cherry valley ducklings should be selected from healthy, disease-free cherry grain ducks. The cherry valley ducklings should be of moderate weight, standing steadily, and at the same time sound loud, action should be lively, eyes have a great deal of God, and responsive; yolk contraction is good, hands touch the abdomen should be soft, the anus should be clean; fluff looks to be fluffy and clean, After the hair shaft can stand firm and powerful. When you hold your neck and lift it up, your feet quickly shrink. For the abdomen, bread and other weak young to be eliminated. Hejian City Animal Husbandry and Fisheries Bureau Cheng Hongli Six, strengthen feeding management 1. Grouping and anti-piling. Grouping should master suitable breeding density and prevent ducks from “playingâ€. To do day and night inspections group by group, hand the ducklings to operate 4 to 5 times, to prevent the ducklings from being stacked and causing freezing above, intermediate heat, and under pressure. When brooding from the temperature, in particular to control the density of ducks, generally in the first week, 35 to 40 cm in diameter basket or folding circle to raise about 15, then gradually reduced to raise about 10 or so. When raising chicks, the number of ducklings per square metre is 25 for 1 to 5 days, 20 to 25 for 6 to 10 days, 15 to 12 for 11 to 15 days, and 10 to 8 for 15 days. Only, each group is 100 to 150. 2. Insulation moisture. Due to the cold weather, it is necessary to warm the ducklings. The l-5 day old age is 27°C to 30°C, the 6-10 day age is 25°C-26°C, the 11-20 days age is 20°C-24°C, and the 21st day later is l7°C-20°C. 3. Look at Duck Shi Wen. When the temperature is low, the ducklings approach the heat source, play piles, stand unsteady, tremble, shrink into groups, and scream from time to time. At this time, they need to be warmed. Conversely, if the young goslings are far away from heat, they breathe out their breath and the back feathers are damp. When the drinking water is frequent, the temperature should be lowered; when the temperature is appropriate, the ducklings are evenly distributed, quiet and silent, the feathers are smooth and bright, and the appetite is prosperous. When brooding, we must also pay attention to night and cloudy temperatures should be higher; at noon during the day, sunny days should be lower; small groups should be higher, large groups should be lower; weak chicks should be higher, strong chicks should be lower. In addition to the temperature, we must also have a good understanding of the humidity. In general, the relative humidity in the first 10 days is kept at 65% to 75%, and after 11 days, it is maintained at 60% to 65%. 4. Correctly deal with the relationship between insulation and ventilation. If emphasis is placed on the insulation of the duck house and the ventilation and ventilation are neglected, air pollution in the house can easily be caused and a large number of pathogens can be produced. Ducks inhale harmful gases such as carbon dioxide and ammonia for a long period of time and grow in environments where bacteria grow. They often develop high E. coli and chronic respiratory diseases. 5. Drink water early. The first time of drinking water is generally about 24 hours after the shell is hatched. When the ducklings are dry and can walk freely, there is a phenomenon of feeding the feet and padding. To clean the water, it is best to add a small amount of glucose or vitamins to the water. You can use pots of water to press the ducklings into the water basin, allow them to drink water, and teach them several times. The ducklings will drink water. To prevent the occurrence of digestive diseases, 0.05% potassium permanganate solution can be used as drinking water. Afterwards, the duck house should be provided with enough water to ensure that the ducklings can drink water at any time, but keep in mind that the brooding room should be kept dry and the humidity should not be too high. 6. Start eating at the right time. After the first time drinking water, the ducklings showed behaviors such as neck stretching and mouth opening. Feeding brooding materials should be wetted with water, and it is advisable to feed them by hand. The specific method is to spread the feed on plastic sheets for ducklings to feed freely. For ducklings that will not feed, put the ingredients on their mouths, induce their feeding, and after several adjustments, they will eat. After the food is eaten, there must be enough food in the duck house to ensure that the ducklings feed at any time. 7. Reduce stress. Ducks are very sensitive to changes in the external environment. Therefore, there must be a certain amount of time and order for ducks to feed, add water, sanitation, and excrement, and fix the breeder. Exercise should be gentle at work and strangers and other animals are strictly prohibited from entering the duck shed. If there are strong noises from the outside world, such as firecrackers, wind whistling, etc., the keeper must enter the duck house in time to create a safe atmosphere for the ducks to be “the owner is on the sideâ€. You can also add appropriate amount of vitamins or other anti-stress drugs to duck feed or drinking water. 8. Strengthen health management. The pens should be often cleaned, and the grass should be diligently replaced by the sun. The feed tanks should be brushed with alkali water once a week to prevent the propagation and spread of insects, mice, and flies. 9. Disease prevention and control. When ducklings are raised in the early spring, prevention and control of epidemics should be done well. The first is to do good health. Set up a disinfection tank at the entrance. The duck house should be changed over and litter regularly, clean the excrement inside and outside the site every day, and rinse the brooding utensils. The keeper must change shoes in and out, try not to use tools from other farms, and if necessary, strictly disinfect it. The outside of the duck house should also be regularly cleaned and disinfected. Do not stack garbage or duck droppings. Lime powder should be sprinkled at the door. The second is to establish a disinfection system. The duck house should be regularly sterilized with a small irritating disinfectant according to the prescribed dose. At the entrance of the duck farm, it is sprayed with 3% hot alkali water every 7 to 10 days. The duck house is generally spray-sterilized once a week. After each batch of ducks is sold or slaughtered, it must be completely disinfected. The third is to do a good job of vaccination and drug control. In the brooding and breeding stage, immunization of vaccines should be done in time to prevent the occurrence of diseases. The brooding stage focuses on the prevention of viral hepatitis and infectious serositis.
