High-yield feeding techniques of Egg Duck

First, the technical introduction. The high-yield feeding technology of laying duck is composed of a comprehensive production system with high technical level. It includes incubation technology, purine egg technology, feeding and management technology in each stage, and improved on the basis of the original technology according to the production practice, in order to achieve stable and high yield and achieve production benefits. Second, technical operation rules 1, site selection (1) should be close to ponds, reservoirs, slow flow of streams and rivers, away from villages or towns, to prevent pollution sources. The terrain is dry, the soil is free from epidemic pollution, and the soil has good air permeability and water permeability, preferably sandy soil. The site is sheltered from the wind and the sun, keeping a gentle slope of about 5 degrees with the water surface. (2) the saleable area of the duck house is calculated at 8 ducks per square metre, and it is appropriate to keep 1000 ducks in each building. The enclosure is hung to the eaves with straw curtains and a transparent plastic film is used to block the wind. There are 3 60W lights and 2 15W lights per 100 square meters. There should be a dry playground in front of the house that is slightly twice the size of the duck shed. The surface sports area is three times larger than the duck house and is surrounded by bamboo fences or nets. There should be shade facilities or plants around the duck house. 2. Select varieties (1) varieties: the high-yield egg duck varieties suitable for the natural environment and climate characteristics of our city are Shaoxing Ma duck and Jinding duck. The first laying period of Shaoxing duck is 130Mel 150 days, the annual egg production is 250Mel 300, and the egg weight is 59Mel 71g, which is suitable for grazing and captive rearing. Jinding duck begins laying at the age of 4 months, with high and stable egg laying performance, with an annual egg production of 260Mor 300 and egg weight of more than 70g. It is accustomed to living in salt water and sewage and has strong adaptability. (2) requirements for introduction and introduction of seedlings: introduction and introduction of seedlings to duck breeding farms or individual incubators with production and operation licenses shall not be introduced from epidemic areas. 3. The selection of appropriate breeding period for the feeding and management of ducklings has an effect on improving the survival rate and egg laying performance of ducklings. Generally speaking, it is best to raise "early spring duck" at the end of April and the beginning of May. You can also raise "late spring duck" in June or "autumn duck" in August. (1) start eating at the right time: the day after the duckling comes out of its shell, 1/3 of the ducklings are in a foraging state and can be fed at this time. Use more early rice to make a stuffy hard rice, with 10% glucose water. Add 10% leek to mix the rice. (2) pay attention to water release: boiling water before eating is the characteristic of raising ducks. Put water in a duck basket before feeding, 13Mel 15 ℃ on a sunny day, you can directly put water in cold water for about 5 minutes; in case of rainy days or cold weather, put water in the indoor wooden basin. For 1-2 weeks, water should be released every day about 15 minutes after feeding. (3) timely replenishment of animal feed: after the ducklings are reared for the third day, the ducklings should be fed with animal feed of 10% per cent, such as snails, shrimp, earthworms, small fish, etc., or with 5% fish meal mixture to promote the growth and development of ducklings. (4) replenishing green feed: from the third day, add 10% chopped green fodder to the feed, or put it into the water to eat freely, such as green vegetable leaves, aquatic plants, duckweed and so on. 4. Feeding and management of laying ducks in four seasons the laying performance of laying ducks is restricted by temperature, humidity, light and many other factors. Corresponding technical measures should be taken according to the changes of seasons. (1) Technical points of feeding and management in spring ① sufficient feeding. The temperature changes from cold to warm, and the sunshine increases, which is beneficial to egg laying, and an environment for stable and high yield should be created. Feed should meet the needs of laying ducks in terms of quantity and quality, with 16% crude protein in rations and 2800 kcal per kilogram of metabolic energy. ② pre-spring management. In the early spring, the temperature is relatively low, so we should keep the house dry and ventilated, do a good job in cleaning and hygiene, and change the bedding material regularly. Lack of natural light, artificial supplement of light for 5 hours a day to stimulate the gonadal development of ducks. ③ guarantees the supply of green feed. Green fodder can be sprinkled on the surface of the water during the day and fed in the middle of the house in the evening. Green feed and concentrate each account for 50%. When there is a lack of green feed, eggs can be added with multi-dimensional replacement, the effect is very good. ④ management at the end of spring. At this time, there is a mildew season, a little careless, prone to egg loss. The duck house is well ventilated, change the mat grass frequently, keep the house dry, prevent feed mildew, and disinfect the duck house, material trough and drinking fountain regularly. The weather is fine, let the duck move more outside the house and get in touch with the sun. (2) the key points of feeding and management techniques in summer ① to prevent heat and cool down. All the grass curtains around the duck house are removed to enhance air flow, and ventilation equipment can be installed under conditions to reduce the temperature in the house. Insist on releasing ducks early and closing ducks late. Don't drive ducks into the house in the evening. Enjoy the cool at night and rush into the house at 12:00. Make sure the ducks drink enough water, preferably from wells. ② feeds more green fodder such as water and grass to increase the protein content in concentrate. Feed should be kept fresh to prevent deterioration. Yeah, lay a lot of eggs in spring. For ducks with the same feathers, add 1-2% of fried and ground sesame or rapeseed and other oil crops to the feed to increase the egg laying rate in summer. ③ properly scattered ducks with vegetables to reduce feeding density. Duck houses and sports grounds should be swept frequently, water basins and tools should be washed once at a time to keep them clean and hygienic. ④ should pay attention to the weather change and drive the duck house in time before the thunderstorm. (3) Technical points of feeding and management in autumn in September, it is a key to raising laying ducks. There is not only a danger of maintaining more than 80% of the laying rate, but also a danger of sharp decline. ① replenishes artificial light and keeps light up to 16 hours a day. ② overcomes the impact of climate change, especially before the arrival of cold air, so that the range of microclimate change in the house is as small as possible. ③ should properly increase nutrition and supplement animal protein feed. ④ conducts a selection of ducks to separate ducks that have stopped laying eggs, or to eliminate them in advance, or to force molting. (4) Technical points of feeding and management in winter ① increased the level of metabolic energy in feed, up to 2900Mel 3000 kcal per kg, and crude protein was 20Mel 22%. Green fodder or eggs are supplied normally with multi-dimensional supply. ② protects against cold and heat preservation. The duck house will be surrounded by cold grass curtains to prevent the wind of thieves. During the winter, the bedding material is only added and kept dry, which is helpful to increase the temperature. ③ releases ducks late in the morning, closes them early in the evening, usually goes into the water less, and the temperature is high in the morning and afternoon, each time for 10 minutes. Before releasing the duck, practice the duck in the house for 10 minutes. ④ was given artificial supplementary light, and the light time was maintained for 16 hours a day. It is appropriate for ③ to increase the feeding density per unit area, 8-9 feathers per square meter. The ducks had better be fed with warm water. Third, matters needing attention 1. Often observe the feeding and egg laying of ducks. 2. To do a good job in duck epidemic prevention, duck plague, bird flu, bird flu vaccine and parasites should be injected and eliminated before captivity. 3. Pay attention to the cleaning and disinfection of the environment and utensils of the duck house, and keep it clean and hygienic.
