At present, there are many farms in rural areas that make their own ducks “leisure†in winter and reduce their income. After several years of trials, the author explored ten measures that meticulously changed the winter duck from winter to winter. 1 Adjust the duck groups in the late autumn and early winter, and eliminate old, weak, sick, disabled ducks, low-yielding ducks and discontinued ducks in the duck group. Lean ducks with good production performance and robustness are left behind. 2 The suitable temperature for cold insulation ducks is 10～20°C. The cold weather in winter is not conducive to egg production in ducks and ducks. The following methods can be used to prevent cold and heat: 1 Block the hole in the duck house and the wall, replace the bad tiles to prevent the thief from invading; 2 Repair the doors and windows, and cover the grass in the cold at night in the cold weather. The curtain or double plastic cloth insulation; 3 under the roof, add a heat insulation sandwich or ceiling ceiling, blocking the cold air into the house; 4 in the house under the roof 2 meters above the ground, bamboo, wood, and with straw or Plastic cloth covering; 5 thick mats on the floor (shelf) surface to ensure that the duck abdomen will not be cold; 6 increase the breeding density per unit area, can raise 8 to 9 per square meter, to facilitate the duck Heating between each other; 7 feeding in a greenhouse, in the winter can be more than 10 degrees Celsius. Choose yang shed, leeward, near water sources to build a greenhouse. 8 to 9 per square meter, each duck house raises 300, build a duck house 4.5 meters long and 8 meters wide. The duck house is 2 meters high on the northern wall, 2.2 meters high on the south, 3 meters high on the ridge, and has a long slope at the top. In the east (western) gable, a working gate is left next to the north wall. The top is framed with bamboo and covered with straw. The floor is covered with hay. 3 Timely repellent insects are fed to the ducks in a timely manner to drive the locusts once. Each duck is fed with a half-pack of worms and then fed in the feed. This allows the duck body to be free of insects, enhance the nature of the duck, and facilitate the production of eggs. . 4 In addition to laying eggs for winter feed, ducks must also be protected against cold. Therefore, it is necessary to increase the heat energy in the duck and duck feed. Reference feed formula (%): corn 40, bran 23, broken rice 10, rapeseed cake 5, soybean cake 10, fish meal 7, bone meal 3, oil 2 and trace amount of salt. Also add some green feed. Such as green feed, do not add 0.2% to 0.5% synthetic poultry multi-dimensional hormones. The amount of sand in the feed must be mixed to aid digestion. 5 Reasonably feed the feed and pulverize it and mix it with warm water. Take it into the group and loosen it to loosen it. The temperature of the mixed material is about 38°C. They are usually fed 4 times a day. They are fed once a day at 5 a.m., 10 a.m., 3 p.m. and 7 p.m. Give it another round at around 12 o'clock in the evening. Try to let the ducks eat and eat well. 6 When the temperature of warm water is low, if ducks drink ice water or very cold water, they can easily cause stress and reduce the egg production. Therefore, warm water for ducks should be provided. 7 Light supplements for light and ducks require 16 hours of light per day during the laying period. Short winter nights, lack of natural light, must be artificially supplemented with light, a 40-60 watt bulb can be installed in every 5 to 20 square meters in the duck house, the bulb is 2 meters high from the duck back, and the lampshade is installed. The light is concentrated on the body of the duck and the light is uniform. Turn on the light twice a day, morning and evening, and turn off the light at 21b. In case of heavy snowfall, heavy fog and other dark weather, lights should be turned on early in the evening and the lights should be turned off in the morning. If necessary, it can be lighted all day. 8 correctly noise duck noise ducks in winter can enhance the duck's ability to keep warm and digestion, so that ducks produce more eggs. The practice is: every day before ducks go to the water noise before the duck 10 minutes, first open the window, balance the temperature inside and outside the house, and then gently drive out the ducks in the house for a slow circular motion, when about 80% of the ducks issued a strong roar At that time, let the duck out of the house or go into the water. 9 Reasonable release of water late in the morning, duck, night early duck, reduce the number of launches, shorten the time to launch. The water is generally sprayed twice a day for 5 to 10 minutes each time. Cloudy, windless days, the water in the morning, once in the afternoon can not go into the water; snow days after the snow stop and then into the water. 10 Hygiene and epidemic prevention should be conducted in a timely manner to remove duck dung, change ground and bedding, and keep clean inside and outside. Disinfect the pens, food troughs and utensils once a week. Do a good job in epidemic prevention and timely injection of duck plague and duck cholera vaccine. Usually can be used sulfamethazine spices prevention, in order to ensure that ducks Healthy and strong, normal egg production.
