How to make the duck duck "winter" change to "winter production"
At present, many farmers in rural areas have made their own ducks “leisure†in winter and reduced their income. After several years of experiments, the author has figured out the measures to make the ducklings "winter" become "winter". First, adjust the ducks in the late fall and early winter, and eliminate the old, weak, sick, ducks, low-yield and discontinued ducks in the duck group. Lean ducks with good production performance and robustness are left behind. Second, cold insulation ducks and eggs suitable temperature is 10 °C -20 °C. The cold winter weather is not conducive to egg-duck egg production. The following methods can be used to imitate cold insulation: First, block the hole in the duck house and the wall, replace the bad tile, to prevent the thieves from invading; second, repair the doors and windows, and prevent the cold weather at night. Cover straw or double-layer plastic cloth to keep warm; third is to add a heat preservation sandwich or ceiling ceiling under the roof to block cold air from entering into the house; fourth is to cross the bamboo raft and wood bar under the house roof 2 meters from the ground. , And covered with straw or plastic sheeting; Fifth, in the duck inland (frame) on the surface of a thick pad dry mat grass, to ensure that the duck abdomen from the cold; six is ​​to increase the breeding density per unit area, can raise 8 per square meter - 9 to warm the ducks and ducks each other; the seventh is to adopt a greenhouse to keep the temperature above 10°C in winter. Choose yang shed, leeward, near water sources to build a greenhouse. 8-9 eggs per square meter, 300 ducks per room, and a 4.5 metre long and 8 meter wide duck shed. 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 made of bamboo and other skeletons, covered with straw. The floor is covered with hay. Third, promptly repellent insects in the winter to the duck to drive a locust in time, each duck crushed after the drive to mix feed in the feed, so that the duck body without flaws, enhance the duck's physique is conducive to egg production. Fourth, the deployment of feed winter duck in addition to egg production, but also to resist the 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. If the green feed is insufficient, 0.2%-0.5% of synthetic multivitamin for poultry needs to be added. The amount of sand in the feed must be mixed to aid digestion. V. Reasonably feed the feed and crush it, mix it with warm water and mix it with a hand to loosen the mixture to loosen the mixture. The temperature of the mixed material is about 38°C. They are usually fed 4 times a day, each time at 5 am, 10 am, 3 pm and 7 pm. Around 12:00 at night, they will be fed once more. Try to let the ducks eat and eat well. Sixth, when the supply of warm water temperature is low, if the ducks drink ice water or very cold water, it is easy to cause stress and reduce the egg production. Therefore, it is necessary to provide ducks with clean and warm water. VII. Supplementing light The ducklings require 16 hours of light each day during the laying period. Short winter nights, lack of natural light, artificial lighting must be added, a 40-60 watt bulb can be installed in the duck house every 5-20 square meters, 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 lights twice a day, morning and evening, and turn off the lights at 21.00. In case of heavy snow, dense fog and other dark and light conditions, the 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. Eight, correct noise duck ducks in winter noise can enhance the duck's ability to keep out the cold and digestion, so that ducks produce more eggs. The practice is: every day ducks before the water noise the duck for 10 minutes, first open the window, balance the temperature inside and outside the house, and then gently drive away the ducks in the house for a slow circular motion, when about 80% of the ducks issued a strong chirp , And let the ducks go out or go into the water. Nine, a reasonable release of water late in the morning and late duck duck early night, reducing the number of launches, shorten the time to launch. The general launch of water 2 times a day, every 5-10 minutes. Cloudy, windless days, water in the morning, once in the afternoon can not go into the water; snow days after the snow stopped after the water. Ten, health and epidemic prevention should be promptly removed duck dung, diligently change the mat grass, keep homes and outside clean. 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 or sulfathiazole spices prevention, to ensure that ducks healthy and strong, normal egg production.
