In winter, the climate is cold and the sunshine hours are short. In general, the egg laying rate of laying ducks will be reduced. In order to make the laying ducks produce high and stable yields in winter, it is recommended to adopt the following comprehensive technical measures: 1. Select fine varieties. Optional Shaoxing duck, Kaki duck, Kangbei duck and other species, choose to stay 1-2 age mother duck. 2, strengthen the cold insulation. The most suitable ambient temperature for laying ducks is 13-20°C. Before wintering, measures should be taken to prevent cold and keep warm. The duck house and the vegetable greenhouse can be built together with 4-6 ventilation holes. The carbon dioxide and ammonia produced in the duck house can be used to grow vegetables through the stomata. The oxygen released from the vegetable shed and higher room temperature can be used. Improve air quality for duck houses. 3. Adjust the diet in time. Feeding batch materials, preferably full-price feeds, should increase the concentration of metabolic energy in the ingredients, and appropriately increase the corn or wheat feed (70-75% of the total amount of feed) so that 2987 kilocalories of heat energy and 17 calories per kilogram of feed are included. - 18% of the protein, but also add vitamin A 500 million international units, vitamin D 3.5 million international units, vitamin E 50 mg, in the feed can be added in an amount of betaine additives and 0.1% -0.2% of chili powder. 4. Forced moulting. In late autumn, the duck wings and large tail hairs were manually removed, and the concentrate feed was fed. After 20 days, the ducks laid eggs. 5, add light. A 60-watt reflector lamp is installed every 10 square meters. The bulb is 1.2-1.5 meters away from the ground. The daily light time is 14 hours. The time and intensity of the fill light should remain basically unchanged. Weakness stops and opens. 6, night feeding. At night, feeds containing low protein (adding about 30% of wheat granules) can be provided and sufficient warm water can be supplied. 7, do a good job "noise duck." In order to help ducks lose weight and resist cold, you can gently sip the ducks in the shed to make a circle, 7-8 times a day, every 4-5 laps. 8, playing the right water. On sunny days, each play lasts 1 to 1 hour, 0.5-1 hour each time. Before going into the water, ducks should be noised so that 80% of the ducks will make strong shouts to avoid freezing their water. 9. Grab young chicks and feed them in groups. Ducks generally start production at 24 weeks of age. Based on this calculation, spring brooding is appropriate. New and old ducks should be reared in groups. When ducks are over 500 days old, they should be eliminated in time. 10. The male and female ducks are polycultured in proportion. In addition to ducklings that require 5% of their ducks, 2-3% of ducks must be kept in ducks. Because ducks have sexual attraction and sexual stimulation in ducks, they can promote egg production in ducks. . 11, to avoid stress. Ducks are subjected to intense stress, but egg production rates are affected, and weight can cause illness. In order to avoid stress, it is necessary to: (1) maintain a relatively stable nutritional level of feed, fresh and sanitary; (2) supply high quality warm water; (3) keep quiet inside and outside; (4) provide ventilation and ventilation regularly; (5) put ducks, feed, rest There should be a fixed time for ducks, ducks, and fill light to make ducks live a regular life; (6) Decline the outsider from entering the duck home. In addition, we must do daily routine disease prevention work.
