At present, many peasant households have made their own ducks “leisure†in winter and have reduced their income. How can we make hens productive in the winter and maintain an egg production rate of over 80%? Here are some of the technical measures adopted by large duck-raising ducks such as Huaguang Township, Xichong County, and are only for reference: 1. Pay attention to the supplemental light ducks. After entering the sheds at night, install electric lights for every 10 square meters.ç› 40 to 60 watt bulbs, about 1.2 to 1.5 meters above the ground (if grazing in the wild, no power supply conditions, it can also be installed in 1 m2 per square meter, 0.8 to 1.2 meters in height). overnight. Ducks under the effect of adequate light, increase the secretion of ovulation inducer, can promote the development of follicles and ovulation, increase egg production rate (fill light ratio can not fill light can increase 20 ~ 25%). Second, attention to induce "onset" In general, ducks should always stay in the feet of 2 to 5% of the male ducks, ducks have sexual attraction and sexual stimulation on the ducks, can promote the sexual function of ducks, improve Egg production. Third, pay attention to regular insect repellent after the winter to the duck to drive a locust, each duck with half a piece of crushed drive mix broken feed in the feed. This way, the duck body is free from defects, reducing the time of feathering, increasing the chances of feeding, and enabling the ducks to rest quietly. After the excretion of parasites in the ducks, it can reduce the nutrient consumption in the body, enhance the physique of the ducks, and facilitate the production of eggs. Fourth, pay attention to put aside the saying goes, goose should be green, ducks should be embarrassing. In order to make more eggs for ducks, grazing should be strengthened so that they can feed animal feed such as small fish, shrimp, river otters, snails, and cormorants in fields and ditches. When grazing time is low, 17% protein feed and appropriate trace elements should be fed to ducks. Fifth, night feeding supplement night feeding should pay attention to, first, enough to drink water, and second, the protein feed at night can not be too much. Night feeding can improve the egg production rate by about 10% compared to no-night feeding. Sixth, the deployment of feed winter ducks should appropriately increase the proportion of corn and other energy feed, but also provide green feed or regular vitamin A, D, E. Three to five percent of fat can be added to the feed, and chopped cabbage leaves and carrots are supplied once a day at noon. The effect is very good. When the room temperature in winter is 5 to 10°C, the amount of feed should be increased by 10 to 15% compared with spring and autumn. VII. Reducing the stress Metabolism of ducks and ducks is particularly sensitive to polluted air and other environments. Therefore, attention should always be paid to ventilation and ventilation, and sanitation should be done well. In winter, ducks should be fed to clean hot and cold water, such as feed well water. To use it now: play 1 to 2 times a day. Before playing in the water, you must drive the duck to slowly move around the circle for 4 to 5 laps before you go into the water. The water time is about 2 hours. China Agricultural Network Editor
