During the winter, the following key measures should be taken in the feeding and management of laying ducks.
It is very important to control the temperature and temperature of wintering ducks at room temperature. Keeping the temperature in the shed at night above 5°C can ensure a high rate of egg production. Therefore, after feeding the ducks every night, the duck shed must be enclosed. Around the shed, straw or wheat straw can be used to wrap the grass around the shed, plus a layer of plastic film. The thickness of the cover grass, especially on the roof, must not be less than 5 cm.
In the laying area around the inner wall of the duck house, bedding of 30 cm thick clean soft straw or straw, etc., can be used to spread the old grass in the duck's house in the morning; Before the house was placed, new grasses were added for the production of egg nests to gradually accumulate the grass mats. Number of sunrise grass 1 times.
During the wintering period, the nutrient ducks need to keep warm and produce eggs. They consume a lot of energy and must increase the proportion of corn and other energy feeds. The amount of feed is 10% to 15% higher than that in summer and autumn, and adequate green feed or timing is provided. Vitamin A, vitamin D, vitamin E Adding 3% to 5% of fats and oils to the feed, and feeding chopped Chinese cabbage or radish cherry and other green feeds at noon every day, the effect will be better.
Adding to night foods, winter nights are long, and nighttime temperatures are low. If you can feed a warm feed at night, it will not only increase the nutrition of ducks and ducks, but also help the ducks to keep warm and increase the egg production rate by more than 10%. However, at night feeding should pay attention to two points: First, must provide warm drinking water, and second, night food should be based on high energy feed such as corn, protein can not be too much.
Hot-drinking drinks must be served in the winter with hot, warm drinks. The fine ingredients must be prepared with hot and cold water. The drinking water must also be warm and hot water. The temperature should be about 38°C. Do not drink ice-cold water.
Supplementing the light In winter, the natural light is less, and the decrease of the secretion activity of the glands in the duck's pit may cause the egg production rate to drop drastically, which requires manual supplemental lighting. The general requirement is that the daily lighting time can not be less than 16 hours. The light can be filled in the duck awning in an amount of 1 to 60 watts per 30 square meters. The bulb is 2 meters high from the back of the duck and fitted with a lampshade. Turn on the lights at regular intervals. It can increase egg production by about 20%.
More water is usually played when the temperature is high at noon. If the temperature difference between indoor and outdoor is too large, you should gradually open all the windows before you go to duck to adjust the temperature difference between indoor and outdoor. Then, the ducks were circling around the house for 4 laps to 5 laps. When 80% of the ducks screamed strongly, they were allowed to swim in the pool.
The density of high-density wintering ducks is preferably 8 to 9 per square meter, which is conducive to the self-insulation of ducks.
Special attention should be paid to epidemic prevention diseases in the wintering ducks house clean and sanitation, and often remove rubbish, excrement and other garbage. After the ducks are released during the day, all doors and windows must be opened for ventilation to keep the house dry and tidy. Once the diseased duck is found, it is necessary to isolate the diagnosis and treatment in time, and emergency disinfection of the duck house should be performed.
