In winter, the climate is cold. Ducks consume more calories and must be served hot and warm. Concentrate must be prepared with hot and cold water, drinking water must also be fed to warm water, the temperature to maintain the best around 38 °C, should not drink ice water, this is the key.
Take care of the whole group
The flocks were grouped and old, weak, sick, disabled and low-yielding ducks were consistently eliminated to reduce death and feed consumption.
Keeping room temperature
Overwintering ducks are important for keeping warm and cold, so be sure to keep the temperature in the night shed above 5°C to ensure high egg production rates. This requires that after the ducks are fed every night, the duck sheds must be enclosed and enclosed. Around the shed, straw or wheat straw can be used to wrap the grass around the shed, and the surrounding area is covered with a layer of plastic film. In particular, the covering grass on the roof can not be less than 5 cm thick.
Thick grass
In the egg production area around the inside of the duck house, a clean, soft straw or wheat straw with a thickness of 30 centimeters is put in place. After the eggs are smashed in the morning, the old grass in the nest can be spread in the duck house. Before each night, the ducks are put in the house. New grass was added for the production of egg nests to gradually accumulate mat grass. A few sunrise grass, both warm and save manpower.
Nutrition
Duck winter must not only protect the cold but also produce eggs. It consumes a lot of energy and must increase the proportion of corn and other energy feeds. The amount of feed is increased by 10 to 15% compared to summer and autumn. It also provides sufficient blue-green material or regular vitamin A supplementation. Vitamin D, vitamin E. If 3 to 5% of fat can be added to the duck and duck feed, the green feed such as chopped cabbage or radish sprouts will be supplied once a day at noon, and the effect will be better.
Night food
The winter nights are long and the nighttime temperatures are low. If you can feed one time warm feed at night, it will not only increase the nutrition of ducks and ducks, but also help the ducks keep warm and increase the egg production rate by more than 10%. However, at night, supplementary feed should pay attention to two points: First, it must provide warm drinking water, and second, night-time food should be dominated by corn and other high-energy feeds. Protein should not be too much.
Tim playing water
Feeding ducks in winter for 1 or 2 times a day can increase the amount of activity and improve the resistance of ducks. Splashing is generally performed when the temperature is high at noon. If the temperature difference between indoor and outdoor is too large, you should open all the windows before you go to the duck to adjust the temperature difference between the inside and the outside, and then move the duck and slowly move around the circle for 4 to 5 turns, when about 80% of the ducks give off a strong buzzing sound. Allows ducks to swim in the pool. It should be noted that when the weather is harsh, the temperature is below -5°C and the ducklings do not have a strong tweet, do not swim.
Add light
It is generally required that the necessary light hours per day must not be less than 16 hours. The light can be filled in the duck awning at an amount of 1 to 60 watts per square meter. The bulb is 2 meters high from the back of the duck and fitted with a lampshade. Turn on the lights at regular intervals. Practice has proved that filling light ratio can not increase light production can increase 20%. It is better to feed 8-9 ducks per square meter for the density of overwintering ducks in order to facilitate self-insulation of ducks. At the same time, the wastes such as urine, grass and grass are often removed. After the ducks are released during the day, they must open all the doors and windows for ventilation and 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.
