1. Increase insulation and cold-proof measures
A plastic greenhouse can be built in connection with the duck shelter. This is an important and practical measure for keeping warm and protecting against cold. If the duck house has a thick insulating layer, good sealing performance, a large lighting area in the plastic greenhouse, and a timely combination of daily coverage and uncovering the grasshopper, even in the cold January, when the outdoor temperature reaches -10 °C at night, the duck house and The temperature inside the plastic greenhouse can still be maintained above 10°C. This creates a more suitable temperature environment for the high yield of ducks in winter. The construction method for plastic greenhouses is basically the same as the method for building greenhouses. The plastic greenhouse and the duck house should be closely connected, and the interior should be open, which is conducive to feeding ducks, drinking water and exercise. The area of ​​plastic greenhouses should be more than two-thirds of the area of ​​ducks. In the plastic shed, a sink is located on the south side, and the trough is set next to it. The rest is the sports ground. As plastic greenhouses and duck houses are only well sealed, they can have good insulation effect, which will cause certain difficulties for the ducks to provide fresh air. Therefore, you must open doors, windows, and vents at noon every few hours to drain all the dirty gas in your home. After catching the ducks before the evening, all doors and windows must be closed.
2. Scientifically formulated diet
High-yield ducks in winter must be prepared in accordance with high protein, high energy standards. The specific standards are: crude protein 18%, energy 11.76 ~ 12.18 MJ / kg, methionine 0.4%, lysine 0.9%, effective calcium 2.5%, available phosphorus 0.6%, duck and duck with a large number of multidimensional and trace elements. For a long time, there are only a few manufacturers that produce duck and duck feed. Most duck farmers use duck feed to feed ducks. This is an important factor that restricts the high and stable yield and economic efficiency of ducks. Therefore, when formulating duck and duck feed, it must be rationally formulated according to the above-mentioned nutritional standards. Feed ingredients need to be of high quality and variety in order to meet the needs of ducks for various nutrients.
3. Appropriately increase lighting time
The winter nights are long and short, and the natural lighting time alone can not meet the demand of high-production laying ducks. It is necessary to artificially increase the lighting time. It is better to artificially increase the illumination to 60 watt fluorescent lamps. The lamp is 2 meters from the ground and 5 watts per square meter (including the area inside the plastic greenhouse). The specific increase in lighting time is from the evening to 10 o'clock in the evening and from 6 o'clock in the morning to dawn. It is not advisable to increase the light of the duck population for a long period of time. It is advisable to increase the daylight by more than half an hour compared with the natural light. Gradually the transition to evening light at 10:00 pm, the time for increasing the light in the morning may not change. If you increase the light too quickly, it is easy to cause the duck to recoil. When a large group of ducks are extinguished when the light with increasing light is extinguished, some lights with a low light level must be left unobstructed to allow the ducks and ducks to walk and drink water in order to avoid causing frightening groups and causing stress and reduce egg production.
4. Pay attention to exercise
High-yielding ducks in winter only rely on a small amount of exercise in the plastic canopy of the duck house. It is not enough to build a playground outside the plastic duck can that is more than twice the size of the duck house. When the weather is warm, ducks can be kept outside. Sports field activities. Ducks are waterfowl animals, especially like water, ducks can only play its full function after entering the water. Ducks drill in the water and are particularly active. Ducks and ducks also love to be clean and have slight pollution on their bodies. They must wash them clean in the water. The duck hair is bright and fluffy after washing. The insulation is better. Ducks rarely get sick and their production performance is strong. Artificial pool is because of the extraction of groundwater, compared with the natural rivers and ponds have the following advantages: First, no pollution, good water quality; Second, cool in winter and summer, suitable for long-term high-yield ducks; Third, water and drainage are completely controlled by the artificial, water level stable.
