What are the precautions for raising laying ducks in autumn?

????1. Adjust the daily ration and feed reasonably.

In autumn, an appropriate amount of animal protein feed should be added to ensure the quantity and balance of amino acids, especially essential amino acids such as methionine and lysine, double the addition of multiple vitamins, and pay attention to the calcium-to-phosphorus ratio and the addition of trace elements. Generally, the nutritional level of the autumn duck daily ration is 18% crude protein, 0.3% methionine, 0.7% lysine, 8% crude fiber, 3% calcium, and 0.6% phosphorus. The amount of concentrated feed fed to autumn ducks should depend on the laying rate of the flock. If the laying rate of the flock is above 50%, more concentrated feed can be added. Otherwise, some green feed can be given, or the amount of bran and middlings in the concentrated feed can be increased while reducing the amount of carbohydrate raw materials.

????2. Supplement lighting.

In autumn, the natural daylight hours gradually shorten, which is not conducive to laying ducks maintaining vigorous reproductive function, so artificial lighting should be supplemented. The daily lighting time must not be less than 16 hours, and the light intensity should be kept stable. Generally, one 40-watt light bulb is installed in a 20 sq m duck house, with a lampshade above the bulb, equal spacing between lamps, a hanging height of 2 m, and the bulbs kept clean. The lighting method can be to turn on the lights at dawn, turn them off at sunrise, turn them on at sunset in the evening, and turn them off after supplementing to 16 hours.

????3. Control fattening.

In autumn, food in the wild is abundant, and ducks easily find food to eat. If they are full and not allowed proper activity, the ducks will become too fat and lay fewer eggs. Therefore, in autumn they should be allowed a certain amount of exercise to stay physically strong, and their body weight should be controlled at 1.5-2 kg to encourage them to lay more eggs and larger eggs. However, when the ducks go out for exercise or play in water, attention should also be paid to the invasion of autumn rain and cold wind. If they are drenched by autumn rain and blown by cold wind, laying ducks will stop laying, and some may even become ill.

????4. Prevent cold and keep warm.

After the beginning of autumn, each time the wind blows, the temperature drops. A sudden drop in temperature will cause a large decline in the laying rate, so in production the range of microclimate changes in the duck house should be reduced as much as possible. Therefore, the work of preventing cold and keeping warm in late autumn should be done well, and it is best to keep the duck house temperature at 13°C-20°C. At the same time, the laying duck shed should be kept dry.

????5. Forced molting.

After late autumn, the egg production of ducks gradually declines and the eggshells become thinner. At this time, the method of artificial forced molting can be used. That is, pluck the large feathers from the ducks' wings and tails, and at the same time increase the feeding of concentrated feed and vegetable leaves. Generally after 7-8 days, new feathers grow on both wings and the tail of the ducks, while the feathers on the chest fall out naturally. After about 20 days, the feathers gradually grow in fully, and the ducks can resume laying.

????6. Keep the environment quiet.

Laying ducks have regular habits. After eating, they bathe and rest, do not run around, and lie still quietly when resting at night. Therefore, the operating procedures and the feeding environment should be kept stable and quiet, and the ducks' daily routine should not be disrupted, so that the laying ducks maintain good laying performance.
