Points for attention in Egg Duck breeding in Autumn

? 1. Adjust the diet and feed it 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 proportion of calcium and phosphorus and trace elements. The nutrition level of general autumn duck diet is crude protein 18%, methionine 0.3%, lysine 0.7%, crude fiber 8%, calcium 3%, phosphorus 0.6%. The amount of concentrate used for feeding autumn ducks should depend on the laying rate of the ducks. If the laying rate of the ducks is more than 50%, more concentrate can be added. Otherwise, you can feed some green feed, or increase the amount of bran in the concentrate, and reduce the amount of carbohydrate raw materials at the same time.

? 2. Replenish the light.

The natural light time in autumn is gradually shortened, which is not conducive to laying ducks to maintain strong reproductive function. Artificial light should be supplemented, the light time should not be less than 16 hours per day, and the light intensity should be stable. Generally, 20 square meters of duck house is equipped with a 40-watt bulb with a lampshade on top, and the distance between the lamp and the lamp is equal, and the suspension height is 2 meters to keep the bulb clean. Lighting can be used to turn on the lights at dawn in the morning, turn off the lights at sunrise, turn on the lights at sunset at night, and make up for 16 hours to turn off the lights.

? 3. Control the weight gain.

There is plenty of food in the wild in autumn, and ducks are easy to find food. if they are full and do not let them move properly, it will lead to less eggs laid by overweight ducks. Therefore, in autumn, they should be allowed to maintain a certain amount of exercise, keep their physique strong, and control their weight at 1.5-2kg, so as to promote them to lay more eggs and lay big eggs. However, when ducks go out for sports or playing in the water, they should also pay attention to the attack of the autumn rain and cold wind. If they are drenched in the autumn rain and the cold wind blows, the egg ducks will stop production, and some of them will even get sick.

? 4. Keep out cold and keep warm.

Once the wind blows in autumn, the temperature will drop once, and the sudden drop in temperature will lead to a substantial decrease in the laying rate. In production, the change of microclimate in the duck shed should be reduced as much as possible. Therefore, in order to prevent cold and keep warm in late autumn, it is best to keep the temperature of duck house at 13 ℃ ~ 20 ℃. At the same time, keep the egg duck shed dry.

? 5. Forced molting.

After late autumn, the egg production of ducks gradually decreases and the eggshell becomes thinner, so the method of forced molting can be used. That is, pluck the duck wings and tail of the large hair, while feeding concentrate feed and vegetable leaves. Generally speaking, after 7-8 days, the duck will grow new feathers on its wings and tail, and the feathers on its chest will fall off naturally. In about 20 days, the feathers will gradually grow up, and the duck can resume laying eggs.

? 6. Keep the environment quiet.

Egg-laying ducks live a regular life, bathing and resting after eating, not running around, and lying still at night. Therefore, it is necessary to maintain the operation rules and feeding environment stable and quiet, do not disrupt the duck's life law, so that the laying duck to maintain a good laying performance.
