Cold weather insufficient nutrition beware of laying ducks stopping laying in early winter

Egg duck "pour eggs" refers to the spring female duck in November into the laying period, and at this time the weather gradually becomes cold, day and night temperature difference is large, such as insufficient nutrition, resulting in just laying eggs duck production phenomenon. When duck eggs appear small, eggshell thinning, egg laying time delay, wet feathers after feeding or swimming, etc., measures should be taken in time:

Adjust duck flock: In early winter, timely eliminate old, weak, sick and residual ducks in duck flock, leaving behind female ducks with good production performance and strong physique. At the same time, more appropriate breeding some drakes, so that they chase each other, increase the amount of exercise laying ducks.

Improve feed nutrition level: increase the proportion of corn, broad bean and soybean cake in diet appropriately, control feed intake of laying ducks, and improve feed nutrition level.

Cold and warm: duck shed holes blocked, doors and windows hung with straw curtains, the shed floor mat thick dry soft thatch, straw and other things to ensure that duck abdomen does not suffer from cold. At the same time, relevant epidemic prevention work shall be done to ensure the health of laying ducks.

Supplementary lighting: laying ducks need 16 hours of light every day during the laying period. In winter, the day is short and the night is long, and the light is obviously insufficient. Therefore, 40~60 watt bulbs (one for every 20 square meters) are installed in the duck shed. The bulb is 2 meters high from the duck back, and the lampshade is covered to make the light shine on the duck body. The light should be uniform and shine for 3~4 hours every night.

Noise duck: noise duck can enhance the ability of laying duck to keep warm and digest, prevent laying duck from stopping production. Gently shout ducks to start in the duck shed, slowly move in a circle in the same direction, generally 4~5 circles each time, once every hour, 2~3 times a day. Especially before the duck enters the water, it should also be noisy duck. When more than 80% of the ducks loudly "quack" call, can open the shed to put duck water, in order to improve the duck outside the shed temperature and water temperature adaptability.

Add cod liver oil: cod liver oil is rich in vitamin A and vitamin D, can enhance the immunity of laying ducks, stable egg production rate. Specific feeding method: feed 1 ml per duck every day, first mix cod liver oil in bran, then mix well in feed, feed for 3~5 days, if laying duck lays eggs normally, feathers are bright, you can stop feeding.
