What is the "pouring egg" of egg duck and how to prevent it?

Female ducks are called laying ducks from the beginning of laying eggs to the end of elimination. The utilization period of general egg-type sesame duck is about 350 days (150-500 days old), which is called the first laying year; some are reused in the second and third year after molting, but their production performance decreases year by year and should not be retained. Nowadays, the demand for duck eggs is increasing, so the breeding techniques of laying ducks are getting more and more attention. Laying duck "pouring eggs" has seriously affected the egg production efficiency of laying duck breeding, so egg duck farmers should pay special attention to it. Next, let's take a look at what the egg duck "pour the egg" is and how to prevent it.

What is "pouring eggs" in egg ducks?

Egg-laying ducks "pour eggs" means that female ducks raised in spring enter the laying period from November, when the temperature gradually gets colder, the temperature difference between day and night is too large, or due to lack of nutrition, egg-laying ducks stop laying "vacation". If the laying duck begins to change its hair when it pours its eggs, it will not be able to lay eggs until next spring.

How to prevent and cure egg duck "pouring eggs"?

When ducks show signs of "pouring eggs", such as smaller eggs, thinner eggshells, delayed feeding of eggs, wet feathers on shore, and drilling into the duck shed, the following measures should be taken in time:

Adjust the duck flock

In early winter, the old, weak, sick and disabled ducks in the flock will be eliminated in time, leaving female ducks with good production performance and strong physique. At the same time, properly raise more male ducks to chase each other and increase the amount of exercise of the ducks.

Feed more protein feed

Properly increase the proportion of corn, broad bean and bean cake to control the feed intake of ducks and improve the nutrient concentration of feed.

Protect against cold and keep warm

The holes in the duck shed should be blocked, the doors and windows should be hung with straw curtains, and the floor of the shed should be padded with soft thatch and straw to ensure that the belly of the duck does not catch cold. At the same time, we should also pay attention to do a good job of health and epidemic prevention to ensure the health of laying ducks.

Supplementary lighting

The laying duck needs 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, it is necessary to install a 40-60 watt bulb in the duck shed (one for every 20 square meters). The bulb is 2 meters high from the back of the duck, and covered with a lampshade, so that the light is concentrated on the duck body, and the light should be uniform for 3 to 4 hours every night.

"rush to the shed"

"driving the shed" can enhance the cold protection and digestive ability of laying ducks, and prevent laying ducks from stopping production. The practice is to gently yell at the ducks in the duck shed to start, slowly do circular movement in the same direction, generally go around 4 ~ 5 circles at a time, catch up every 1 hour, and catch up 2 ~ 3 times a day. Especially before driving ducks into the water, we should also "drive the shed". When more than 80% of the ducks quack loudly, the shed can be opened to release the ducks into the water, so as to improve the ability of the ducks to adapt to the temperature and water temperature outside the shed.

Add cod liver oil

Cod liver oil is rich in vitamins An and D, which is good for enhancing duck immunity and stabilizing egg laying rate. Specific feeding method: 1 ml per duck per day, first mix cod liver oil in 1.5 kg wheat bran, then mix well in feed, after 3 ~ 5 days, if the eggs are normal and feathers are bright, you can stop feeding, which will affect the economic benefits.
