What is the reason why laying ducks produce sand shell eggs? It is usually caused by lack of calcium, and the main ingredient of eggshell is calcium. Then how to treat the egg duck laying sand shell eggs?

When the proportion of thin soft shell eggs increases, 0.1% calcium can be gradually increased in the diet, and the change of eggshell thickness can be observed at any time. If the shell thickness increases, it indicates calcium deficiency. If the eggshell deformity increases, indicating a lack of vitamin D3, it should be supplemented. Check the dietary formula and adjust the content of calcium and phosphorus in time. Strengthen the feeding and management to keep the environment of the duck house quiet. When preparing the feed for laying ducks, it is necessary to have both fast and slow calcium sources. Stone powder and shell powder are usually used as calcium sources at the same time.

Ducks usually lay eggs in the early hours of the morning, so ducks must be made to maintain a high concentration of blood calcium in the early hours of the morning, otherwise they will produce sand shell eggs, deformed eggs, and even a decrease in egg production.

1. Lack of calcium in diet, or imbalance of calcium and phosphorus, or lack of vitamin D3.

2. With the continuous high yield for a long time, it is difficult to supplement the calcium from the feed.

3. The ambient temperature is too high, the ducks lose their appetite, eat less feed, and calcium is in short supply.

4. The duck is frightened, which disturbs the nervous function and endocrine gland function, which hinders the formation of calcium in eggs, or eggs are excreted too quickly to produce soft-shell or thin-shell eggs.

5. The stress factors caused by the crowding in the duck house are heavy ammonia, poor ventilation and uncomfortable laying of soft-shell eggs in the duck house.
