How to reduce the egg breaking rate of laying hens? Many laying hen manufacturers have such doubts. Compare when using layer cage equipment. Many cannot be solved directly. Here are some solutions

1. To meet the nutritional needs, especially the content of calcium and vitamin D3, the content of phosphorus should be appropriate, and the ratio of calcium and phosphorus should be mastered, which is generally around 3.4-4.6:1.

2. Increase the number of egg inspections and avoid collisions with each other, especially during the concentrated egg-laying time, and light actions should be taken when picking up and moving eggs.

3. In the high temperature season, increase the calcium content in the diet appropriately, the calcium content is between 3.7-5%, and should not exceed 5%, and add baking soda (0.25% sodium bicarbonate instead of 0.2% salt) to the drinking water and Vitamin C (50-100 mg/kg) can both reduce heat stress in chickens and improve eggshell quality.

4. The number of egg-laying boxes for flat chickens should be sufficient, and the bottom of the cage should be covered with clean and soft cushions; the bottom of the cage should not be too steep, and the lead wire should not be too thick. Cushioning is used on the sloped turns of the egg line.

5. From 50-60 weeks of age, a short-term fasting for 3-7 days was performed, the egg production was the same as that of the non-fasting group, the eggshell strength was significantly increased compared with the non-fasting treatment, and the egg breaking rate was greatly reduced.

6. To keep the flock healthy and not get sick, many diseases will not only reduce the egg production rate, but also reduce the quality of the egg shell, causing the egg breakage rate to increase.

7. For brown-shell hens with good eggshell quality, the breakage rate of brown-shell eggs is lower than that of white-shell eggs.

8. Reduce the occurrence of stress factors and keep the environment inside and outside the house quiet and comfortable.
