How to reduce the breakage rate of eggs

Under normal circumstances, the average egg breakage rate is 6-8%. Improving eggshell quality and reducing egg breakage means increasing economic income. There are many factors affecting the breakage rate of cage@#@230@#@eggs, such as equipment factors, management factors, genetic factors, nutrition factors, etc. Corresponding measures should be taken according to specific conditions in the breeding and management process.

1, cage specifications should conform to the production characteristics of caged layers, when conditions permit, the selection of single cage single chicken cage can not only reduce the damage rate of eggs, but also help to play the production performance of chickens. The iron wire of the cage bottom net should not be too thick, and should have good elasticity to ensure that the eggs can be rolled out smoothly and at a suitable speed. For chicken cages with thicker and less elastic bottom nets, a layer of plastic net pad can be added to the bottom net.

2, as far as possible to prevent shock group; at least 4 times a day to pick up eggs, in order to reduce the collision and pollution of eggs; if artificial insemination, the operation should be gentle, do not rough; the best egg tray, egg tray when moving to take gently, gently put.

3. Calcium content in diet shall not be less than 2.5%, total phosphorus shall not be less than 0.65%, and total phosphorus level shall be reduced to 0.45% in the late laying period of chickens, so as to ensure that the ratio of calcium to phosphorus is close to 3.5:1, otherwise it will affect the absorption of calcium by the body. In addition, calcium should be added to the diet in the form of shells or coarse limestone in the late laying period of chickens, because this particulate calcium leaves the muscle stomach slowly and has a good effect on strengthening the eggshell growing at night.

4, in the high temperature environment, on the one hand, as far as possible to reduce the temperature and humidity in the house, on the other hand, to increase the concentration of protein, vitamins and minerals in the diet, to prevent laying hens due to reduced feed intake caused by nutritional deficiency. Vitamin C can promote calcium secretion from bone marrow, but also activate other vitamins, so in some stress conditions to lay chicken vitamin C, not only help improve the quality of eggshells, but also increase egg content, improve egg quality. Adding 0.5% sodium bicarbonate to the diet of laying hens in high temperature season can also effectively alleviate the egg shell quality problem in this period.

5, some varieties of layer damage rate is higher, eggshell strength is poor, so in the selection of introduction attention can not be introduced.

In short, to reduce the rate of broken eggs, mainly to improve the structure of chicken houses and strengthen the nutrition of laying hens, while strengthening management.
