How to reduce the egg breakage rate? Practical methods for poultry farmers to share

Under normal circumstances, the average egg breakage rate is 6-8%. Improving eggshell quality and reducing the egg breakage rate means increased economic income. Many factors affect the breakage rate of eggs from caged @#@230@#@, such as equipment factors, management factors, genetic factors, nutritional factors, etc. Corresponding measures should be taken according to specific circumstances during the feeding and management process.

1. The specifications of the cage equipment should conform to the production characteristics of caged laying hens. When conditions permit, choosing single-cage single-bird cages can not only reduce the egg breakage rate, but also help give full play to the hens' production performance. The wire of the cage bottom net should not be too thick and should have good elasticity to ensure that the laid eggs can roll out smoothly at an appropriate speed. For chicken cages with thicker bottom net wire and poorer elasticity, a layer of plastic mesh padding can be added on the bottom net.

2. Prevent flock panic as much as possible; collect eggs at least 4 times a day to reduce collisions between eggs and contamination; if artificial insemination is used, the operation should be gentle and never rough; it is best to use egg trays for loading eggs, and when moving egg trays, handle them gently and place them down gently.

3. The calcium content in the daily ration should not be lower than 2.5%, and the total phosphorus should not be lower than 0.65%. In the later stage of laying, the total phosphorus level should be reduced to 0.45% to ensure that the calcium-to-phosphorus ratio is close to 3.5:1; otherwise, the body's absorption of calcium will be affected. In addition, in the later stage of laying, calcium added to the daily ration should be supplied in the form of oyster shells or coarse limestone, because this granular calcium leaves the gizzard more slowly and has a very good effect on strengthening the strength of eggshells formed at night.

4. In a high-temperature environment, on the one hand, reduce the temperature and humidity inside the house as much as possible; on the other hand, increase the concentration of protein, vitamins and minerals in the daily ration to prevent nutritional deficiencies in laying hens caused by reduced feed intake. Vitamin C can promote the secretion of calcium from bone marrow and can also activate other vitamins. Therefore, under certain stress conditions, giving laying hens vitamin C not only helps improve eggshell quality, but also increases the egg contents and improves egg quality. In hot seasons, adding 0.5% sodium bicarbonate to the diet of laying hens can also effectively alleviate eggshell quality problems during this period.

5. Some breeds of laying hens have a higher breakage rate and poorer eggshell strength, so care should be taken not to introduce them when selecting breeding stock.

In short, to reduce the broken egg rate of eggs, the main approach is to improve the chicken house structure, strengthen the nutrition of laying hens, and at the same time strengthen management.
