The poultry equipment manufacturers have discovered that there are many reasons for the damage of eggs caused by careless management in the daily process of raising chickens. The eggs are affected by the health of the chickens, and the hardness of the eggshells will also be different due to the health and quality of the chickens. , Here are some methods for farmers to prevent egg breakage and the causes of breakage.

1. After the start of laying, as the week age increases, the surface area of the egg will also increase, and the strength of the egg shell will decrease. Therefore, the older the laying hens, the higher the breakage rate. The egg-laying posture of the chicken. Different qualities and postures when laying eggs will vary among individuals. For caged chickens, standing or squatting higher, than lying or squatting lower, the egg breakage rate is higher. Time of laying eggs. The hen lacks the light needed to absorb calcium at night, and the eggshells formed are thinner, so the breakage rate of eggs laid in the afternoon is lower than that of eggs laid in the morning. Health status. A variety of diseases have an impact on the quality of eggshells, such as infectious bronchitis, which can cause abnormal egg structure, irregular shape, and increase the rate of egg breakage.
2. Among the nutrition nutrition, calcium, phosphorus and vitamin D have a greater impact on the quality of eggshells. Under normal circumstances, the calcium requirement in the diet of laying hens should be 2.7-3.75%, which is 3-4 times larger than the 0.9% calcium requirement of non-laying hens. The phosphorus content should be 0.5%. Vitamin D can promote the absorption of calcium and phosphorus. For example, in the absence of vitamin D, even if the laying hens are fed rich calcium and phosphorus, soft-shelled eggs will be produced.
3. Environmental changes The temperature of the chicken house has a greater impact on the eggshell. The higher the house temperature, the more damage the eggs will be. In summer, the eggshells of eggs laid by chickens are usually about 5% thinner than eggs in other seasons. This is mainly because high temperature will reduce the chicken's feed intake and the corresponding decrease in calcium intake. In addition, in a high-temperature environment, if the relative humidity is high, the heat dissipation of the chicken is not good, and the egg will be damaged even more.
4. the sense of responsibility of the management staff. This is a major factor. When picking up eggs, placing eggs, moving egg boxes, and weighing, whether they are handled with care and handling has a great impact on the breakage rate of eggs. Daily management. Excessive rearing density, delayed egg picking, few laying boxes, and too little bedding will increase the breakage rate of eggs. Improper vaccination. Such as vaccination during the laying period, due to immune response, within a few days after vaccination. In addition to the drop in egg production, the breakage rate of eggs will also increase.
5. The type of battery layer cages. Due to the difference in the arrangement of the cage and the passage of the eggs through the egg trough, the damage rate will also be different. Generally, the damage rate of a single-layer cage is higher than that of a multi-layer cage. The reason is that two rows of cages share one egg trough and egg trough. It is located under the material trough, and it is not easy to find and repair in time once a failure occurs. The iron wire of the bottom net of the cage is too thick, the elasticity is poor, the inclination is not enough, or the egg trough of the lower cage is often subjected to collision, deformation, bending, pressure welding, broken ends, the egg collection belt is skewed, and there is no egg protection under the front net of the cage. The eggs in the upper cage or the upper cage are pecked by the chickens in the lower cage, especially the ladder type, which often increases the breakage rate of the eggs.
