How to reduce the egg-breaking rate of caged layer

1. Improve feed quality Calcium, phosphorus content in the feed and the ratio between the two, calcium, phosphorus absorption rate, vitamin D3 content have a certain impact on the formation of the eggshell. (Calcium determines eggshell brittleness, phosphorus determines eggshell elasticity and toughness, and vitamin D3 affects eggshell thickness and strength.) As the egg production rate of the flock increases, the demand for calcium and phosphorus increases day by day in the diet. General feed should contain 3.0%-3.75% calcium, total phosphorus not less than 0.65%, calcium, phosphorus ratio between 4:1-6:1. (Too high and too low phosphorus levels have adverse effects on the quality of egg shells, too low phosphorus content reduces the elasticity of the shell, and too high phosphorus content affects the absorption of calcium.). In order to promote the absorption of calcium and phosphorus and the formation of egg shells, adding a quantity of vitamin D3 in the feed can add 0.01% to 0.015% of vitamin AD3 powder to the feed. In addition, the lack of manganese will also affect the strength of the eggshell. Normally, there are 55 grams of manganese per ton of feed. Fluoride and magnesium content can not be too high, it will make eggshell brittle.

2. The design and installation of cages should have a reasonable cage bottom slope of 8-9. If the cage is too small, the eggs are not easy to roll out. If the cage is too large, the eggs will roll too quickly and break easily. The two groups of cage connection use wire to connect the egg nets together so as to avoid cracks over the ambassador eggs. The cage must have high strength to prevent deformation during use.

3. If you want to diligently chop more eggs each day, you can reduce the cracks caused by collisions and reduce the damage caused by eating chickens. Usually, at least 2 eggs are quailed in the morning and at least 1 in the afternoon, and once again before the light is turned off in the evening, the number of broken eggs can be effectively reduced.

4. Keeping the health of chickens Infectious bronchitis, enteritis, atypical neoplasms, salpingitis, and other diseases can affect the quality of egg shells, cause eggshell thinning or uneven eggshell texture, and even appear soft eggs and Shellless eggs. Therefore, it is very important to regularly sterilize the environment inside and outside the house and do a good job of hygiene and epidemic prevention. It is very important to maintain the health of the flock.

5. Mitigating the effects of high temperature Chickens do not have sweat glands, and their whole body is covered with wool, which is difficult to dissipate and is easily affected by high temperatures. The production temperature of laying hens is 13°C-25°C. When the temperature exceeds 25°C, the eggshell tends to thin, and when the temperature exceeds 32°C, the rate of egg breakage increases significantly. You can install ventilators or ceiling fans to increase mechanical ventilation and maintain air circulation. It is also possible to hang wet curtains at the air inlet, or spray water on the roof to reduce the temperature inside the house.

6. To prevent frightening layer chickens are very timid, frightened, sudden sound, the replacement of feeders, sudden changes in feed, etc. can cause a frightening group of laying hens. The frightened laying hens may cause abnormal peristalsis of the fallopian tube, leading to the egg being formed in advance, resulting in an increase in the number of shells, soft eggs, or shellless eggs. Therefore, try to avoid or reduce the vaccination during the production of eggs to avoid the occurrence of sudden noise, so that the breeders, feeding methods, and formulated feed are fixed.

7. To prevent quail eggs because of poor feeding or management reasons, often appear quail egg chicken. In addition to diligent eggs, observe carefully and keep the chickens individually.
