Recently, the CPI has risen rapidly, and the price of eggs has also risen. If laying hen farms want more income, it may be a realistic choice to increase the egg laying rate. So what factors affect the egg laying rate?
During this period, laying hens have basically eaten the new corn harvested in the same year, but the new corn has high water content and is prone to mildew. Poor eggshell quality, decreased feed intake, and high feed returns can seriously cause laying hens casualties.
Second: feed nutrition
When the temperature drops, the heat dissipation of chickens will be accelerated. In order to maintain body temperature, chickens have higher energy requirements, and at the same time will increase the loss of protein feed. If the nutrient concentration in the feed is low or does not meet the normal physiological needs of laying hens, it will cause Egg production declined. In addition, insufficient supply or poor absorption of calcium, phosphorus and vitamins in the feed will also cause problems of egg production rate and eggshell quality.
Third: stress response
Sudden changes in the lighting program, such as sudden light stop or reduction, reduced light intensity, etc.; the flock is suddenly attacked by cold currents, and prolonged low temperature; some adverse stimuli, such as abnormal sounds, wild birds and small animals suddenly enter Coop and cause fright, etc.
How to increase egg laying rate
The performance of laying hens and the level of laying rate are affected by physiological factors of laying hens, including hormone levels in laying hens, such as follicular estrogen, luteinizing hormone, coordination of fallopian tube and ovarian function in laying hens, and egg production. The level of free radicals in chickens, etc.
Generally, in the middle and late stages of laying hens, increasing the secretion of reproductive-related hormones such as follicle-stimulating hormone, luteinizing hormone and progesterone can improve the laying rate of laying hens.
Therefore, in order to maintain a high egg production rate, laying hens need to maintain a good physiological state. From the perspective of regulating the physiology of laying hens, farmers can adjust the secretion skills related to follicle maturation, ovulation and egg formation to improve laying hens. egg production rate.
During the breeding process, it is necessary to pay attention to whether the feed fed is mildewed. Now the new corn is more prone to mildew when the moisture content is large, and many diseases are introduced from the mouth. Observe the weather changes in time to avoid the sudden decrease of the weather and the failure to respond to the problem of the temperature difference in time, which will cause stress and epidemic prevention to poultry. In addition, when the weather turns cold, it is necessary to replenish energy for laying hens in time. A good egg-laying environment is also very important. Try to enter and exit the chicken house at the same time as possible to reduce the impact of noise on egg-laying period.
