Light is one of the necessary environmental conditions for laying hens. The intensity, time and color of light are very important for chicken activities, metabolism, growth and productivity, especially for laying hens raised in layer battery cage equipment. Reasonable control of light can improve the production capacity of laying hens and the economic benefits of farmers.

1. The effect of light on laying hens

Light stimulates the hypothalamus directly through the skull or light through the nerve pathway of the nerve lobe. After the hypothalamus is stimulated, it secretes gonadotropin-releasing hormone, which reaches the anterior pituitary through the pituitary portal system, causing follicles The secretion of stimulating hormones and ovulation hormones promote the development of follicles and then ovulation. The developing follicles produce estrogen, which promotes the development and function of the hen’s fallopian tubes. At the same time, estrogen also promotes calcium metabolism to facilitate the formation of eggshells. Ovulation hormones Causes hens to ovulate. In a closed chicken house, no matter how nature changes day and night. The laying of eggs by hens is mostly concentrated in the first 2-7 hours of artificial light.

2. Control of lighting technology

1. Lighting time. The length of lighting time is closely related to the age of sexual maturity of chickens. Too short light time during the rearing period will delay sexual maturity, and too long time will lead to early sexual maturity.

2. Light intensity. Appropriate light intensity is conducive to the normal growth and development of chickens. Excessive light can make chickens irritable and cause severe pecking, prolapse or nervousness. The sudden increase in light intensity during the laying period can significantly increase the rate of cracked eggs, soft-skinned eggs, deformed eggs, and sudden death; low illumination can accelerate the deposition of body fat, but the illumination is too low. It will reduce the chicken's feed intake, reduce drinking water, hinder growth and development, and reduce egg production.

There are four ways to control the light intensity: one is to control the intensity by increasing or decreasing the number of bulbs; the other is to adjust the intensity by changing the bulbs of different power; the third is to control the intensity by adjusting the voltage; the fourth is to control the intensity by adjusting the spacing. But no matter how you adjust, each time you turn on and turn off the lights, you must gradually change from dark to bright, from bright to dark, to give the chickens an adaptation process to prevent frightening the flock. The distance between the bulbs should be 1.5 times the height of the bulb from the ground; the distance between the lamp and the wall should be half the distance between the bulbs, and the lamps between rows should be arranged in a staggered manner to obtain a more uniform lighting effect.

3. Light color. Laying hens are more sensitive to color. Chickens have better vision under red, orange and yellow light. Under red light, it tends to be quiet, with very few pecking habit, a little later in maturity, high feed reward, and egg production slightly increased; yellow light reduces feed reward, delayed sexual maturity, increased egg weight, decreased egg production, and increased pecking ; Green light can make sexual maturity earlier and weight gain faster; blue light can reduce hen egg production.

The right temperature of the chicken house can exert greater production potential for chickens. The quality of environmental control directly affects the success of breeding. Therefore, temperature control is an important factor in feeding. The following chicken breeding equipment manufacturers explain the main points of chicken house temperature control.

In the environmental control of the layer hen chicken house, the layer chicken can obtain a higher survival rate, weight gain speed and feed remuneration in the above-mentioned suitable temperature environment. Whether the specific temperature of each brooding is appropriate or not is determined by the dynamic performance of the chicks:

When the temperature is appropriate, the chicks are evenly distributed indoors, lively, with smooth feathers, and close to the body surface. They are relatively quiet during sleep and scramble to eat.

When the temperature is too low, the chicks will show low temperature performance. The chicks will be crowded near the heat source or in a certain corner, their feathers will be fluffy, the spirit will be wilted, and they will make continuous calls. This way for a long time, it is easy to cause the chicks to catch a cold or be crushed to death. It must be heated immediately and the crowded chicks must be dispersed.

When the temperature is too high, the chicks stay away from the heat source, spread their wings and lie down, panting, and rush to drink water. There is often no water in the drinking fountain, but the fluff is wet. Over time, the physique of the chicks will be weakened, growth will be hindered, and even heat death will be caused. When the temperature is too high, the temperature should be gradually lowered, but be aware that a sudden drop in temperature can cause a cold.

Therefore, attention must be paid to the temperature control of the chicken house during the entire feeding period of the laying hens. A thermometer can be placed in an appropriate place in the house for observation, and certain measures can be taken to cool down or adjust the temperature. In the hot season, when the temperature in the chicken house is high, you can open the doors, windows and vents, turn on the fan or exhaust fan, increase the ventilation in the house, and lower the temperature in the house. When necessary, cold water can be sprayed on the ground or sprayed on the roof to cool down.

The use of poultry battery layer hen cages to raise chickens requires more attention to the living environment of the chickens in the hen house. Provide a suitable temperature environment for the chickens so that they can grow healthier.

In recent years, with the vigorous development of the chicken industry, the improvement of the research and development level of livestock breeding equipment has greatly promoted the development of automation, and the technology of chicken farming equipment has also achieved rapid development.

Because of the sharp increase in labor costs, among the modern chicken raising equipment, the most widely used is the stacked chicken cage, which has been recognized by the majority of farmers.

Therefore, a modern-scale chicken farm cannot be separated from the use of modern intelligent chicken-raising equipment. Modern intelligent chicken-raising equipment can be said to be the core of the normal operation of modern-scale chicken farms, while fully automatic battery chicken-raising equipment is a modern layer chicken farm. Indispensable basic equipment for breeding.

The battery chicken cages are a product that solves chicken raising equipment at one time. The cascading brooding cage is a product equipment that can be used for brooding. There is no need to replace the chicken raising equipment during the chicken raising process, which avoids the stress reaction of the chicken during the transfer of the chicken, and also reduces the labor cost for the farmers. Laminated chicken cages are made of hot-dip galvanizing technology and have been treated with anti-corrosion treatment. It is necessary to pay attention to daily maintenance. The service life will be very long, and the multi-layer design can raise a large amount at the same time and does not occupy space. The cascading brooding cage can be raised in a centralized manner. There is a matching nipple drinking system, which can set different drinking water according to the size of the chicken, and the cage is convenient to wash and easy to disinfect.

The extensive use of modern chicken farming equipment has improved the efficiency of breeding, and farmers can more easily realize intensive chicken breeding because of their use.

For chicken farmers, the peak period of egg production will always be encountered at some stage of the year. Under normal circumstances, laying hens begin their pre-production period from the age of 16 weeks, and enter the peak of laying eggs at the age of 25 weeks. Whether the feeding and management status during the peak period of laying hens meets the requirements of chicken growth and egg production will have a great influence on the egg production during the entire production period. Therefore, for chicken farmers, it is very important to manage the layer chickens during production.

It is advisable to complete the laying of the laying hens before the age of 18 weeks in order to make the chickens familiar with the environment as soon as possible. In order to adapt to the increase of chicken body weight, growth of the reproductive system and the demand for calcium, the laying hens can be fed at the age of 18 weeks and the culmination at the age of 20 weeks. The most suitable temperature for laying hens is 13°C～23°C. In winter, it is better to keep above 10°C. In summer, it is better to keep below 30°C. Maintain indoor air circulation and prevent various noises. Keep the environment and feeding, drinking, lighting and other stability.
