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.

1. Medium-scale chicken farms will become mainstream

At present, the long-term "small-scale and large-group" breeding in the layer industry has made disease control in areas with dense layer production become the biggest factor affecting the development of the industry. In the next 5-10 years, chicken farms with a stock of 50,000 to 500,000 layers will become the main source of eggs in the future, and chicken farms with a stock of less than 10,000 will gradually withdraw from the layer breeding industry.

2. Intelligent breeding

With the development of the poultry breeding equipment manufacturing industry and the integration of breeding equipment from countries around the world in the past two years, competition in the breeding equipment industry has become increasingly fierce. The relative investment of breeding equipment in the entire breeding process is constantly decreasing, which has made automated chicken coops popular all over the world. Coupled with the continuous increase in labor costs and management costs, farmers are actively developing in the direction of appropriate scale, standardization, automation, and intelligent breeding. "Man manages machines and machines raise chickens" will become more and more common, and intelligence will inevitably become the industry's choice in the future.

3. Industrial integration

With the scale and modern development of the layer industry, the integrated operation model has gradually been accepted by the majority of chicken farmers. The formation of a completed industrial chain will be very benign to the development of the entire industry. There are specializations in the technical industry, and professional people do professional things. The operation model from breeding-breeding chickens-feed-equipment-animal protection services-brand eggs-egg processing-out of the chicken industrial park is a good model for building a complete industrial chain.

Therefore, it can be seen that the use of automated poultry farming equipment to raise chickens is the general trend.

The layer battery equipment manufacturers tells the advantages of the layer cage. Do you know any advantages of the layer cage? is that clear? It doesn't matter if it is unclear. Let's talk about the breeding advantages of layer cages.

Chicken farmers should know that chicken cages play a big role in the process of breeding. Especially the layer battery cages, it is a good protection for eggs, let's take a look at some of the advantages of laying chicken cages.

The equipment plays an important role in the breeding, especially in the laying of laying hens. The first part of the laying hen cage and the cage door show its advantages. The density of the cage and the angle of the egg are more and more manifested from these aspects. The benefits of chicken.

The benefits of the cage: the upper and lower cages are completely staggered, often seen in 2 to 3 layers. The advantage is that there is no need to set up a dung board at the bottom of the cage. For example, the manure pit may not have a clearing system. The structure is simple, and the ventilation and illumination areas of each layer are large.

1. The mesh of the egg cage is relatively smooth, which can prevent the chicken from being injured in the foot.

2. The egg cage and the bottom net are encrypted, which can effectively prevent the fatigue of the ankle and laying hens.

3. The mesh of the egg cage is galvanized, which can improve the service life of the chicken cage. Generally, it can be used for 10 or 15 years.

4. High-density feeding of egg cages is more economical, and is conducive to epidemic prevention, and can also reduce the incidence of poultry diseases.

5. The unique door reinforcement design of the egg cage can effectively prevent the chicken from wasting feed when eating. And because the cage door space is increased, it is more convenient to manage the chicken.

Now that science and technology are advanced, people's breeding is becoming more and more standardized, and more and more chickens are raised using poultry chicken raising equipment. So how should we manage the use of battery hen cages before laying eggs?

First of all, we must feed scientifically, do not increase or decrease the feed at will. The main reason for the change of feed for laying hens is that the production chickens need calcium supplementation.

If calcium is supplemented too early, the growing chicken will not have the absorption function. If calcium supplementation is too late, it may cause poor egg shell quality. Some farmers are always blindly confident and increase or decrease feed at will. This may cause the egg production to not become a scientific curve and affect the income of farmers. Therefore, farmers must insist on scientific feed feeding.

Secondly, scientifically increase the light time. After entering the laying period, the light time should be extended in the chicken house, and the light time should be gradually increased according to the weight of the laying hens from 18 weeks to 20 weeks of age. After the longest exposure time is 15-16 hours, it remains unchanged. Some farmers always want to advance the egg laying time and increase the light time at will, which may affect the laying cycle, and the gains outweigh the losses. Therefore, farmers must follow the scientific rules and gradually increase the light time.

Finally, maintaining a quiet environment in the chicken house is crucial. As we all know, the harsh noise of chickens, especially the laying hens, must keep the chicken house quiet to avoid excessive reactions. After laying the first two eggs, the laying hens are extremely excited, and even behave a little nervously or move abnormally. At this time, it is necessary to keep the chicken house as quiet as possible to avoid disturbing the laying cycle.

The above is the summary of how the layer cages should be managed before the laying hens lay eggs. Hope that the farmers can manage the chicken coop well.
