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 temperature difference between day and night in spring is large. It is necessary to pay attention to controlling the constant temperature. If the temperature is too high or too low, the weight of the broiler will be affected. The weight of the chicks should be 4 times of 7 days after entering the house. If this standard is not met, it will affect the growth and development of broilers. If the temperature exceeds 38 ° C for more than 3 hours in the first week of brooding, it will affect the growth and development of the chicks.

(1) Temperature control before chicks enter the poultry farming cages.

Be sure to fully pre-warm the brooding room, preferably more than 12 hours in advance, to keep the temperature of the air, floor and wall of the house consistent. In production practice, the temperature of brooding is not up to standard. Although the temperature in the air has reached the required level, the ground temperature is still relatively low. It is easy to appear cold on the second day after entering the chick. Although it can be adjusted, the late chicks tend to The intestinal tract is not good.

(2) Pay attention to temperature control during immunization.

Every immunization should control the temperature, preferably 2 ° C ~ 3 ° C higher than usual, due to the weak immunity of the body during immunization, it is easy to infect mycoplasma or E. coli disease, so during this period the house should be suitable temperature.

Farmers who raise layer hens in poultry chicken cages all want to allow chickens to lay more eggs, but some of them have low egg production rates due to some reasons. Today we will discuss the reasons.

First of all, there are two reasons for the lack of egg production rate: feed and management. Farmers need to check whether the feed formula is nutritionally balanced, and check whether the temperature and humidity of the poultry house are in line with the growth conditions of laying hens.

Farmers also need to reflect on the rapid change of feed after the peak egg production period. This will cause the chicken to have a greater stress response and affect the chicken's feed intake. As a result, the nutrients obtained by the chickens are reduced and the egg production rate is reduced.

The other reason is that the noisy environment of the chicken house causes the flock to be agitated. For example, loud noises can easily frighten chickens. Or suddenly change the breeding environment, etc. In response to the above problems, farmers should strengthen the management of the chicken house breeding environment and solve the problems in time.

Farmers need to consider whether the chicken house has sufficient light. Because light has a greater impact on stimulating the physiological functions of the gonads and laying eggs. Some chicken farmers only use natural light instead of lighting, so that the light is below 16 hours. Some have supplemented the light, but the light bulb is too small or the degree is too small. Although there are 15W light bulbs, they are not cleaned in time and are covered by dust, etc. And the light is not enough, which adversely affects the egg production rate.

The above is the summary of the reasons why laying hens lay fewer eggs. I hope that all farmers who raise layer hens can use the battery cages for layer hens to summarize the above experience to better raise chickens.

The use of a full range of chicken equipment is becoming more and more popular in the chicken industry, and its advantages in the breeding process are becoming increasingly clear. Now, we will not introduce the advantages of the farmers in use. Today, we mainly bring farmers to understand some of the equipments included in the complete chicken equipment, so that farmers can know what to do when they purchase equipment. Easy to buy.

Chicken battery cages: chicken battery cages is the most basic equipment in the complete chicken equipment is also a must. Whether it is raising broilers or laying hens, you need to buy them. When using cages, the amount of culture can be increased and the area of the house can be saved.

Manuring system: The manuring system mainly refers to the manure removal machine. The manure removal machine is divided into a scraper manure removal machine and a belt manure removal machine. Both types of manure removal equipment can clean the faeces in the house and reduce air pollution. When the farmer purchases, he can choose the appropriate type of manure removal machine according to his own feeding situation.

Feeding system: Feeding system refers to the feeding machine. Farmers can feed the prepared feed with comprehensive nutritional value directly. The feeding machine can also control the feeding amount of the feed and ensure the chickens. The uniformity of the diet.

Ventilation and cooling system: The main ventilation and cooling system used in the house is the fan and the wet curtain. The scientific installation method uses the negative pressure to reduce the temperature inside the house. This will create a good living environment for the flock.

The egg-colletor: The egg-collector machine is mainly used in the equipment for breeding laying hens. The egg-collector machine can help the farmers to raise eggs, increase the number of eggs, and reduce the breakage rate of the eggs, thereby improving the economic benefits of the farmers.

The above is an introduction to the various equipment in the complete chicken Poultry Equipment for Sale. I hope that through the introduction today, the farmers can provide some help for the equipment.
