How to fully master the skills of controlling high temperature and high humidity in chicken houses?
Higher temperatures in summer can lead to reduced appetite and reduced feed intake. As a result, the metabolic capacity of the chicken in layer battery cage, the nutrient intake of protein, vitamins and minerals is seriously insufficient, resulting in a decline in production performance. Therefore, dietary formula must be adjusted to meet heat stress. To meet the nutritional needs of chickens.
The caloric content of various nutrients varies greatly during digestion. Protein produces the most heat, and fat produces the least amount of heat. In order to reduce the heat dissipation burden of the chicken, the crude protein level should be reduced as much as possible to ensure the essential amino acid content and amino acid balance. Avoid excessive protein and increase the proportion of fat feed by adding fat. Heat stress in laying hens leads to reduced feed intake, resulting in insufficient energy intake.
Adjust the paper feed mode and lighting time. In the summer, the temperature is higher at noon, the appetite of chicken is low, and the temperature is suitable in the morning and evening. Chicken has a strong sense of hunger. At this point, the feed stimulates appetite, increases feed intake, and has a lower peak heat production. Time, because the maximum heat production related to digestion is 3-5 hours after feeding, should be avoided after 9 am to meet the nutritional needs of chicken production or growth, improve its anti-stress ability, broilers can rest the lighting system at night , low light illumination for 1 hour, light off for 2-3 hours, and so on. Egg laying hens can turn on the lights around 1 am, let the chickens heat up, drink water and feed, and the chickens start laying eggs when they are bright, so as to avoid laying eggs at high temperatures at noon. And reduce heat stress. It is estimated that 80-90% of consumption is consumed when it is cool. For free-fed broilers, two feeds can be supplied at the same time, one material is normal, the other material has a low nutrient concentration, and the chicken can be selectively eaten as needed. Tests have shown that this method can improve weight gain and feed compensation. Reduce the cost of feeding and mortality of poultry farming equipment for sale.
During heat stress, 80% of body heat is dissipated by evaporation. Try to stimulate the chicken to drink plenty of water to ensure that the drinking water is adequate and cool. Since low temperature water can carry away more heat in the body, it can relieve heat stress and reduce heat stress. The adverse effects of heat stress on feed intake. However, drinking water must be hygienic, preferably deep well water. When the house is exposed to high temperature and high humidity (temperature exceeds 35 ° C, humidity exceeds 70%), the following measures should be taken to prevent acute death. Close the wet curtain and turn on all fans to remove moisture from the house. When the humidity exceeds 80%, the side windows and doors in the front half of the house should be opened immediately, so that the air inlet area is larger than twice the area of the air outlet to achieve rapid dehumidification for poultry farm equipment suppliers.
Key points of light control technology for laying hens
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.
Maintenance and maintenance of automatic layer breeding equipment
If a breeding farm wants to be industrialized, large-scale breeding is inseparable from automatic layer breeding machinery and equipment. Automatic layer breeding machinery and equipment are good assistants to assist layer farmers in the breeding work. Nowadays, the chicken breeding equipment is very good. Mechanical automation can be applied for a long time. This requires farms to carry out timely maintenance and maintenance of machinery and equipment, so as to ensure that all machinery and equipment can be maintained for the long-term normal work of the farm. The working efficiency of the chicken farm is the maintenance and maintenance of the following automatic layer breeding machinery and equipment.
The key of automatic layer breeding machinery and equipment includes: automatic manure cleaning machine, automatic feeding machine, automatic egg picking machine, each of which will describe the key points of maintenance of machinery and equipment.
1. Automatic manure cleaning machine: After the farm has applied the manure cleaning machine for a period of time, the manure removal belt will increase and increase the slack. Maintenance of rolling bearings and rubber sticks. Rolling bearings should be added with unsalted butter on time. The glue sticks should be kept tight and not loose. In addition, many farms have a roll-up of manure removal opportunities. Farms will remove manure belts in passive rolling. The position of the barrel can be leveled.
2. Automatic feeder: When the feeder is in use, the farm must pay attention to the fact that no items can be placed on the feeder, otherwise it will cause the motor to withstand too much force and burn the motor. The application of the feeder Make sure that the transmission chain and gears have a certain level of lubrication, otherwise the lack of lubrication will destroy the equipment. The farm should pay attention to regular maintenance. The feeder is mainly produced by skin to transport concentrated feed, so the farm should be maintained regularly Is the transmission belt intact? Is the level of tightness moderate? The control cabinet of the feeder will have a lot of dust due to dust caused by the concentrate. In the long term, it will cause short-circuit failure of the internal power circuit. The farm should carry out the removal on time.
3. Fully automatic egg picker: When the farm uses an automatic egg picker, it is necessary to pay attention to the detailed learning and training of the appropriate operation steps of the machine equipment. If the wrong operation is very easy to cause damage to the machine and equipment, use the egg picker After that, you must pay attention to frequent disinfection and sterilization, because some chicken excrement, feather dusters and other items containing pathogens are inevitably left in the whole process of application of machinery and equipment. If you have been using a machine that carries pathogens and does not often clean up If the equipment is available, the quality of the eggs will be reduced.
Why modern chicken farming equipment is becoming more and more important？
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.
How to Manage Laying Hens Near egg Production Peak?
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.
Which Factors Affect Size of Eggs in Chicken Feed?
Studies have shown that within a certain range, the content of some trace components in eggs is significantly affected by chicken feed. The content of nutrients varies, which affects the quality and size of the eggs.
Protein and amino acid levels in feed, protein intake is the main nutritional factor that affects egg size. Adjusting the protein level of the diet can change the size of the egg. Each one increase or decrease in dietary protein levels, such as from 16% to 17% or 15%, can increase or decrease the weight of the egg by approximately 1.2 grams. In practice, it is best not to increase or decrease the protein by more than 1 percentage point each time. Amino acid nutrition is the essence of protein nutrition.
The effect of dietary energy levels on egg weight is mainly through feed intake. If the daily energy intake of layer hens is lower than the lower limit of the above values, the egg production and egg weight will be affected, and thus affect the protein's Food intake (or protein savings) allows hens to have higher protein levels for maintenance, egg production and increased egg weight.
Essential fatty acids play an important role in the factors that affect egg weight. Linoleic acid is involved in fat metabolism, so it affects the size of the egg through its effect on the yolk.
Attention Chicken Farming Points in Summer
- Do not mix the feed water with porridge-like chicken. Thinners tend to dilute the digestive juices and reduce the activity of various digestive enzymes, resulting in incomplete feed digestion, poor nutrient absorption, and even indigestion, which greatly reduces feed utilization. Chickens are also prone to fat deposits because of their thinner skin, and their subcutaneous fat is too thick to cater to consumer preferences.
- Try to use a free drinking fountain, or plastic cover drinking fountains, such as the use of plastic cover drinking fountains best hanging up, to the chicken can drink water is appropriate to ensure that the chicken has sufficient clean drinking water.
- When the weather is hot, it can be fed in the morning and in the evening and it can improve the feed intake of chickens. Wet material can be used at noon, and the ratio of material to water is suitable for 1:0.5-2. The degree of opening is better. Generally, feeding dry materials in the morning and feeding wet materials at noon can stimulate chickens to eat more food.
- When your chickens run into high temperature, you can add glucose and vitamin C to your drinking water, which can increase the energy lost due to lack of feed intake. It can also enhance the chicken's physique and anti-stress ability. It also has certain auxiliary treatment effects on high fever.
Temperature control management of spring broiler breeding
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.

What are the factors affecting the efficiency of laying hens?
Under the premise of consistent species of laying hens and feed ingredients, the most important indicator affecting the efficiency of broiler breeders is the laying cycle, followed by the feed-to-egg ratio, and again the feed price, egg production rate, egg weight, and dead scouring rate.
Of course, these indicators are not completely isolated, but are interrelated. The effective way to increase the efficiency of laying hens should first be to prolong the laying cycle; second is to design a reasonable level of metabolic energy in order to reduce the ratio of feed to eggs and control feed unit price.
Strengthen feeding and management of your layer chicken cages for sale, reduce the incidence of laying hens The health of laying hens must focus on the laying period, because this period is the most important stage for laying hens to achieve a good economic benefit, and it is also a period when laying hens are susceptible to disease.
Farming Points and Management For Free-range Chickens
Farmers can choose the right brooding season in order to facilitate the grazing of ecological chickens. The best season of farming is in March to May, when the survival rate of brooding is high. By the middle chicken stage, due to suitable temperatures and long hours of outdoor activities, it can be fully exercised and exercised, resulting in strong physique, which is very beneficial to natural grazing, feeding and prevention of natural enemies in the future. Spring chicks are sexually mature and have long duration of egg production, especially chicks hatching in early spring.
Feeds on ecological chickens must be organic feed. Therefore, when planting ecological chicken feed ingredients, it must comply with the requirements of organic foods, and animal feeding supplements that are artificially supplemented must also comply with the standards for the production of organic foods. It is forbidden to add chemicals during the production of artificial feed to ensure the quality of ecological chickens. The quality of natural feeds depends on the natural environment. There are natural forages, mature fruit and various natural insects. Only ecological chickens have enough natural feed and nutrition to produce high-quality products with high nutritional value and nourishing properties.
