1. Temperature management

(1) The optimum temperature for adult flocks: between 18 and 23 degrees Celsius, high temperature is likely to cause heat stress.

(2) Look at the chicken temperature: pay attention to the humidity of the chicken house. Use the body temperature during the day, find ways to cool down, so that the flock can reach a comfortable body temperature; use the indicated temperature at night.

2. High temperature and heat stress

Heat stress index = relative humidity (RH%) + Fahrenheit temperature (OF) 160. 160 Reduced feed intake, increased drinking water, and decreased production performance. 165 Flocks begin to die, with severe damage to the lungs and cardiovascular system. 170 A large number of deaths. When the temperature exceeds 28 degrees Celsius, the mouth is gasping. The temperature exceeds 30 degrees Celsius, the mouth is gasping, the feeding is decreased, and the drinking water is increased. When the temperature exceeds 32 degrees Celsius, the chickens appear sputum, lack of oxygen, rapid increase in respiratory rate, snoring, strange screaming, and serious death.

3. Heat stress is the control measure:

Use cooling equipment: fan + wet curtain, first turn on the fan that can be used, and use the wind speed to achieve the appropriate somatosensory temperature to produce the air cooling effect.
Secondly, use wet curtains: the temperature is over 30 degrees Celsius, the humidity is lower than 75%; gradually use, the range is from small to large; first use the two sides of the wall, and finally use the gable wet curtain. Finally, the windshield is installed in the chicken house to reduce the cross-sectional area of the house and increase the wind speed.

4. Density is not grouped

The density of flocks in summer chicken cages should be reduced, and each group of 3 layers should be 24-25. The flocks should maintain a reasonable density and should be grouped as soon as possible. The first group should be 8-13 days old, and the second group should be 21-22 days old. Summer grouping should be in the morning or evening to reduce heat stress in the flock.

5. Feeding management

Feed feeding: adjust the feeding time and feed in a cooler time. In the morning or evening, avoid the high temperature period, do not concentrate on feeding before 6 pm; pay attention to the mildew and deterioration of the feed to prevent poisoning or intestinal diseases, daily net trough and light limit once.

6. Drinking water management

Fresh, clean drinking water is provided to ensure adequate water. Protect the health of the intestines. Water quality standard: Total bacterial count standard: less than 100 per ml; E. coli should be 0 per ml and no more than 50. The water line should be cleaned regularly.

During the feeding period, the height of the waterline is adjusted every two days according to the age of the flock, so that the chicken can be raised through the waterline. Check the water line nipple every day for water, and replace the water line or leaking water line nipples in time to avoid disease caused by lack of water in the chickens.

7. Chicken out of the bar management

When the outside temperature is higher than 26 degrees Celsius, the chickens will be slaughtered. After the chicken battery cages are loaded, the water should be cooled in time. When the water is pumped, it must be thoroughly penetrated. During the slaughtering of the slaughterhouse, it is necessary to timely water and cool down to prevent the heat of the chickens.

Creating a living environment that is conducive to rapid growth and healthy development is a basic requirement for the healthy growth of broilers. What should be the environmental control of broiler houses?

temperature control

Chicks lack thermoregulatory capacity and must provide a suitable temperature. The temperature is too high, the intake is reduced, the drinking water is increased, and the growth is slow; if the temperature is too low, it is easy to cause respiratory diseases, indigestion, increase feed consumption, and the piles may cause the chicken to die. When the temperature is suitable, the chicks are evenly distributed and the activities are normal.

Humidity control

Humidity is the water content in the air, and proper humidity is closely related to the normal development of the chicken. Humidity is high, the house is damp, the bacteria breeds fast, the chicken is prone to disease; the humidity is small, the house is dry and dusty, and the chicken is prone to respiratory diseases. During the brooding period (the first 3 weeks), the relative humidity is controlled at 65% to 70%. During this period, the air is easy to dry due to the high temperature, and it is necessary to prevent the chicks from dehydrating due to low humidity.

Ventilation control

Ventilation and ventilation is to properly exclude the dirty air, pathogenic microorganisms, dust and moisture in the house, reduce their influence on the growth and development of the chicken, and exchange the fresh air outside to promote the rapid growth of the chicken. Ventilation can be done by natural ventilation and mechanical ventilation.

Lighting control

Control lighting is mainly to control the lighting time and light intensity. There are two characteristics of broiler illumination: 1 The illumination time should be as long as possible, which is the need to prolong the feeding time of the chicken, adapt to rapid growth, and shorten the growth cycle. 2 The light intensity should be as weak as possible, in order to reduce the excitement and movement of the chicken and improve the feed efficiency.

Density control

The brooding density refers to the number of chicks fed per square meter of the chicken battery cages . Appropriate stocking density can ensure the normal growth and development of chicks. The breeding density is too large, the chicks are crowded and piled up, the growth is slow, the development is not neat, the environmental pollution is aggravated, the disease spreads quickly, and the mortality rate is high. The density is too small, which is not conducive to heat preservation, resulting in waste of feeding area, energy, labor and so on. The feeding density of broilers should be flexibly controlled according to the specific conditions of the structure, ventilation and feeding conditions of the house.

High temperature in summer is the biggest obstacle to raising chicken. Chickens do not have sweat glands, so they cannot evaporate their body's calories by evaporating sweat. Therefore, we should artificially cool the chickens. The following small series introduces you to several common farm cooling measures.

1. It is necessary to improve the internal and external environment of the chicken house and strengthen the function of cooling and heatstroke prevention.

Try to enhance the insulation capacity of the roof and walls, reduce the solar radiant heat entering the house; set up a sunshade net or awning outside the window to prevent the sun from directly illuminating the flock; keep the manure every day to reduce the feces in the house Heat; improve ventilation conditions, increase the area of vents and roof skylights; do a good job of environmental greening around the chicken house to reduce radiant heat, but also absorb carbon dioxide, reduce dust density, and purify the air inside and outside the house.

2. Take necessary heatstroke prevention measures.

Increasing the wind speed in the chicken house can take away the heat production of the chicken body. If the wind speed in the house can reach 1-1.5 meters per second, the heat stress of the chicken can be alleviated; after having a certain wind speed in the house, it can be sprayed in the house. Use water evaporation to reduce the temperature, but do not spray water in the chicken house at noon, and can not sprinkle water on the ground. High temperature and high humidity chickens are extremely easy to die. Conditional chicken farms can adopt longitudinal ventilation to install wet curtains. It can ensure the safety of the chickens in the summer; let the chicken drink the cool drinking water, the lower temperature drinking water can reduce the heat stress of the chicken, can use the cool groundwater, should put the water at the end of the water pipe in about 2 hours, Make the water temperature inside the water pipe low.

3. It is to use drugs to improve the ability of chickens to resist heat stress.

Vitamin C is the best medicine for heatstroke prevention and cooling. It is recommended to double the amount of summer use. The death rate is severely increased by vc. The sodium bicarbonate and vc can not be used at the same time. The effect can be reduced by using 0.2% of cheap baking soda. Mixing materials to alleviate a series of reactions caused by respiratory acidosis, but do not advocate too long-term use, so as to avoid the rise of intestinal pH, you can use some Chinese herbal medicine borneol and other compound preparations. In the treatment of heatstroke chickens, it is necessary to use vc and must add Zhengda or Pulsatilla powder or neomycin, colistin, lincomycin and other drugs effective against enteritis.
 
If you choose a reliable poultry equipment manufacturers, using fully automatic poultry farming equipment to raise chickens will help the chicken farms in summer to cool down and moisturize.

There are many windy weather in autumn and winter, what problems should be paid attention to by chicken farmers and how to do well? In the autumn and winter seasons, especially in winter, there are more windy weather. We all know that ventilation has a great impact on the success of raising chickens in winter. In many articles, chicken farmers have seen articles that should pay attention to ventilation in the winter, or how harmful gases will affect the health of the flock. Since it is all wind, the wind will definitely affect the ventilation of the house, and the impact is still great.

What is the danger of winter wind on the chicken house and poultry cage equipment?

The biggest hazard caused by windy weather in winter chicken houses is cold stress. Even people, in the cold winds of winter, can tremble with chills, let alone chickens that are easy to stress. If a strong wind blows, the chicken farmers are not well coped, the flocks are severely cold-stressed, and the respiratory tract is stimulated to cause various respiratory diseases. The immunity is reduced and various chicken diseases are easy to find. This is the core cause of the frequent outbreak of chicken disease after windy.

Chicken house measures to deal with windy diseases

Therefore, coping with the windy weather in autumn and winter is a technology that chicken farmers must master in winter. Fortunately, this is a matter of wind, there is a weather forecast that can be known in advance, and chicken farmers can prepare early. Knowing the fact that the wind is going to be strong next, the chicken farmers should be prepared according to the direction of their own chicken houses, the wind direction and the wind that will be blown, mainly to avoid letting the cold wind blow into the chicken when the windy weather arrives.

During the summer season, the weather is hot, which often causes the chickens to eat less, grow slowly, reduce egg production, and even cause chickens to die. Based on the experience of integrated poultry farming equipment manufacturers, talk about your own opinions on the management of chicken management in summer.
 
1. Change the ambient temperature.

The optimum egg laying temperature for laying hens is 13-25 degrees, while the summer temperatures generally exceed 25 degrees. Therefore, changing the ambient temperature and creating a good microclimate for laying hens is a top priority for chicken farmers in summer. The specific method is to do a good job of greening in the spring, planting trees and vines around the house to clear the weeds around the house; before the summer season, build a pergola on the sunny side of the house; The exterior wall is painted white! Brush it in white to reduce heat absorption by dissolving 0.50 kg of salt with 46 kg of water, adding 40 kg of lime, 4.2 kg of white cement, adding 68 kg of water, stirring evenly, painting or spraying the roof and External wall, this method can reduce the temperature in the house by 1.5-2 degrees. In addition, we must pay attention to strengthen the ventilation of the house, convective heat dissipation, conditional installation of the wet curtain, and vertical ventilation to cool down.

2. Disinfect the chicken spray.

In the case of continuous high temperature, especially in the field where the number of chickens is concentrated! "It is best to install spray equipment in the chicken house. Generally, the two water pipes are 6 meters apart, and a nozzle is installed every 3 meters on the water pipe. When the weather is hot at noon. Spray several times, can reduce the temperature of 3-5 degrees ' (Note: to choose a highly effective, non-irritating, low-odor disinfectant, so as not to induce chicken respiratory disease).
 
3. Reduce the stocking density.

Increase the number of drinking fountains and feeding area. In the summer, it is necessary to clean up the flocks in time and eliminate sick, disabled, weak chickens and fake hens to reduce the stocking density and feeding costs.

4. Shearing and cooling.

Chickens do not have sweat glands, and the way to lower their body temperature is to dissipate heat by speeding up breathing, opening the mouth and wings. Therefore, at night, the feathers of the neck, back, wings, chest and abdomen, inner thighs, etc., which affect heat dissipation, can be cut off. The principle of shearing is as follows: the depth of the shearing is not to damage the skin and the large capillary tube does not flow after cutting. The long tail of the chicken tail and the long feather of the chicken wing should not be cut, and the cut in the early summer is less, and the cut in the summer.
