How to cool down broilers in summer and how to prevent heat stroke in broilers in summer

1. Adopt the method of excessive ventilation.

The premise of excessive ventilation is that the temperature of the house is not higher than 32 degrees.

As we all know, in the case of excessive ventilation, the body temperature of chickens will drop by 3 to 5 degrees, when the temperature of the chicken house is not higher than 32 degrees, the body temperature of chickens is lower than 29 degrees, as long as there is no ventilation dead end, chickens will not suffer from heat stroke.

The principle of excessive ventilation: all the vents in the front section of the chicken coop are all opened, and the number of fans opened is based on the wind speed of the chicken coop reaching more than 4 meters per second.

2. Use fog lines and coop sprinkling.

In addition to the air cooling effect, which causes the temperature to drop, the evaporation of water can also bring about the water cooling effect.

If the temperature of the chicken coop has not reached the level of having to open the wet curtain, the fog line and the chicken coop sprinkling water cooling is also a good choice, air cooling with water cooling, can also provide a comfortable environment for the chickens.

When using the water cooling effect to cool down, pay attention to excessive ventilation to prevent and control the poor discharge of water vapor, resulting in a high temperature and high humidity environment, causing harm to the chickens.

3. Use a water curtain to cool down.

The use of water curtain is the most commonly used way to cool down in summer, and the water curtain can cool down quickly, but it has great drawbacks.

Nowadays, the construction of chicken coops is varied, and the installation of water curtains is also strange, and the lack of scientific expertise leads to the improper installation of most of the chicken coop water curtains.

Therefore, there is no problem with chickens without water curtains, but chickens will catch colds as soon as they use water curtains, and they will catch colds repeatedly, and even cause the occurrence of air sac inflammation.

When we use the water curtain, we must learn to let the cold wind go according to the route we want, which requires us to cross the sea and show our powers.

4. Provide chickens with plenty of cool drinking water.

Chickens need to use a lot of cool drinking water to cool down in a hot environment, be sure to provide chickens with enough cool drinking water, feeding medicine must avoid high temperature periods, to prevent heat stroke caused by poor palatability.

Five-day hot period to control feeding.

Most of the body's calories are in the feed supply, we can control the feed during the hot period, reduce the amount of feed and activity, provide a quiet and shady environment for the chickens, and help them survive every hot day.

Let them rest during the day and eat at night.

6. Add medicines to the water to relieve heat and cool down.

You can add anti-heat and cooling drugs to the water to help the body cool down.

Heat-relieving medicines contain borneol, peppermint ice and VC, which can help the body relieve heat stress.

Welcome to the exchange.

How to cool down broilers in summer, how to prevent heat stroke in summer of broilers, you can install a water curtain cooling system, cooling water curtain and negative pressure fan are used together, negative pressure fan makes the indoor air pressure lower, and the outside air enters through the cooling water curtain to achieve ventilation and cooling effect, small investment, good cooling effect, low operating cost, can effectively reduce the probability of animal disease, very popular with farmers.

Good cooling measures for broiler houses can provide a comfortable growth environment for broilers, increase feed intake of broilers, improve feed remuneration, and accelerate the growth of broilers; It can also enhance the resistance of broilers, reduce the occurrence of diseases, and reduce breeding losses.

Broiler breeding is an economic behavior, must be in pursuit of maximum economic benefits for the purpose, therefore, broiler house cooling to "applicable, convenient, economical" principle, make full use of "wind", "light", "electricity", "water" resources, the use of different technical measures, to achieve the expected cooling goals.

1. Ventilation and cooling. Close the doors and windows of the chicken house before the temperature rises in the morning, and open all doors and windows after the temperature drops in the evening to allow air exchange between the inside and outside of the chicken house and improve the air quality in the house.

2. Shading and cooling. When building a chicken coop, two rows of poplars are planted on both sides of each chicken coop, the tree is about a meter away from the chicken coop, the row spacing is 3 meters, after the poplar tree becomes a forest, the luxuriant poplar tree shades the sunlight that irradiates the chicken coop, can reduce the temperature of the chicken coop 3 8, and can also improve the small environment around the chicken coop. Second, you can plant creepers, loofahs and other plants, so that these plants climb all over the roof, so that "plants" protect "animals", establish an environment for animals and plants to "coexist in harmony", and generally reduce the temperature of the chicken coop 2 3.

Third, the sunshade net can be used to shade the sun, the sunshade net must be higher than the roof of the chicken coop more than 50cm, with bamboo, wooden pole support to fix the sunshade net, to prevent wind blowing, rain damage to the sunshade net and noise, affecting the growth of broilers.

3. Water curtain cooling. Set up a Yueneng water curtain at the air inlet to make the outside hot air enter the chicken coop after cooling; The lower end of the water curtain must not be lower than the height of the chicken bed, and the width can be narrower than the width of the chicken coop. The other end of the house is equipped with an exhaust fan that, when using a water curtain, can be opened before the temperature rises and closed in the afternoon when it cools down.

In this way, the temperature can be reduced by 3 6.

Yueneng fan water curtain chicken coop cooling.

Broiler farmers can minimize investment and reduce costs according to the age of broilers, feeding density and chicken house construction environment, as well as existing conditions, and adopt one or several cooling measures to achieve cooling effect.

Cooling method of summer chicken coop for breeding broilers:

1. Ventilation and cooling method, install an industrial exhaust fan on the wall of the chicken coop to pump out the hot and stuffy air outside and let the indoor air flow.

2. Water-cooled cooling method: Install cooling wet curtains or environmental protection air conditioners on the windows or walls, and send water-cooled air to the room to cool down.

It is recommended to find a professional to give specific suggestions for the plan and the selection of equipment according to the actual use.

1. Reduce the feeding density and reduce the amount of broilers per unit area. It is recommended to have 8 chickens per square meter for standardized coops and 6 chickens per square meter for loose sheds. 2. Increase the air volume, increase the wind speed, and ensure good ventilation.

The current standardized chicken coop adopts longitudinal ventilation in summer, which requires the small air inlets on both sides to be closed and the large air inlets to be opened, so that the chicken coop can reach a certain wind speed. When the wind speed reaches 2 meters per second, the perceived temperature of the broiler can be reduced by 6. When the wind speed reaches meters per second, the body temperature of the broiler should be reduced by 8.

For simple sheds, small fans can be installed for ventilation. 3. Inject anti-heat stress drugs to enhance anti-stress ability. Add VC to the feed, add 100-150 grams to 500 kg of feed; Add baking soda to drinking water in a ratio of 1.

At the same time, reduce the drinking water temperature, drink deep well water (deep well water temperature 8-10), change water frequently, and ensure sufficient drinking water. 4. In the summer of high temperature and high humidity weather, for the broilers raised on the ground, the bedding should be changed frequently to reduce the environmental humidity to alleviate the adverse effects of heat stress.

Because laying eggs is an energy-intensive, heat-producing process. The chicken shed should be made larger, and installed in a ventilated and sunny place, not cut off the water, and can be fed with some hot water.

If the chicken shed is small, you can consider installing a few air coolers, also called environmental protection air conditioning, which has low requirements for airtightness to cool the chicken shed, and the energy consumption is also small, and the effect is still good.

Yue Neng air cooler.

Cool down and ventilate, clean up feces. Reduce the density of chickens in the pen.

It is recommended to put a fan or something to cool down.

<> the hot weather in summer, the general feeding density in the chicken coop is relatively large, and the chickens are more sensitive to temperature, so it is necessary to pay attention to heatstroke prevention and cooling in the hot summer, and prevent epidemics. Let's talk about how to cool down chicken farms in summer and what are the precautions for raising chickens in summer. Please attach great importance to the following six items:

Closed chicken coop can be installed with fans or ceiling fans, longitudinal ventilation is better than horizontal ventilation, and the wind speed in the chicken coop in summer is suitable for meters and seconds.

Wet curtain excavation is the most economical and effective cooling measure for large-scale production, and longitudinal ventilation combined with wet curtain cooling has a better effect on preventing heat stress. An open coop can be fitted with a fan and all windows and doors open to promote air circulation.

Chickens have no sweat glands, and the heat generated in the body can only be lost by breathing, and the adaptability to high temperatures is very poor, so the chicken coop needs to maintain a cooling time of 6-8 hours a day.

When the house temperature exceeds 30, you can use a high and low fog volume rotary nozzle sprayer to spray cool water directly on the roof or chicken body, spraying once every 2-3 hours, which can reduce the temperature of the chicken house by 6-8.

Generally, the area required to cage a chicken is square meters, and each cage is 3. Flat free-range, 3 to 5 per square meter. Large flocks are reared, each flock is 200 300 animals is preferable, and the flock is separated by a fence to facilitate internal and external air circulation.

The suitable density of chickens at different feeding stages: 30-25 chickens per square meter at the age of 7-14 days; 21-28 days old, 25-15; 35 days old to 10-5 slaughter.

Chicken manure is very easy to ferment in summer, inducing respiratory diseases. Therefore, the manure and bedding in the chicken house should be cleaned in time (at least once every other day).

The weeds around the chicken coop should also be removed, the sewage ditch should be filled, the chicken coop should be nailed with screens, and the mosquitoes and flies should be sprayed regularly to ensure that the broilers have a peaceful environment.

In the high temperature season, the light should be turned on early and turned off early, that is, the light should be turned on at 3 o'clock in the morning and 4 o'clock in the morning, and the light should be turned off at 7 o'clock and 8 o'clock in the evening, and the number of feeding or homogenization should be increased before the temperature rises in the morning, so that the chickens can have a cool time in the day to eat.

At the same time, try to minimize the activities of the chickens, and stop feeding at 1 pm and 3 pm on the hot day of the day to reduce the feeding activities of the chickens.

Provide fresh, clean and cool water throughout the day The drinking water of laying hens in high temperature weather is about 3 times 4 times the feed intake, to ensure that the chickens can drink clean and pollution-free cold water all day long (the water temperature is about 10). Dog days, ** good to change the water every 2 hours.

In summer, we should focus on the prevention of chicken coccidiosis, and we should also pay attention to the drug prevention and control of colibacillosis and white coronavirus, and do a good job in immunization.

As long as the breeding and management conditions of laying hens are artificially improved, and a suitable environment is created, the laying hens can continue to lay more eggs.

1. Greening and cooling: planting vines such as creepers around the chicken coop and letting them climb on the walls and roofs of the chicken coop can not only block the strong sunlight, but also reduce the indoor temperature due to the air flow between the leaves and the wall.

2. Spray cooling: Spray cooling has obvious effect on spray cooling in the chicken house, but it is easy to increase humidity, and it is not suitable for use in places with high temperature and high humidity.

3. Fan cooling: install a certain number of fans at a certain distance in the chicken house, and turn on the fan when the temperature in the house rises, but the noise is loud, but it will cause chicken stress.

4. Water curtain cooling: water curtain cooling is the use of fan negative pressure system and water curtain to artificially reproduce the physical process of water evaporation and cooling in nature, which can make the air in the chicken house fresh and the temperature suitable. However, chicken coops with water curtains for cooling are more expensive.

5. Thermal insulation layer cooling: enhance the thermal insulation ability of the roof and wall to reduce the solar radiation heat entering the house; Set up a shade net or awning outside the window to prevent direct sunlight from shining on the flocks.

6. Improve the internal and external environment of the chicken coop and cool down: insist on removing feces every day in the house to reduce the heat production of feces in the house; improve ventilation conditions and increase the area of vents and roof skylights; Doing a good job in the greening of the environment around the chicken coop can not only reduce radiant heat, but also absorb carbon dioxide, reduce dust density, and purify the air inside and outside the house.

7. Drug cooling: Vitamin C is the best medicine for heatstroke prevention and cooling, and it is recommended to double the dosage in summer.
