What disease does chicken get easily in summer? How to cool chickens in summer?

The weather is hot in summer. Under the hot, humid and sultry climate conditions, diseases such as heatstroke, coccidiosis, aflatoxin poisoning, chicken cholera, Newcastle disease and chickenpox are most likely to occur. Pay attention to take corresponding measures to deal with it, starting from daily management. When raising chickens in summer, the cooling measures can be taken as follows: strengthening ventilation, spraying to cool down, shielding heat sources (building a sunshade or hanging a translucent black curtain, painting the sun wall and roof with white paint, etc.). ), replenish water, reduce feeding density and strengthen management.

First, what disease is it easy to get when raising chickens in summer?

1, heatstroke

The weather is hot in summer, and there is often a sultry and humid phenomenon. When the temperature in the henhouse is too high, chickens are prone to heatstroke. Heatstroke chickens will feel thirsty and drink more water, which will cause diarrhea, depression, dyspnea and hunger strike. If it is serious, a large number of chickens will die. To prevent chicken heatstroke, it is necessary to open the window for ventilation every day, install fans or cooling equipment to reduce the ambient temperature. If the chickens are found to have heatstroke, they need to be moved to a cool place, and needles should be inserted at the comb and chicken wings to bleed.

2. Coccidiosis

Sick chickens show symptoms such as listlessness, emaciation, anemia and bloody dysentery. Chickens aged 10-50 days are susceptible to this disease. When breeding, vitamin A and vitamin K should be added to the feed to meet its growth needs, and the feed, drinking water and environment should be clean and hygienic. The feces should be cleaned once a day, and quicklime should be sprayed once a week for disinfection.

3, aflatoxin poisoning

Feed is easy to mildew in summer, and feeding moldy feed often causes aflatoxin poisoning, leading to chicken waste food, diarrhea, pale or jaundice skin, decreased productivity, failure and death. Therefore, we should pay special attention not to feed moldy and deteriorated feed, and keep the feed well, and pay attention to moistureproof, ventilation, rat prevention and so on. Once moldy feed is found, it should be replaced in time.

4. Cholera in poultry

Chicken cholera is most prevalent in hot, humid and sultry climate in summer. Sick chickens are characterized by listlessness, loose feathers, dark red comb, difficulty breathing, high body temperature of 43℃-44℃, and grayish yellow or green feces. Chicken cholera is mainly prevention. Chickens over 3 months old are vaccinated with aluminum hydroxide vaccine or attenuated vaccine of avian cholera. After 7 days, they become immune, and the immune period can reach 6 months.

5. Xincheng disease

In the early stage of Newcastle disease infection, chickens will be depressed, their feathers will be loose and shiny, and their cockscomb will be dark red or purple-black. Goo goo? Crying, mouth breathing, thin and sticky feces (sometimes with blood), the mortality rate is extremely high. This requires comprehensive prevention and control to improve the disease resistance and immune response of chickens. Strict disinfection, isolation of seriously ill chickens, cut off the route of transmission. Vaccination is a very good method.

6, chickenpox

There are many mosquitoes in summer, and it is easy to get chicken pox. For chickenpox disease, we should vaccinate chickenpox vaccine as soon as possible, and the vaccination method is under the wing. For the chickens at the early stage of the disease, it is necessary to isolate the sick chickens in time to prevent the healthy chickens from being infected, and to vaccinate the sick chickens urgently, and to carry out drug treatment after 12 hours. It is also necessary to strengthen the daily feeding management and do a good job in the sanitation and disinfection of chicken houses.

Second, how to cool chickens in summer

1, strengthen ventilation

Keeping the indoor temperature well ventilated can take away the indoor heat in time, reduce the content of harmful gases such as hydrogen sulfide and ammonia, and make the indoor air cool and fresh. Generally, wet curtain can be installed to cool down and longitudinal ventilation can be implemented; Or increase the number of fans to improve the indoor air flow speed; You can also install some tools such as fans and ceiling fans to achieve better ventilation effect.

2. Spray water (fog) to cool down

The top of the henhouse is equipped with a spraying device, which can be sprayed to cool down, and it is best to start the fan at the same time. If you use water spray to cool down, you should spray water directly on the roof, and it is best not to spray water on the chicken coop, because it will scare the chickens. If it is sprayed, it can be sprayed slightly in the direction of the chicken house.

3. Heat insulation source

On the one hand, you can set up a sunshade or hang a translucent black curtain on the window of the henhouse to isolate the heat source; On the other hand, the sunny wall and roof of the henhouse can be painted white with white paint to enhance reflection and reduce heat absorption; In addition, if possible, you can plant grass and trees around the chicken house to let the plants absorb heat and lower the temperature.

Step 4 replenish water

In summer, chickens must be provided with enough cool drinking water to ensure enough drinking places. The best drinking time for chickens is 6- 10 in the morning. Appropriate amount of anti-heat stress and anti-summer drugs can be added to drinking water. The temperature of chicken drinking water should be controlled at 8- 12℃ and kept below 25℃. Ice cubes can be added to the water, or deep well water can be used to lower the water temperature. Pay attention to burying the drinking water pipe in the ground and regularly check whether the drinking water nozzle is blocked.

5. Reduce the feeding density

Reduce the breeding density according to different breeds to ensure that chickens have enough space. Generally, when breeding, ensure that each chicken has an area of 0.4 square meters, so as not to affect their growth, especially in summer, and control the density reasonably to achieve the purpose of cooling down.

6. Strengthen management

It is hot in summer, so it is necessary to adjust the feeding time and frequency, arrange the feeding at the coolest time, and pay attention to uniform feeding. Attention should also be paid to maintaining the environmental sanitation in the house, and the feces in the chicken house should be removed every day to reduce the heat generation of the feces in the house. There are 1-2 times more chicken farms using dung scraper than usual.
