Matters needing attention in heatstroke prevention and cooling of beef cattle breeding in high temperature weather

When raising cattle in hot weather, it is necessary to do a good job of heatstroke prevention and cooling in the cowshed, adjust the management of raising cattle according to the actual situation, strengthen the sanitation and disinfection of the cowshed, and effectively avoid the occurrence of diseases.

Because in hot summer, beef cattle are prone to loss of appetite, heat stress and disease outbreak, so it is necessary to strengthen the feeding management of beef cattle in high temperature weather.

First, heatstroke prevention and cooling

1, strengthen ventilation.

You can open all the doors, windows and ventilation holes in the barn, install fans in the barn, turn on the fans to cool the barn from noon 10 to 5 pm every day, or install blowers at both ends of the barn to strengthen ventilation and cooling.

2. Sprinkle water to cool down.

First, you can sprinkle water on fences and sports grounds every two hours between 1 1 and 4 pm; Second, spray cooling facilities can be installed on the roof of the fenced house.

Water cooling must be combined with ventilation to achieve the desired effect, otherwise it will cause high temperature and high humidity, which is counterproductive.

Don't throw cold water on the cow directly. Due to intense cold stimulation, the sweat pores of cattle shrink sharply, the heat emission in the body is blocked, and the body temperature rises suddenly, which may lead to high fever and lung inflammation, and even lead to the death of cattle.

3. Do a good job in the renovation of the fence.

1. The roof, wall and ground of the cowshed shall be made of materials with good thermal insulation performance, such as wood shavings or foam under roof tiles, the wall shall be made of hollow bricks, and the ground of the cowshed shall be made of thermal insulation cement or rain leakage ground; The second is to increase the green area of the site and improve the environment in the site, and it is best to plant trees in the enclosure and sports ground; The third is to avoid direct sunlight, and pull a sunshade net on the roof of the beef barn to shade the sun.

Second, rationally adjust the breeding mode.

1, reasonable distribution of diet, appropriate supplementation of minerals and vitamins.

In hot summer, the ratio of protein to energy feed should be appropriately increased, and the intake of crude fiber feed should be reduced. At the same time, attractants can be added, and high-quality fresh raw materials can be selected to improve the feed intake and maintain the high growth rate of beef cattle.

2, stagger the high temperature, feed many times, and drink water frequently.

Adding 0. 1%-0.2% artificial salt, multivitamins or 0.5% baking soda to drinking water can adjust the electrolyte balance in beef cattle and reduce the occurrence of heat stress.

3. Reduce the feeding density.

The reduction ratio is 1/4- 1/3, which can avoid crowding, improve air quality and reduce heat stress, especially for pregnant cows. If the density is too high, it will lead to abortion due to hot and irritable fights, so it is best to raise it separately.

4. Control the breeding time.

Appropriately avoid the hottest July-August breeding and calving, and arrange production reasonably; At the same time, breeding and sperm collection should be carried out in the morning and evening when the weather is cool.

5. Reasonably arrange the transfer, sale, castration and inoculation time of cattle.

This work should be carried out in the morning and evening when the weather is cool to avoid long-distance transportation of cattle in high temperature season.

Third, do a good job in sanitation and disinfection of pens to prevent diseases.

1. Clean the feces at least 2-3 times a day, and disinfect it every 7 7- 10/time, so as to create a dry, clean and hygienic environment for beef cattle as much as possible.

2. Remove garbage, feces, etc. It is easy to breed mosquitoes in beef cattle pens and kill mosquitoes to block the spread of infectious diseases through mosquitoes.

3, do a good job of disinfection of beef cattle pens, cut off the source of infection.

Take different disinfection measures such as ultraviolet irradiation, spraying and drinking water according to the situation.

4. Strengthen the management of beef cattle feed and drinking water to prevent feed from rotting and drinking water pollution.

The strict import and export plan of feed shortens the inventory time and accelerates the turnover.

Do a good job in the storage and storage of silage corn, and follow the principles of timely harvest, early cellar entry, cutting and compaction, and good sealing.

5, according to the local immunization plan, timely vaccination, in order to establish a high level of immune groups, effectively prevent the outbreak of infectious diseases.
