Heat stress and its control in pigs in summer
Heat stress refers to the sum of non-specific physiological responses of the body to any requirements put forward by the thermal environment in an extremely high ambient temperature. With the rapid development of intensive and high-density feeding, most southern regions are becoming more and more urgent to alleviate the environmental pressure caused by high temperature in summer on the pig industry, and the climate in the north also has an increasing trend. In recent years, the highest temperature in Beijing has also reached more than 40 degrees. The decline of pig productivity caused by heat stress has attracted more and more attention of livestock environment and feed nutrition researchers.

Beware of heat stress in pigs in July
In July, Anhui Province entered a hot and scorching heat, which issued a heat warning to the pig industry and the breeding industry. With the large-scale intensification of the pig industry, the density of pigs increases, and the breeds of pigs are mainly outside the three, pigs are more prone to heat stress. How to control the summer heat stress of pigs has become one of the important tasks of pig farmers. Heat stress is an invisible killer compared to the epidemic disease, the damage of heat stress to pig farms is often invisible. The most suitable temperature range for fattening pigs is 18 ℃ 21 min, 32-

After the ambush, it is hot for people to prevent summer heat and rice to prevent heat and cool down.
High temperature heat injury is one of the common diseases of rice. High temperature heat damage of rice occurs in some areas every year, and causes serious economic losses. For example, in 2006, high temperature damage to rice occurred in many areas of Anhui Province, resulting in 2 million mu of rice affected. ...

Is rice resistant to high temperature? How to deal with the heat damage caused by high temperature? What's the impact?
The damage of high temperature to rice plant is closely related to the growth period of rice. Many studies have shown that during flowering, high temperature and heat injury will affect pollen maturation, anther cracking, pollen germination in stigma and pollen tube elongation, resulting in non-fertilization pairs.

Technical measures for Prevention and Control of High temperature Heat damage of Rice
Rice high temperature heat damage generally refers to an agrometeorological disaster in which the air temperature exceeds the upper limit of the normal growth temperature of rice during the heading and fruiting stage, which affects the normal flowering and fruiting, resulting in an increase in the percentage of empty grains and a decrease in yield or even no harvest. Xuzhou collates the high temperature heat damage of rice for everyone.

Adjustment of feed formula by damp-heat measures for pigs
1. Adjust the feed formula to increase the feed intake of pigs. 1. Under the condition of high temperature, in order to reduce body heat gain and heat dissipation burden, it is bound to reduce feed intake, resulting in insufficient intake of nutrients such as energy and protein in pigs, and make necessary adjustments to the feed formula. it has become one of the effective measures to overcome heat stress. The more the body heat of nutrients increases in ①, the more serious the heat stress after feeding. Fat has the advantages of small volume, high net energy value and less body heating. it is an ideal energy source for pigs under high temperature, and can be added less than 5% to feed.

Heat stroke in chickens and ducks and its prevention and control measures
1. Causes of chicken heatstroke: continuous high temperature, low shelf lifting of chicken house, poor heat prevention and cooling facilities, lack of ventilation, causing obstacles to heat accumulation in the house, so that the temperature in the house is high; feeding density is too high, chickens release more heat, which increases the temperature of the house; untimely removal of feces, accumulation of chicken manure increases the concentration of ammonia and humidity in the house, and the heat dissipation of chickens is hindered under the condition of high temperature and high humidity. The energy in the feed is on the high side, which causes the chicken to be too fat and accumulate too much fat. two。 Symptoms and pathological changes of heat stroke in chickens: first of all

Heat stress symptoms of pigs
Pig heat stress refers to the sum of non-specific physiological responses of animals in high temperature environment to thermal environment. In the process of raising pigs should be carefully observed, if there are symptoms of pig heat stress should be timely treatment. So what are the symptoms of heat stress in pigs?

How to deal with sow heat stress in summer? What kind of injection should I get?
Pigs are thermostatic animals with thick subcutaneous fat, underdeveloped sweat glands and slow heat dissipation, so pigs are not heat-resistant. Heat stress in summer is easy to affect the fecundity of sows, so how to deal with it? What kind of injection should I give if there is heat stress? There's only one.

Effects of different temperatures on Pigs and its Countermeasures
First, the effect of environmental temperature on pigs. 1. The effect on the health of pigs. In the environment of continuous high temperature, the resistance of pigs decreased significantly, the body heat balance was destroyed, the body temperature increased, coma, heat radiation disease occurred, and died in severe cases. In a low temperature environment, pigs contract peripheral blood vessels in order to keep warm, causing local frostbite. Low temperature can cause respiratory diseases, but also often cause rheumatism, arthritis and other diseases. Low temperature has a greater impact on piglets. According to statistics, half of the piglets who died were frozen to death or died of cold-related diseases.

Do a good job of preventing heat and cooling chickens in summer
The most suitable temperature for laying hens is 17 ℃ ~ 28 ℃, and the temperature that has little effect on production is about 7 ℃ ~ 27 ℃. When the summer temperature in Shandong Province is more than 35 ℃, chickens will faint and die when they reach 40 ℃. The experiment proved that when the temperature in the henhouse reached more than 30 ℃, the sperm of the rooster decreased, the sexual maturity of the hen was delayed, the fertilization rate decreased by 60%, and the laying rate of laying hens decreased generally. At the same time, due to the decrease of blood calcium and the imbalance of acid-base balance, it was easy to induce other diseases, such as Escherichia coli, mycosis and so on. Broilers are easy to fat because of their large size.
