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. Japanese, American, British and other Chinese studies

Clinical manifestations, prevention and treatment of heat stress in chickens
(1) the tolerance of chickens to heat. Because chickens have physiological characteristics such as high body temperature, exuberant metabolism and no sweat glands, the ability to tolerate high temperature environment is low, so high temperature has become the most harmful stress factor in chicken stressors. According to relevant measurements, the best digestion temperature for laying hens raised in China is 21-24 ℃, the best laying temperature is 15-20 ℃, and the relative humidity is 60% Mel 65%. When the egg production is above 28 ℃, the egg production decreases, and 1 ℃ per liter, the heat dissipation decreases, and the feed intake decreases by 1.6%, and 3% at about 30 ℃.

Analysis on the relationship between gecko activity and temperature
Gekko gecko is a temperature-changing animal, and its body temperature changes with the change of ambient temperature. When the ambient temperature is suitable, the gecko has a strong appetite, an increase in food intake and a faster growth rate; when the temperature decreases, the gecko's body temperature decreases, the activity decreases, the appetite decreases, the appetite is small or not, and the growth rate is fast.

Heat stress and its mitigation measures in summer and autumn chickens
Effect of heat stress on broilers 1. Physiological and biochemical changes of broilers under heat stress. When the ambient temperature rises, the chicken body temperature will rise with the ambient temperature rise, at this time the heart rate will accelerate, blood pressure will decrease, breathing will accelerate wheezing, and respiratory intoxication will occur in severe cases. In addition, heat stress can also lead to endocrine disorder, adrenocorticosteroid concentration increased significantly in the early stage of heat stress, but gradually decreased thyroid hormone secretion, activity decreased resulting in reduced metabolic rate. 2.
