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.

The country's total cotton output continued to be reduced by 5.605 million tons in 2015.
According to the national cotton production data released by the National Bureau of Statistics, the country's total cotton output in 2015 was 5.605 million tons, a decrease of 574000 tons or 9.3 percent compared with 2014. The decrease in cotton production is mainly due to the decrease in area. In 2015, the cotton sown area in China was 3799.0 thousand hectares (5698).

Land increase and decrease linked to inter-county transfer
Recently, Guangdong, Zhejiang, Anhui and other provinces have begun to brew policy innovation for inter-county transfer of linked indicators, and some provinces have begun to deploy pilot projects to explore first. It is reported that the Ministry of Land and Resources has begun to appropriately expand the pilot project of linking increase and decrease on the basis of the county.

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 ℃.

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.

Chinese Academy of Sciences: grain output in 2016 is likely to be reduced.
The forecasting Center of the Chinese Academy of Sciences released China's economic forecast for 2016 in Beijing. The Chinese Academy of Sciences estimates that the sown area of grain in 2016 will be about 112.1 million hectares, a decrease of 1.2 million hectares, or about 18 million mu, compared with 2015. If you do not encounter serious natural disasters, in moderate weather or

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. Heat stress on meat

Accumulation of macadamia nut oil
Macadamia nuts take about 215 days from fruiting to ripening, and when they mature 30 weeks after flowering, the kernel oil content of macadamia nuts is 75% Mel 79%. With the development of the fruit, the oil content of the kernel increases, while the total nitrogen (crude protein content) decreases, and the total sugar in the flower.

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.
