High temperatures and high humidity: be on guard against Haemophilus parasuis disease
As temperatures rise and humidity increases, the incidence of bacterial diseases in pig herds will rise, and there is all the more need to be on guard against Haemophilus parasuis infection. Haemophilus parasuis infects only pigs and can affect young pigs from 2 weeks to 4 months of age, mainly causing disease around weaning and during the nursery stage, usually seen in pigs of 5 to 8 weeks of age, with an incidence rate of 10% to 15%, and in severe cases the mortality rate can reach 50%. Acute cases often first occur in pigs in good body condition. Affected pigs have fever (40.5 to 42°C), depression, reduced appetite, difficulty breathing, abdominal breathing

New edible mushroom variety: high-temperature mushroom Xiagu 93
The high-temperature mushroom "Xiagu 93" is the first high-temperature-type four-spore mushroom variety suitable for summer cultivation in China, bred in 1993 by researchers at the Horticulture Institute of the Zhejiang Academy of Agricultural Sciences through research efforts, originally named "Zhe AGh-1". This variety fills the gap in summer mushroom cultivation varieties in China. The fruiting period of the high-temperature mushroom coincides with the off-season for various edible mushrooms, when fresh mushroom supply is interrupted, and prices are 3 to 5 times higher than in peak season. It has been promoted in more than 20 provinces and cities including Zhejiang, Jiangsu, Shanghai, Fujian, Guangdong, and **. This variety passed variety certification in April 2000.

Sudden Temperature Changes: Farmers Should Guard Against Swine Influenza
Swine influenza is an acute, highly contagious disease caused by the swine influenza A virus. It is mainly characterized by sudden onset in pigs, rapid spread, high morbidity, low mortality, high fever, and inflammation of the upper respiratory tract. Epidemiological features: 1. It has obvious seasonality, occurring mostly in autumn and winter and in spring when temperatures change abruptly, and pigs are especially prone to the disease when it is damp and rainy. 2. Pigs of all ages, sexes, and breeds can be infected and become ill. 3. It often occurs as an endemic or pandemic. 4. It spreads rapidly, and within 2 to 3 days it

What is the most suitable temperature and humidity inside a snake enclosure?
Snakes are ectothermic animals, and changes in temperature greatly affect their growth and activity. Therefore, controlling the temperature and humidity inside a snake enclosure within the range suitable for snake growth and activity is another key issue in artificial snake farming. Generally, a temperature of 20-30°C is most suitable for the growth and reproduction of snakes. If it falls below 10-13°C, snakes curl up and become inactive; if in an environment above 40°C or below 0°C, weak and thin snakes will die in large numbers. So, in the process of artificially raising snakes, special attention must be paid to the outside

Three key aspects to focus on when cultivating mushrooms in high-temperature seasons
To cultivate mushrooms well in high-temperature seasons, three technical aspects need to be mastered. 1. Select suitable high-temperature-type mushroom strains. Currently, the more heat-tolerant mushroom strains include Xincheng 96, Sumo No. 1, and others. Among them, Xincheng 96 has a mycelium growth temperature of 18—36°C, with the optimum mycelium growth temperature of 25—33°C. Its fruiting temperature is 20-36°C, with the optimum fruiting temperature of 24—33°C, making it the most heat-tolerant strain currently available. The greatest advantage of this strain is that mushrooms do not discolor 2—3

Xiagu 93 is a high-temperature mushroom variety.
Through research, researchers in our laboratory successfully bred in 1993 the high-temperature-type four-spore mushroom "Xiagu 93" (formerly named "Zhe AgH-1") suitable for summer cultivation, filling the gap in China's summer mushroom cultivation varieties. This enables mushrooms in China to be grown for more than two seasons a year. The fruiting period of high-temperature mushrooms coincides with the off-season for various edible fungi, when the supply of fresh mushrooms is interrupted, and the price is 3 to 5 times higher than in peak season. It has already been promoted in more than 20 provinces and cities including Zhejiang, Sichuan, Jiangsu, Shanghai, Fujian, Guangdong, Hunan, and **, and local governments and mushroom

Promotion and Application of the High-Temperature Mushroom "Summer Mushroom 93"
Key Research Achievement Promotion Project of the Zhejiang Academy of Agricultural Sciences -- Promotion of the High-Temperature Mushroom "Summer Mushroom 93". This project was undertaken by the Horticulture Research Institute of the Zhejiang Academy of Agricultural Sciences. During the promotion process: 1. Strengthen promotion and publicity efforts: by participating in national conferences, various magazines, journals and news media, the variety characteristics and cultivation techniques of the high-temperature mushroom were publicized and introduced in multiple forms, and the promotion network of the "Zhejiang Province High-Temperature Mushroom Promotion Collaborative Group" was fully utilized, expanding the influence of the high-temperature mushroom; 2. Provide high-quality mother spawn and high-yield cultivation techniques:

Breeding and Promotion of the High-Temperature Mushroom 'Xiagu 93'
In December 2002, the provincial key science and technology project "Breeding and Promotion of the High-Temperature Mushroom 'Xiagu 93'", led by the Institute of Horticulture of the Zhejiang Academy of Agricultural Sciences, passed the achievement appraisal organized by the Provincial Department of Science and Technology. Summer is the off-season for the cultivation and production of various edible fungi in China, and the supply of fresh mushrooms on the market is interrupted. Therefore, carrying out the breeding of high-temperature mushrooms and establishing a complete set of supporting comprehensive cultivation techniques so that mushrooms can be grown for more than two seasons a year in China is of great significance for enriching China's mushroom varieties, improving mushroom quality, and meeting market demand for mushrooms. Through more than ten years of

Key Cultivation Techniques for the High-Temperature Mushroom Xiaogu 93
Xiaogu 93 is a high-temperature-type mushroom variety bred by the Zhejiang Academy of Agricultural Sciences. The cultivation techniques are as follows: 1. Cultivation season and facilities The cultivation season is from late March to October in the south, from May to September in the Yangtze River basin, and from June to August in the north. Mushroom house disinfection Existing conventional mushroom cultivation equipment such as mushroom houses or plastic greenhouses can be used for cultivation during the idle summer period, as well as plastic medium tunnel cultivation. Generally, immediately after the spring mushroom crop is finished, the waste material should be removed, the mushroom house and bed frames should be cleaned and disinfected, and before cultivation, dichlorvos
