Both sunstroke and heatstroke in pigs are caused by high temperatures
In the hot summer, pigs are prone to heatstroke. In fact, heatstroke is the collective term for sunstroke and heatstroke, which traditional Chinese veterinary medicine calls black-sweat wind. Causes The causes of sunstroke and heatstroke differ, but their pathological processes cannot be completely separated. Sunstroke occurs when pigs are exposed to direct sunlight for too long, causing a rise in physiological body temperature and overheating and warming of the skin, which dilates the skin blood vessels. On the other hand, overheating of the head leads to congestion of the brain and meninges, ultimately causing disorders of the cerebral cortex regulatory function and the vital centers in pigs.

A Detailed Guide to the Methods of Capturing and Taming Wild Hazel Grouse
The history of artificial breeding of wild hazel grouse is still less than 10 years, so capturing and taming are effective ways to solve the shortage of breeding stock. 1. The trapping time is best from September to November each year. They lay eggs in May and the chicks hatch in June; during this period the hazel grouse is in plump body condition, reaching its highest weight of the year. 2. Trapping methods: set up some homemade trapping tools in areas where hazel grouse are frequently active, such as snares, capture cages, etc. If conditions permit, you can make full use of the hazel grouse's flocking tendency by continuously imitating the hazel grouse's call to make the birds gather together, and then capture them with a net. 3

Indoor Cultivation Techniques for Oyster Mushrooms: A Detailed Guide to Mushroom House Setup
The mushroom house should face south, be built on high, dry ground with good drainage, close to a water source, and in a well-ventilated location; its size can be determined according to specific conditions. The design of the mushroom house must take into account the growth requirements of oyster mushrooms, favoring ventilation, moisture retention, and a certain amount of scattered light. The windows of the mushroom house should be installed on the walls at both ends of the aisle, one above and one below, with the upper window slightly lower than the eaves and the lower window 6-10 cm above the ground. The bed frames inside the mushroom house should be sturdy and neat, and convenient to work with. The bed surface is generally 0.6-1 m wide, and the bed frames generally have 4-5 tiers, with the bottom tier 0

Summary of Experimental Trials on Delayed Cultivation Techniques for Hongxue Peach in Plastic Greenhouses
Hongxue peach is an extremely late-maturing peach variety. When cultivated in the open field in our county, the fruit is difficult to ripen due to late-autumn rainfall and frost. Therefore, starting in 2001, we conducted delayed cultivation trials in plastic greenhouses using technical measures such as early promotion followed by later control, delayed flowering, bagging to protect against rain, and covering the greenhouse to regulate temperature, prevent frost, and protect leaves. The results showed that facility-grown Hongxue peach bore fruit in the second year after planting, entered full production in the third year, could delay fruit ripening by about 20 days, and markedly improved fruit maturity and the rate of high-quality fruit.

How to control onion maggots in garlic? You can use 48% Lorsban
Reader Yuan Yong from Group 2, Jixing Village, Tongshang Town, Dafeng City, Jiangsu Province, wrote in to say that in 2005, onion maggots broke out severely in local garlic fields. Digging up 1 garlic plant revealed 6 to 8 maggots in the root and stem, causing some fields to suffer almost total crop loss. Many garlic farmers were extremely anxious and hoped we could ask experts to provide a solution. On this issue, we consulted relevant experts at the Plant Protection Station of the Jiangsu Provincial Department of Agriculture and Forestry. The experts said that the onion fly, also called onion maggot or garlic maggot, belongs to the order Diptera, family Anthomyiidae, and is a common pest on Welsh onions. In mild cases, it reduces yield by 10% to 20%; in severe cases, by more than 30%,

Main Causes of Non-Disease Death in Koi and How to Solve Them
I. Water Quality Problems Currently, household koi keeping mainly uses tap water. In some areas, the source water for tap water is of poor quality, and water plants use large amounts of disinfectants and cleaning agents during treatment. After a water change, the fish cannot adapt and become poisoned, which is why water treatment steps such as sunning and aerating the water before a change are necessary. Chlorine in the water is the main cause of fish poisoning. During water changes, a gradual step-by-step method should be used as much as possible, completing the change in several stages, and an appropriate amount of sodium thiosulfate should be added to remove residual chlorine from the water.

Why do pigs grind their teeth? The main causes are these
1. Single feed and malnutrition. It is best to feed pigs compound feed. When feeding concentrated feed, it should be paired with green and coarse feed, and minerals and trace elements should be added in appropriate amounts. For example, adding 1%-2% mineral feed to the pig's diet, such as bone meal, calcium hydrogen phosphate, eggshell powder, etc., and adding 0.25%-0.5% salt, etc., has a certain effect on preventing pigs from grinding their teeth. 2. Chronic indigestion in pigs. For pigs with indigestion, the stomach should be strengthened and appetite stimulated. For pigs weighing more than 10 kg, use 0.3 g

Detailed Explanation of Key Technical Points for Greenhouse Tea Plant Cultivation and Management
Covering tea gardens with plastic greenhouses is an important cultivation and management technique for advancing the harvest time of famous premium tea, improving quality, and significantly increasing economic benefits. The main function of the greenhouse is to preserve heat and prevent frost and freezing damage. Generally, the film is erected and covered from late October to late December of the previous year before frost arrives, and can be uncovered in early to mid-April of the following year. Greenhouse environment management: the temperature most suitable for tea growth inside the greenhouse is 20°C-25°C, with the maximum not exceeding 30°C and the minimum not falling below 8°C. On sunny days at noon, the temperature inside the greenhouse may exceed 30°C, and at this time the door must be opened
