The key to easy management in summer pig houses. In general, summer brings high temperatures and humidity, making it a challenging time for pig farming. Mosquitoes and flies thrive during this season, which can lead to serious issues for farmers. If not properly managed, these conditions can cause diseases and significantly affect productivity.
First, high temperature has a major negative impact on pigs. When the environment becomes too hot, pigs reduce their feed intake because their bodies try to minimize heat production. Even though digestion may slightly improve, it’s not enough to compensate for the loss of nutrients. Additionally, the increased effort to dissipate heat raises energy consumption, leading to lower feed conversion rates and reduced growth performance. High temperatures also negatively affect reproductive efficiency. Heat stress reduces sex hormone levels, lowering the estrus rate in sows and increasing the risk of miscarriage. In boars, high temperatures can damage testicular tissue, impairing sperm development and reducing semen quality, which ultimately affects sow fertility.
Second, high humidity worsens the situation. At high temperatures, pigs mainly cool down through evaporation from their skin and respiratory tract. However, when humidity is high, the difference between the moisture content on the pig's body and in the air decreases, limiting evaporative cooling. This makes it harder for pigs to regulate their body temperature, increasing heat stress. Moreover, high humidity promotes the growth of harmful microorganisms and parasites, raising the risk of infections like dermatophytosis, eczema, and even swine paratyphoid or diarrhea. It also increases the spread of infectious diseases such as swine fever and erysipelas.
Third, harmful gases like ammonia, hydrogen sulfide, carbon monoxide, and carbon dioxide can be dangerous. For example, when ammonia levels reach 38 mg per cubic meter, it can slow weight gain in pigs. At higher concentrations (70-110 mg/m³), it can cause respiratory problems, sneezing, and nasal discharge.
In addition, the proliferation of mosquitoes and flies in summer can disturb pigs, contaminate feed and water, and increase the spread of diseases.
To mitigate these challenges and improve economic returns, several effective measures can be taken:
First, using new ecological fermentation bed systems instead of traditional concrete pens. These systems keep the house cool in both summer and winter, maintaining a stable temperature around 20°C. They are clean, hygienic, and nearly free of pests. The fermentation bed breaks down waste effectively, reducing harmful gases and protecting the environment. It’s also easy to maintain and manage.
Second, improving the structure of the pig house. Using materials with low thermal conductivity for the roof, such as ventilated roofs or insulated panels, can reduce heat penetration. Insulating walls with materials like hollow bricks or aerated concrete blocks also helps.
Third, implementing additional strategies. Ensuring good ventilation by using windows, fans, and skylights can lower indoor temperatures. Planting trees and shrubs around the house provides shade and improves the environment. Providing sufficient clean water is essential, especially in summer. Adjusting feeding times to cooler hours, like early morning or late evening, can help pigs stay comfortable. Finally, adjusting feed formulas by adding baking soda, vitamins, and oils can support pig health and performance during the hot season.
Chili Whole
Dried chili peppers and chili products have always been commodities in international trade as seasonings. Dried chili peppers and chili products are important export seasonings in China. Chili is an important vegetable and seasoning, deeply loved by the people of China, especially in provinces such as Gansu, Shaanxi, Sichuan, Guizhou, Yunnan, Hunan, Hubei, and Jiangxi. Chili peppers can be stir fried, boiled, salted, eaten raw or made into Chili Powder, fresh chili sauce for consumption, and can also be made into chili oil. Chili is an indispensable and important raw material for the production of pickled vegetables. Eating chili peppers can enhance appetite, aid digestion, and have medicinal effects. Chili peppers can also extract chili red pigment, which is used in the food and cosmetics industry.
Chili peppers are produced in various countries around the world, mainly including Pakistan, India, North Korea, South Korea, Japan, China, Thailand, Mexico, Spain, Nigeria, Bangladesh, etc. The main exporting countries include Pakistan, India, China, etc., with Pakistan and India having the highest exports. Dried chili peppers are exported from Shanxi, Guangxi, Shandong, Hunan, Guizhou, Shaanxi, Sichuan, Henan, Hebei, Hubei, Tianjin and other places in China. China exports approximately 30000 tons of dried chili peppers annually, mainly to countries such as Japan, the United States, Malaysia, Singapore, and Sri Lanka.
