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 are also on the rise, which can lead to many negative effects on pig producers. If not properly managed, diseases can spread quickly, causing losses.
Firstly, high temperatures have a significant impact. When the ambient temperature is too high, pigs experience reduced feed intake because their bodies try to limit heat production. Although digestion might improve slightly, this isn't enough to compensate for the nutritional loss. The increased energy required for heat dissipation further reduces feed conversion efficiency, affecting overall productivity. High temperatures also lower fertility rates, as heat stress can reduce sex hormone levels, leading to lower estrus rates in sows and higher rates of infertility. For boars, high temperatures can damage testicular tissue, reducing sperm quality and lowering sow fertility.
Secondly, high humidity worsens the situation. At high temperatures, pigs mainly lose heat through evaporation from their skin and respiratory system. However, when humidity is high, the difference between the water vapor pressure on the pig's body and the air becomes smaller, reducing evaporative cooling. This makes it harder for pigs to stay cool, increasing heat stress. Additionally, high humidity promotes the growth of harmful bacteria and parasites, raising the risk of infections like dermatophytosis, eczema, and even swine fever.
Thirdly, harmful gases such as ammonia, hydrogen sulfide, and carbon dioxide can accumulate in pig houses. Ammonia levels above 38 mg/m³ can negatively affect weight gain, while levels between 70-110 mg/m³ may cause respiratory issues, sneezing, and nasal discharge.
In addition, mosquitoes and flies in summer can disturb pigs, contaminate feed and water, and spread infectious diseases.
To reduce these challenges and improve economic efficiency, several effective measures can be taken.
First, using new ecological fermentation bed systems instead of traditional concrete pens can greatly help. These systems keep the temperature stable around 20°C year-round, provide a clean environment, and prevent pests. They also break down waste efficiently, reducing harmful gases and protecting the environment. Maintenance is simple and convenient.
Second, improving pig house design is essential. Roofs can be made with materials that block heat radiation, such as ventilated or insulated panels. Walls can be constructed with insulating materials like aerated concrete blocks or color steel sandwich panels. Proper ventilation is crucial—windows, skylights, and fans can all help regulate temperature.
Third, additional strategies include:
1. Enhancing ventilation by adjusting windows and installing fans.
2. Planting trees and shrubs around the pig house for shade.
3. Ensuring adequate clean water supply, especially for fermented bed pigs.
4. Adjusting feeding times to cooler hours, like early morning or late evening.
5. Modifying feed formulas by adding baking soda, vitamins, and oils to support health and performance.
By implementing these practices, farmers can create a more comfortable and productive environment for pigs during the hot summer months.
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.
