In recent years, with the global warming, most of China has experienced continuous high temperature in summer. The author's survey of pig farms in different regions shows that when the temperature exceeds 30 °C-33 °C, it is easy for livestock to not get enough nutrients due to the decrease in feed intake, the ratio of feed to meat is increased, and the production performance is degraded. The temperature and humidity provide a good breeding environment for the bacteria, causing the disease to spread. So how do you keep pigs productive at high temperatures during the summer? First, adjust the feed formula In the hot season, not only should we pay special attention to the quality of raw materials, but also prevent mold and water from being too large. More importantly, we should adjust the feed formula to ensure proper nutrient levels, ensure adequate intake of nutrients for pigs, and strengthen feeding management and animal husbandry. The environment within the house reduces the stress on the herd. Its specific practice: 1. Choose fresh, high-quality, palatable ingredients, and moderately reduce the proportion of crude fiber in the diet to reduce body heat. 2%-3% fat can be added to the diet because the oil has a small volume, high heat energy and less heat gain. 2. Increasing the protein level of the diet, fat pigs ≥16 pigs ≥16, high protein diet can increase the appetite of pigs and increase the feed intake of pigs. 3. In the high temperature environment, the metabolism of vitamins in the body is strengthened, and the demand for vitamins in pigs is also increased. At this time, moderately increasing the content of vitamins and minerals in the diet can alleviate the effect of heat stress on pigs. It is recommended to add 300mg/kg vitamin C, 200mg/kg vitamin E and 250mg/kg sodium bicarbonate to the diet. 4. Add Chinese herbal medicine additives to the diet. Chinese herbal medicine can comprehensively regulate the physiological metabolism of pigs at high temperatures, promote the growth and development of pigs, and improve the body's immune function. In the high temperature environment, a certain proportion of pig auxin (Chinese herbal preparation) is added to the diet of weaned piglets, which has a better promoting effect and can reduce the ratio of meat to meat and cost of materials. Chinese herbal medicines such as hawthorn, atractylodes, tangerine peel, betel nut, astragalus, Daqu, etc., which are used for appetizing and spleen-reinforcing and spleen-removing and heat-reducing functions, can be used as feed additives to alleviate the effects of hot environment on commercial pigs and increase weight gain and feed utilization. The Chinese herbal medicine, vitamins, minerals, electrolytes, etc. are formulated into additives according to a certain ratio, which can coordinate the regulating function of the pig body, enhance the adaptability of the pig and the ability to resist high temperature, thereby alleviating the heat stress of the pig. 5. Conditional pig farms can add extra green and juicy feed to the pigs. Second, improve feeding management 1. Scientifically arrange feeding time and increase the number of feedings. In the summer, due to the high temperature during the day, the weather is cool in the morning and evening, so that some adjustments should be made in the feeding time and feeding times. Specifically, the piglets are fed more than 6 times a day, and the fattening pigs and breeding pigs are fed 3 times a day. The feeding time is selected at 5-6 pm, 7-8 pm, and the lunch is avoided at noon. 2. Strengthen the ventilation of the pig house and do a good job in heatstroke prevention and cooling. Frequently remove the weeds around the pig house, open all doors and windows, keep the air circulating, conditionally install the ventilation fan, increase the ventilation of the pig house, speed up the air circulation speed of the pig house, and prevent the pig house from forming a high temperature and high humidity environment. However, when the outside temperature exceeds 30 °C, the effect of increasing the wind speed and increasing the ventilation on the cooling of the barn is greatly reduced. The intensive pigs basically adopt natural ventilation, and the temperature of the pig house is directly affected by the climatic conditions. Therefore, during the high temperature period in summer, only the temperature is controlled by cooling and cooling. When encountering extremely high temperatures (above 38 °C), emergency measures should be taken, such as spraying the pig body with water or spraying the roof, walls, floors, etc. of the pig house with water. Conditional pig farms can purchase power sprayers, and sprinkle and cool the pigs and their living environment 3-4 times a day. Organic Siberian Ginseng Extract
Organic Siberian ginseng extract powder is extracted from the roots, stems, and leaves of Siberian ginseng. Siberian Ginseng or Eleuthero has been used in China for 2000 years as a folk remedy for bronchitis, heart ailments, and rheumatism, and as a tonic to restore vigor, improve general health, restore memory, promote healthy appetite, and increase stamina.
Referred to as [Ci Wu Jia" in Chinese medicine, it was used to prevent respiratory tract infections as well as colds and flu. It was also believed to provide energy and vitality. In Russia, eleuthero was originally used by people in the Taiga region of Siberia to increase performance and quality of life and to decrease infections.
