First, what is the disease in the pig farm in winter and spring? The sudden drop in temperature in the winter and spring seasons makes the temperature difference between day and night very large, which brings great difficulties to the heat preservation and disease prevention of pig farms. First of all, the sudden change in temperature makes the immunity of pigs decline. The defense barrier of the body is difficult to resist the invasion of pathogens. The wind also increases the probability of transmission of pathogens. The dry climate causes damage to the respiratory mucosa. These adverse conditions make the pathogens more easy to settle in the respiratory epithelium, respiratory flu, swine fever, PRRS, circovirus disease, pleural pneumonia prone. Secondly, low temperature causes the animal to secrete more adrenaline to resist the cold, and these hormones change the intestinal secretion mechanism, leading to changes in intestinal pH, intestinal flora imbalance, active bacteria active, and increased diarrhea. Therefore, it is particularly important to prevent respiratory diseases and diarrhea in winter and spring. Second, how to prevent pig disease in winter and spring It is not advisable to cure this disease, and it is not advisable to focus on improving the disease resistance of pigs. How to improve the immunity of pigs is the root of improving disease resistance. It is recommended to use the immune booster -- antiviral No. 1. According to the relevant experimental analysis, Antiviral No. 1 can promote the development and weight gain of the immune organs of young animals, promote the differentiation and maturation of spleen T lymphocytes, and produce leukocyte-mediated II, activate and regulate the body's immune function, and effectively enhance humoral and cellular immunity. The system is active, thereby improving the body's immunity, so as to improve the disease resistance of the animal. Clinical trials have shown that antiviral No. 1 can effectively control immunosuppressive diseases mainly composed of rings and blue ears, and control the occurrence of respiratory syndrome. The method of use is as follows: 1. Use the drug in two stages: 1 After weaning, the anti-virus No. 1 (500 g / 500 kg feed) mixture is used, and the course of treatment is 7 to 14 days; 2 After the nursery pigs are transferred to the fattening house, the anti-virus No. 1 (500 g / 500 kg feed) mixture is used, and the course of treatment is 7 to 14 days; 2. For the first time, you can take a course of treatment at any time after weaning, and then take a course of treatment every 14 days. 3. The disease has already occurred on the farm. It can be added with 300 PPM of 70% water-soluble amoxicillin co-mix.
