First, repair the pig house, do a good job in disinfection: keep the pig house warm, dry and ventilated, do a good job in pig house hygiene, and pig pens are often disinfected to create an environment that is not conducive to the survival of germs. Pigs like to be warm and dry, especially those piglets whose thermoregulation function is not yet well developed, body surface fat is less, and cold resistance is poor. In early spring and March, the weather is changeable and the temperature difference between day and night is large, so it is very important to keep the pig house warm, the environment dry and clean, and the air smooth, and to create an environment conducive to the growth and development of pigs. Especially in the north, sows must give birth in the greenhouse to ensure that the piglets are all alive and strong.

Before the advent of spring, the pig house should be thoroughly disinfected to prevent the growth and reproduction of bacteria. Specific measures: first thoroughly clean the pigsty, then spray and paint the pigsty floor, walls and surrounding environment with 20% 30% lime milk or 20% plant ash or 2% 30% caustic soda solution, after washing the utensils, disinfect it with 3%-5% soda water, and then rinse with water.

Second, strengthen epidemic prevention, pay attention to nutrition: strictly prevent all kinds of infectious diseases. Do a good job of pig vaccination in strict accordance with the immunization procedure. Once an epidemic disease is found, it is necessary to strictly block, disinfect, strengthen preventive injection, and dispose of dead pigs as required. If an epidemic occurs in the surrounding area, in addition to doing a good job of disinfection, outsiders and vehicles should also be strictly prohibited from entering the pig farm, and their own vehicles and personnel should be thoroughly disinfected when they come back from the epidemic area.

Nutrition level also has a great impact on the health of pigs. High-level nutrition supply can meet the nutritional needs of pigs, ensure that pigs have a better physical condition, and improve the ability of pigs to resist diseases. Therefore, in the production, the full price diets with different nutrition standards were fed scientifically according to the different growth stages of pigs, and the diet formula was adjusted timely according to the body weight and intake of pigs. Lack of green feed in spring, try to add succulent feed such as carrots and brewer's grains and cake feed in the diet to improve pig appetite and supplement some vitamins at the same time.

Third, fine management and scientific feeding: the feeding and management of fattening pigs and breeding pigs can be carried out in accordance with the routine, but the feeding and management of piglets should be prudent. Due to the lack of innate immunity, thermoregulation and digestive function of piglets, in the spring with changeable climate, there are some mistakes in feeding and management, which can easily cause piglets to get sick and even die in large numbers. Therefore, it is necessary to improve the feeding and management of lactating sows, keep breasts clean and hygienic, and do a good job in feeding, supplementary feeding and vigorous feeding, so as to make piglets pass through birth, feeding and weaning safely, and weaning piglets should be specially cared for.

To prevent piglet dysentery, vaccination should be given to sows in the late stage of pregnancy, and attention should be paid to the cleanliness of postpartum environment and the improvement of piglets' physique. Pigs in each feeding stage should be fed full-price compound feed and add appropriate amount of compound feed additives. Provide clean drinking water, adequate light and proper exercise to promote the healthy growth of pigs and safely survive the disease-prone spring.
