Many pig farmers are worried that the piglets purchased from the market are susceptible to morbidity and death when buying pigs. This worry is not unfounded. Before the listing of piglets, many pig farmers use various means to make them as full as possible, and then immediately catch cages or pack them into sacks, and immediately feed them into the live pig market. After entering the market, the pigs were overcrowded and the piglets were overcrowded. They collided with each other and traded through scales and immunizations before reaching the new pig farmers. Due to the significant changes in the environment, feed, and feeding methods, some newly weaned piglets are temporarily unable to adapt and are in a state of high tension, resulting in dysfunction of the body's various systems, reduced resistance to disease, easy to induce and secondary to high fever, constipation and Many diseases characterized by diarrhea. In addition, pigs from all over the country gather in the crowded hog market. It is inevitable that sick pigs will bring in the source of infection and spread the disease. Therefore, the newly purchased piglets should strengthen their feeding and management, and take corresponding comprehensive preventive measures to reduce the occurrence of swine diseases. First, do a good job of preparing the piglets before entering the stalls. Thoroughly sterilize the pens and utensils. Farmers should prepare huts, utensils and feed before they are ready to purchase piglets. Thoroughly clean the pens, especially the pens that used to have diseased pigs in the past, but should be thoroughly disinfected. The disinfection of walls, floors, food troughs and drinking fountains can be done with alkali solution (or 10% to 20% bleach solution, 10% to 20% lime milk, 3% to 5% coal phenol soap solution, 2 The %-4% formalin solution, etc.) was sprayed and disinfected. Equipment such as shovels and brooms can be rinsed with clean water and exposed to sunlight. Second, raising pigs should be as far as possible self-cultivation in order to reduce the introduction of diseases. Pig farms and pig farmers do not have basic sow herds and rely on purchases of pigs from the market. If strict quarantine and isolation measures are not taken, It is inevitable that the disease will be introduced. Therefore, adherence to self-cultivation and self-support is a basic measure to prevent the introduction of the disease. The practice of raising pigs in various places has proven that any pig farm and pig farmer who adheres to self-cultivation and self-sustainability have a sound system for epidemic prevention, and rare or no infectious diseases occur. Pig farmers (especially pig farms) should try to establish basic sow herds and insist on self-cultivation and self-cultivation. Farmers are best to purchase pigs from disease-free pig farms and try not to buy them from the market to reduce the spread of the disease. In order to avoid unnecessary stress response of the pigs, the feeding of the piglets should be carried out step by step, and comprehensive measures should be taken to prevent the occurrence of diseases. The newly purchased piglets should be put into the pens for free movement. Familiar with the new environment, there should be a clean drinking water supply in the barracks, and it is best to drink 0.1% potassium permanganate water in the first week.When the piglets are looking for food, they can feed the appropriate amount of green and succulent feed and feed them later. A small amount of full-priced material is generally suitable for pigs to eat 70% to 80%, and after the pig is adapted to the new feeding method, it is allowed to feed freely. If farmers use the self-made mixture to feed pigs, appropriate amount of feed additives should be added. Or antibiotics.To enhance the gastrointestinal tract adaptability of piglets, appropriate amount of yeast tablets or rhubarb soda tablets may be added to the feed. After 10 days of feeding and observation, if the piglet feeds, drinking water is normal, can be to piglets Swine fever and swine erysipelas Immunization lung disease, piglets paratyphoid vaccine. Quarantine and then after 10 to 20 days, without the occurrence of disease, the insecticide, castrated before gregarious other pig rearing.
