Newborn piglets do not have immunity. Pigs and humans are different. Young children can obtain immunoglobulins from the placenta through the mother. However, unlike pigs, antibodies in the sow's blood cannot enter the fetus through the placenta. Therefore, the body weight of piglets after birth is almost zero. In an immune state. Colostrum contains a large number of antibodies (mother antibodies) that migrate from the blood of the sow. Although this antibody is a high-molecular protein, most of it can enter the piglet's blood through the intestine wall as it is, and it has a systemic immune response. Disease effect. However, the maternal antibody is absorbed as such for a limited time, and weakens with the extension of birth time, and terminates within tens of hours after birth. This termination phenomenon is called blockage. Therefore, the most critical factor for newborn piglets is the need to immediately ingest enough colostrum to obtain passive immunity. The sooner the colostrum is eaten, the better. Piglets can eat 3-4 times of milk within 12 hours after birth, and the total amount reaches 80-100 ml. Piglets can grow up healthily. The milk secreted within 36 hours after delivery is colostrum, and later secreted milk is often milk. Colostrum and regular milk not only provide sufficient full-price nutrition for piglets, but it is also the only source of passive immunity. Some of the antibodies that are not absorbed are called topical antibodies and can attach to the surface of the intestinal mucosa to prevent the invasion of pathogenic bacteria from the intestine and act as a local immune response. Therefore, colostrum plays a very important role in the systemic and local disease prevention of piglets. It is very difficult for piglets to eat colostrum to survive, and piglets that lack colostrum or eat too late have weak disease resistance and are prone to disease. Only eat enough colostrum, only strong resistance to disease, in order to grow healthily. In addition, as the piglets are born, some pathogenic bacteria such as E. coli and Salmonella enter the gastrointestinal tract and rapidly multiply. If the piglets cannot quickly eat colostrum, antibodies in the colostrum cannot inhibit the above-mentioned bacteria from multiplying, and the piglets may develop the disease. Especially diarrhea, so colostrum must be eaten within 12 hours after birth. Maternal antibodies that migrate from the colostrum to the piglet's blood are reduced at a certain rate and generally lose their protection 2-3 weeks after birth. At this time, the antibodies produced by active lymphocyte immunization of the piglets are still low, and the concentrations are low, and they do not produce strong. Protection, so that at the time of the passive immunization of maternal antibodies and the active immunization of the piglets, there will be an empty space for immune protection. At this time, the ability of piglets to resist infection is very fragile and it is a very dangerous period. The length of this period is closely related to how much colostrum is eaten. If colostrum is eaten much, this period is short. To make it easier for piglets to get through this period, it is best for piglets to eat enough colostrum. How do you get more colostrum for each piglet? This is a problem that the pig farms are most concerned about. On the one hand, it is very important for the pig farms to strengthen their feeding and management, especially for the care of newborn piglets in the delivery room. However, many pig farms can't do it completely. I hope everyone can strengthen management. In addition, the health status and nutritional supply of nursing sows are also very important. Good sows have good feed, enough milk, healthy sows, and healthy piglets. Shenzhen Sunson Tech Co., Ltd , https://www.sunsonkiosk.com
