How do newborn piglets prevent splayed legs?

Pig's splayed legs, also called "outer feet", are directly caused by muscle fiber hypoplasia. In production, the hind limbs of piglets split after birth, showing the shape of sitting dogs, making it difficult to walk; There are several front and rear limbs lying on the ground, unable to stand up at all. There will be eight-legged piglets in the normal production of pig farm A, but if it exceeds 3%, we should pay attention to it, find out the reasons in time and reduce the losses. (1) In recent years, the poor quality control of corn, soybean meal, wheat bran and other raw materials has led to the accumulation and even poisoning of mycotoxins in sows, which directly led to the serious splayed legs of piglets. (2) Production statistics show that the incidence of Landrace and Landrace is higher than that of three-line pigs, and they are hereditary. (3) Diseases that can cause reproductive disorders in sows may cause congenital splayed legs in piglets, especially circovirus infection and swine fever. (4) Inoculation of sows during pregnancy (especially in the later period) or some antibiotics with large side effects, high temperature and noise, as well as the occurrence of febrile diseases, will also aggravate the occurrence of splayed legs. Inbreeding will directly lead to the birth of other deformed pigs such as splayed legs. (5) In terms of feed nutrition, it is generally believed that the lack of selenium, methionine, vitamin E and choline in the feed of pregnant sows is an important cause of splayed legs. (6) The physical condition of sows is overweight or poor, especially overweight. (7) The mucus on the pig was not wiped clean when it was delivered. If you put them in an incubator with a smooth cushion, the floor will be smoother, and the newborn piglets may spread their legs because they have difficulty standing. B prevention and control (1) first of all, we must ensure the quality of feed and feed raw materials, choose high-quality products as far as possible, strengthen the construction and storage of feed warehouses, and prevent feed from deteriorating after arrival. (2) Control the corresponding epidemic diseases to ensure the health of pigs; Strengthen feeding management, properly control the physical condition of sows and reduce adverse stress. (3) Delivery and nursing of newborn piglets are very important. Try to dry the mucus on the pig as much as possible. If the insulation floor is smooth, you can put a clean and dry towel or sack on it to prevent the pig from slipping into the splayed leg. (4) Reduce the use of high-stress vaccines and antibiotics in the third trimester.
