How to improve the survival rate of piglets?

In order to improve the survival rate of piglets, the following measures can be taken: (1) Strengthen the feeding management of pregnant sows, properly improve the nutritional level and increase the feeding amount before labor 1 month, so as to increase the newborn weight of piglets. Vaccines such as K88 can be injected into sows in the third trimester of pregnancy, so that sows can produce antibodies, which can be transmitted to piglets through milk, thus preventing piglets from diarrhea. (2) Do a good job of anti-freezing and heat preservation. On the basis of ensuring that the temperature of the production shed is about 20℃, a pig incubator is set in the production column, and a 250-watt infrared lamp is hung in the box with a distance of 40 cm from the bottom of the box, or an electric heating plate is laid in the box. (3) Prenatal 1 week to postpartum 1 week requires stress prevention and day and night care; Set up a baby pen in the delivery room to protect piglets and limit sow activities. (4) If newborn piglets eat enough colostrum and eat colostrum early, they can gain immunity and rich nutrition as soon as possible, produce body heat as soon as possible, and increase their cold resistance and disease resistance. (5) Fixed nipples If the suckling position of piglets is not fixed, it is bound to make weak piglets miss milking time because they can't catch nipples, starve to death or become stiff pigs. Therefore, within 2 days after birth, the nipples are fixed manually, and the weak ones are fixed to the front and middle nipples to make up for the congenital deficiency and ensure the uniform development of piglets in the whole litter. (6) Selective foster care When sows have too many litters to feed them all, the extra piglets should be fostered to other sows for feeding. (7) Iron supplementation: intramuscular injection of iron 100~ 150 mg per piglet 2~3 days after birth can not only prevent iron deficiency anemia, but also increase the average number of weaned piglets per litter by 0.5~ 1, and increase the weight at the age of 60 days by1~ 2 kg; In selenium-deficient areas, a mixture of 0. 1% sodium selenite and vitamin E should be injected at the same time, each head 1 ml, 10 days old each head 1 ml. (8) Feeding piglets can eat freely about 7 days after birth, that is, put granular materials in the feed trough to let piglets eat freely. In order to let the piglets eat as soon as possible, the piglets were rushed to the feeding trough 1 time in the morning and afternoon a few days ago, and the effect was good. (9) Correcting sow biting, wearing protective masks for sows, artificially forcing breastfeeding and other bad behaviors; Feed enough warm salt water to sows before and after delivery; The midwife should promptly remove the afterbirth discharged by the sow; Eliminate biting sows and so on.
