Three strokes can make sows have multiple births and high yield

? Strengthen the feeding and management of sows

Sows should be fed more roughage and green fodder during the empty period, the middle stage of pregnancy and the later stage of lactation. Sows should provide adequate amounts of protein, minerals and vitamins in early pregnancy, late pregnancy and early lactation. At the same time, it is necessary to provide a relatively stable living environment for sows and reduce the stress reaction caused by herding and driving as much as possible.

? Do a good job of giving birth to sows

For 5-10 days before delivery, the sow should clean the birth ring and spray and disinfect it with 10%-20% fresh lime water. Before giving birth, sows disinfect their abdomen, breasts and vulva with 2% to 5% Lysuer solution. After giving birth, sows should remove the mucus from the piglets' nose and rip off the fetal membrane. For fake dead piglets, first aid can be made by slapping the chest, lifting the hind legs or punching the nose with alcohol. It is necessary to do a good job of midwifery for dystocia sows to make them give birth smoothly. In addition, heat preservation is particularly important for newborn piglets. When piglets are born, the temperature of the delivery house must be kept at 26 ℃ ~ 32 ℃.

? Sows should be bred during lactation.

Piglets are weaned at the age of 35 to 40 days. In general, sows are given an aphrodisiac 3-5 days after weaning. Sows should be mated immediately after estrus to make them pregnant during lactation so as to increase the litter size.
