Key points of management and health care techniques for lactating sows

   1. Strengthen the cleaning and disinfection of perinatal sows: one week before ① parturient sows enter the delivery room, clean and disinfect the delivery room, then wash the parturient sows one week before delivery, and then enter the delivery room after disinfection with compound aldehydes. ② washed the abdomen, breast and vulva of sows with compound iodine solution 2 hours before delivery, and squeezed out the nipple plug of the lactation hole by hand to make the sows milk smoothly. During ③ midwifery, the hands and utensils of the midwifery staff should be strictly disinfected and the whole process should be kept clean. The abdomen, breast and vulva of sows were disinfected after ④.

   2. Provide a quiet and comfortable delivery room environment: the suitable temperature for ① delivery room is 22 ~

24 ℃, high temperature can cause dystocia, delayed delivery, more stillbirths, sow constipation, decreased feed intake, insufficient lactation and delayed estrus after weaning. ② keeps the delivery room clean, dry and well ventilated. Generally do not wash the birth column with water, because the column is wet and dirty, bacteria are easy to grow and reproduce in large numbers, and infect piglets and cause dysentery. Piglets with dysentery can be covered with powder disinfectant, and then cleaned with a mop dipped in disinfectant. ③ keeps the delivery room quiet and comfortable. Do not frighten, whip, drive away sows and startled piglets at will, this will often make sows in a state of mental tension and interfere with sow lactation.

   3. Purify pathogens in perinatal sows: perinatal period is the period when sows are most susceptible to infection. At this time, antibiotics are added to perinatal sows to reduce bacteria in vivo and in vitro, reduce vertical transmission, and prevent the development of cervitis, mastitis, non-milk syndrome (MMA) and bacterial diseases (diarrhea) in piglets.

000g or 200g doxycycline has good preventive effect. The results showed that the traditional Chinese medicine "Fu Milk" was added to the feed of perinatal sows.

It has obvious effect on increasing colostrum yield and whole-stage milk yield, and on improving piglet survival rate and weaning weight.

   4. Prevention of postpartum infection: ① intramuscular injection of Chloroprostol at 8 am on the prenatal day can not only prevent the occurrence of MMA in sows, but also control the delivery of sows in the daytime, shorten the stage of labor, and increase the survival rate of born piglets. Intramuscular injection of long-acting oxytetracycline 10 ml after ② or 2.5% during delivery of the second piglet

Ofloxacin 20ml, Houttuynia cordata injection 30ml, multivitamin 20ml, vitamin C 20ml, glucose buried saline 500ml, mixed intravenous drip, when the last 100ml was injected, add oxytocin

30 ml continued to drip, and the second day after delivery, Qinggong Zhuyanbao was infused into Ziqi, which is effective in preventing postpartum infection. ③ was injected intramuscularly with cloprostol oxytocin at intervals of 3 inches for 4 times in postpartum women without breast milk, and was fed with lactation herbs.

Promote lactation.

   5. Prevention of perinatal sow constipation: prenatal constipation can cause loss of appetite, reduce piglet birth weight, postpartum sow constipation will cause sow lactation disorder and piglet hunting dysentery, reduce piglet weaning rate, sow constipation is generally solved by adjusting the amount of crude fiber in sow diet. If sows discharge dry, hard, granular feces, each sow is fed with 50 grams of artificial salt or 25 grams of magnesium sulfate per day. Conditional pig farms can be fed with green feed and provide adequate clean drinking water.
