The interval between gestation, lactation, weaning and re-breeding of sows is the reproductive cycle of sows. In these three stages of the sow, the length of lactation can change. Lactating period, it is also best to use pig B-ultrasound to ultrasound the piglets and sows, after the inspection, the piglets can be weaned early, the lactating period of the sow can be shortened, so that the sow can enter the estrus and mating stage as early as possible, and the breeding cycle of the sow as a whole can be shortened, and the pig can also be continuously observed by B-ultrasound on the lactating sow. The shorter breeding period of sows can also improve sow utilization efficiency, and sows can produce more piglets.

B-ultrasound is used in pigs

Preventing sows from dystocia and shortening the labor process are important measures to reduce the accidental death of piglets and improve the production efficiency of sows. It is one of the most important tasks to do a good job of prenatal and postnatal monitoring of sows. The first is to sterilize the delivery house 2-4d before the sow gives birth to make the surrounding environment clean and sanitary. The second is to pay attention to reducing the amount of feed in the prenatal week, and appropriately add about 75% of the laxative in the feed, prenatal use of pig B-ultrasound to observe its intestinal condition, timely treatment when there is a problem, to reduce constipation during sow delivery. Prophylactic drugs were administered according to the epidemic dynamics of major diseases in pigs. The third is to do a good job in the preparation of iodine tincture, oxytocin, postpartum pig insulation equipment and other items required for artificial delivery, reduce sow dystocia and production time, sow prenatal dystocia to use pig B-ultrasound to observe the type and condition of dystocia. If there is sow dystocia can be injected with oxytocin, if not surgery, in short, reduce the mortality of piglets, which can improve the utilization efficiency of sows.
