Control reproductive disorders, actively carry out epidemic prevention work, prevent sows from getting sick, and regularly use pigs to check the reproductive system with B-ultrasound. Special precautions should be taken to prevent sows from getting sick during the later stages of pregnancy, otherwise it may lead to partial or complete embryo death. Large scale pig farms adopt self breeding and self raising methods to strictly prevent the introduction of reproductive diseases. Imported breeding pigs from pig farms outside the region must be strictly isolated and observed for at least one month to ensure the health of the purchased breeding pigs. It is also important to administer vaccines such as parvovirus, pseudorabies, and porcine reproductive respiratory syndrome to reserve sows before mating to prevent the occurrence of reproductive disorders. It is also important to perform pig ultrasound examination on reserve sows. Establish good hygiene conditions and improve the resistance of sows.

With the continuous development of large-scale pig farms, it is becoming increasingly important to improve the reproductive rate of sows. It can not only provide more piglets for large-scale pig farms, but also improve the economic benefits of large-scale pig farms. Pig ultrasound plays a very important role in improving the reproductive rate of sows. At present, with the continuous increase in the number of large-scale pig farms, the emphasis on the feeding management and reproduction of sows is still insufficient, and the survival rate of piglets produced is not high. Therefore, it is important to use pigs for B-ultrasound examination of sows and piglets during the breeding process. This series of problems directly troubles and restricts the development of the entire breeding industry, causing a decline in breeding efficiency and subsequently affecting the enthusiasm for pig farming.

Scientific feeding and management should be given to sows at all stages, creating a quiet and comfortable growth and living environment as much as possible, and fully tapping into the reproductive potential of sows. Other measures can also be taken to improve the reproductive rate of sows, such as drug aphrodisiacs, artificial insemination technology, embryo transfer technology, pig ultrasound technology, etc., to tap into the reproductive potential of sows and ultimately promote the development of the entire livestock industry.
