[0003] The period from 7 days before farrowing to 7 days after farrowing is called the perinatal period of fragrant pigs. The feed supply of fragrant pigs during the perinatal period is particularly important, because the perinatal period is related to the reproductive performance of sows, and it is the key point of the breeding process. Difficulties, pig farms encountered many difficult problems at this stage, including constipation, prolonged labor or dystocia, fever caused by postpartum inflammation, low feed intake, no lactation, poor uniformity and low survival rate of piglets, sows cannot Timely estrus mating or low mating rate
