The phenomenon of negative weight gain in piglets within one week after weaning is called systemic wasting syndrome after weaning. According to many years of breeding experience in many pig farms, grasping the feeding and management of pregnant sows, raising the birth weight of piglets and the lactating rate of sows are beneficial to the prevention of the disease.
The traditional pregnant sow feed pattern is "grabbing two in the middle". This method is more general in terms of time, and it is not easy to grasp the timing of arguing. Excessive fertilization results in too much sow and a reduced feed intake at later stages, which affects the growth of the embryo during embryonic development and the development of the mammary glands. According to the developmental rules of embryos and mammary glands, the gestation period is divided into 5 stages, and the animals are bred according to different requirements to increase the birth weight of the piglet and the lactation rate of the sow so as to obtain better piglet birth weight.
