Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to a Chinese herbal medicine extract for weaned piglets and a preparation method thereof. Background technique [0002] In modern pig production, early isolation weaning technology is often used in order to give full play to the best production performance of sows, reduce the probability of piglet infection and improve piglet production performance. The digestive system of early weaned piglets is not fully developed, and it is difficult to withstand the nutritional stress caused by the transition from liquid breast milk to grain-based solid feed; the psychological stress caused by the sudden separation of piglets from the mother; and the process of regrouping and status determination of piglets Environmental stress caused by fighting among individuals. The triple stress of nutrition, psychology and environment inevitably increases the susceptibility of post-weaning piglets t...
