Description

technical field [0001] The invention belongs to the technical field of piglet feed, and in particular relates to a Chinese herbal medicine feed additive for promoting growth of piglets and a preparation method thereof. Background technique [0002] Early weaning of piglets is a key technology for intensive pig production at home and abroad. It can improve the fertility of sows and the utilization rate of pens, improve the production performance and carcass quality of piglets, shorten the production cycle of intensive pig farming, and improve the economics of pig farming. benefit. However, due to changes in physiology, psychology, nutrition and environment, it will cause great stress to weaned piglets, causing physiological diseases such as diarrhea, decreased feed intake, growth retardation and reduced immune function in piglets, that is, early weaning syndrome, which is severe Affect the growth performance of piglets, even death. According to reports, the annual average i...
