Description

technical field [0001] The invention belongs to the technical field of animal feed additives, and more specifically relates to a traditional Chinese medicine compound superfine powder feed additive for weaned piglets, and also relates to a preparation method of the feed additive. Background technique [0002] In order to improve the productivity of sows and reduce feeding costs, modern intensive pig farms advance the weaning age of piglets to 2 to 4 weeks old. Due to factors such as leaving the sow early, mutations in nutritional sources and other stressors, early weaning can easily lead to decreased immunity of piglets, intestinal microecological disorders, gastrointestinal mucosal lesions, and inability to digest and absorb dietary nutrients normally. At the same time, it causes a series of changes in the blood, endocrine and nervous systems, which leads to diarrhea, malnutrition, growth retardation, and death in severe cases. According to inve...
