Abstract

Under the background of antibiotics banning and zinc oxide reduction in feed, the intestinal health of weaned piglets becomes a key problem in swine production. In recent years, many kinds of products and technologies focused on improving intestinal health of weaned piglets have got much attention. In this paper, we reviewed the effects of probiotics, acidifiers, enzyme preparations, plant extracts, feed processing technology, and low-protein diet on the intestinal health and growth performance of weaned piglets. In addition, the classification of intestinal health grade of weaned piglets was performed based on the data from our team in recent decades, and the antibiotic-free nutritional strategies for different grades of intestinal health of weaned piglets were provided in this paper. It is providing references for the preparation of antibiotic-free feed for weaned piglets.
