Abstract: The brewer′s spent grain (BSG) has nutritional characteristics such as abundant protein and phenolic compounds, low energy, and high fiber. In livestock and poultry production, BSG has good performance in improving reproductive ability, promoting the balance of intestinal microbial population, reducing feed cost, and increasing net income. Dietary replacement of a certain proportion of concentrated feed with BSG is recommended under the premise of fully considering the production stage and purpose of livestock and poultry.
