Abstract： Beet pulp，a by-product of the sugar industry，has becomean essential fiber source for improving the rumen function of ruminant animals，due to its significant cost-effctivenessand environmentally sustainable characteristics.This article examined recentapplications，technological advancements，developmental prospects， application limitations，and trends concerning the utilization of beet pulp as animal feed.The analysis indicated a rapid expansion of its application from ruminants to various livestock and poultry sectors，including pigs， aquaculture，and poultry，thereby significantly enhancing itsmarket competitivenessas a low-carbon feed ingredient.Biological fermentation technology presents notable advantages in augmenting beet pulp protein content，facilitating oligosaccharide release，and improvinganimal digestibility，with expectations for largescale application in the future.Extrusion technology，asarelatively mature method，could efectively enhance feed digestibilityand nutrient utilization.However，research on itsspecific application to beet pulp feed remained insufcient.Thisreviewaimed to comprehensively explore the overall potential of beet pulp in constructing economically viable，resource-efficient，and environmentally sustainable feed systems，providing a theoretical basis and practical guidance for optimization in related industries（such as feed formulation optimization and raw material substitution schemes）and technological innovation （such as process improvement， and enhancing palatability and utilization）.
