Objectives The advantages of applying ultra-fine grinding technology in the processing of feeds for ruminants were studied to provide reference for improving the quality of feed and the production performance of animals. Methods The principles of ultra-fine grinding technology and the application of this technology in the processing of feeds for ruminants were summarized by reviewing relevant literatures. Results Ultra fine grinding technology has significant advantages in improving the utilization of feeds, enhancing the palatability of feeds and the effectiveness of additives, and promoting the fermentation function of rumen. It can effectively improve the digestion rate and utilization rate of feeds, promote the growth and development of ruminants, and improve the health of ruminants. Conclusions Ultra-fine grinding technology is widely used in the processing of feeds, has a significant effect on increasing the quality of feed, the growth performance of ruminants, and economic benefits. This technology holds prospects for developing.
