Enhancing Feed Efficiency in Beef Cattle through Improved  Rumen Digestive Capacity, Feeding Behavior, and Microbiome Composition
The high efficiency of LRFI (Low Residual Feed Intake) in beef cattle feed is attributed to several factors, including higher digestive and utilization rates of nutrients in their digestive tract, superior energy utilization, lower metabolic energy expenditure, distinct rumen fermentation characteristics, differences in microbial composition, and alterations in fat metabolism and feeding behavior. These factors collectively contribute to a comprehensive set of changes.
