Exploring Feed Efficiency in Beef Cattle: From Data Collection to Genetic and Nutritional Modeling

Increasing feed efficiency in beef cattle is critical for meeting the growing global demand for beef while managing rising feed costs and environmental impacts. This review examines the progression from traditional data collection methods to modern genetic and nutritional approaches that enhance feed efficiency. We first discuss the technological advancements that allow precise measurement of individual feed intake and efficiency, providing valuable insights for research and industry. The role of genomic selection in identifying and breeding feed-efficient animals is then explored, emphasizing the benefits of integrating multi-population data to improve prediction accuracy. Additionally, the paper highlights the importance of nutritional models that could be used synergistically with genomic selection, allowing for optimized feed management in diverse production systems. Combining these approaches provides a roadmap for reducing input costs and promoting a more sustainable beef industry.
