ISSUE FOCUS 26 FEED & ADDITIVE MAGAZINE November 2023 limiting the impact of early stresses on the digestive system and ensuring optimal rumen development. In addition to good management practices, producers can include beneficial nutritional tools to help maintain calf health, support starter intake and reinforce rumen papillae development for optimal adult performance. Well-researched tools include probiotic live yeast such as LEVUCELL SC, and innovative yeast fractions such as YANG. References 1. Abuelo A., C. Faith, A. Hanes, J. L. Brester. 2021.
