A recent study conducted by a research team at the University of Wisconsin evaluated dry-matter intake (DMI) in more than 9,000 dairy heifers. The results provided new insights regarding heifer DMI. Among them:
- Heifer DMI as a percentage of body weight decreases as body weight increases, but the relationship is not perfectly linear.
- The DMI of dairy heifers is influenced by dietary neutral detergent fiber (NDF) concentrations.
- Low NDF diets increase DMI and high NDF diets decrease DMI in heifers of all sizes.
