HerdFirst® Calf Feeds
Rumen development holds the key to success, which is why Cargill went beyond the protein basics and into the health of the gut to evaluate what really drove rumen papillae length. From our proprietary research into calf nutrition, we developed GutXpert™ advanced nutrition, to deliver the ideal environment for rumen development.
GutXpert™ advanced nutrition is the synergistic effect of our proprietary blend of key components to improve the gut health of the calf and properly develop the rumen:
- Better feed intake and transition from milk via rumen development
- Improved lower gut health, reducing risk of scours
- Maximized efficiency of nutrient utilization
