Improve dairy cow health and milk performance with optimized vitamin D levels

Why Vitamin D Matters

Vitamin D plays a critical role in dairy cow physiology:

• Supports calcium and phosphorus metabolism
• Strengthens immune defense
• Promotes milk production and protein synthesis

However, research shows many dairy cows do not achieve optimal vitamin D status with conventional supplementation.

The Solution: Hy-D®

Hy-D® contains 25-hydroxyvitamin D3, a highly available form of vitamin D that helps cows maintain optimal vitamin D levels.

Benefits observed in trials include:

• Increased milk yield
• Improved calcium and phosphorus balance
• Reduced somatic cell counts
• Stronger immune function
