Why the BOSS Brix Refractometer Is the Best Tool for Calf & Foal Colostrum Management

The First 24 Hours: The Most Critical Window in Livestock Health

The first 24 hours of a newborn calf or foal’s life determine its survival, immunity, and long-term productivity. During this short but vital window, colostrum intake provides the antibodies necessary to fight disease.

Failure to deliver high-quality colostrum leads to:

• Increased mortality
• Disease susceptibility
• Lower weight gain
• Reduced lifetime performance

The key to success? Measuring colostrum quality before feeding.

What Is a Brix Refractometer?

A Brix refractometer measures dissolved solids in liquid—used in livestock to estimate IgG levels in colostrum.
