A cow-side milk test that indicates
the presence of subclinical ketosis

A convenient, cow-side test to diagnose subclinical ketosis (SCK) is now available for U.S. dairies. Keto-Test is a simple milk-dip test strip that changes color in the presence of abnormally high concentrations of circulating ketone bodies, which indicates the presence of subclinical ketosis.1

  • Subclinical ketosis typically occurs in early lactation when cows are in negative energy balance
  • An estimated 15% of cows in U.S. dairy herds have ketosis or subclinical ketosis2
  • The cost of a single case of subclinical ketosis (SCK) is estimated to be $783

Cost-effective screening program provides
a first step in preventing loss

The ease of use of Keto-Test provides dairy producers a cost-effective ketosis-screening program to help determine when further investigation of the herd’s health is warranted, and to help identify subclinical ketosis before it becomes clinical ketosis.

Keto-Test can readily be incorporated as part of a routine fresh cow program or for herd screening. Likewise, monitoring for subclinical ketosis can aid nutritionists and veterinarians in evaluating the dairy’s transition cow program.
