Drive milk components yield

Cows feel the heat long before you do. In fact, rumination drops when temperatures reach 72°F or higher.1,2

The result? Feed efficiency and milk component yield drop, too. So, your ration must work harder to keep your cows’ engines running strong all summer long.

Research shows Levucell® SC fed cows produced 0.20 lbs more milk fat and 0.16 lbs more protein than control cows, even during extreme heat stress.3

That means, dairy farmers can see a Levucell SC return on investment of $0.54/head/day based on milk component improvement alone.3,4

Rev up your summer rations and optimize rumen function with Levucell SC.
