From the heart of the Sinclair cow herd.

We’re offering a select set of yearling replacement heifers — from the heart of the registered herd - offered as commercials.

The same maternal genetics and cow-making power behind the bulls runs deep in these females. Deep-bodied, functional, and bred for longevity — the kind of cows ranchers keep for years.

Real cows start here.

Contact us if you’d like to add a set of foundation Emulation females to your program.
