About the Product

Select Plus PR 32 and 40 are a convenient, economical means of supplementing your cow/calf herd. Select Plus PR 32 and 40 can help you have a more uniform cow herd and heavier weaning weights on your calves. Even the timid cows that typically do not get their fair share have equal access to Select Plus PR 32 and 40. This means more bred cows that can have earlier calves, heavier average weaning weights and fewer good cows culled each year.

Programmed Release (PR)
A unique manufacturing process involving utilization of economical non-protein nitrogen in Select PR 32 and 40. By slowing the release of ammonia from urea in the rumen, Programmed Release allows rumen bacteria additional time to convert more ammonia into bacterial protein for use by the animal.
