About The Tend-R-LeenĀ® Program

Providing the lowest cost per pound of gain since 1963.

The Tend-R-Leen program, first introduced in 1963, created the concept of no-roughage feeding for dairy and beef steers. Today, over fifty years later, the program has fed over 10 million steers and is the dominant leader in economic return for the producer.

The program is based on obtaining market weight within 12 months, creating a fully lean carcass.

It is ideal for existing dairy operations, as well as retired dairy producers, commercial feedlots, and calf growers. The Tend-R-Leen program offers producers a tested method to significantly supplement cash flow and operation returns with low inputs.
