The Tend-R-Leen program, first introduced in 1963, created the concept of low-roughage feeding for dairy and beef steers. Today, the program continues to provide the lowest cost per pound of gain, 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 13-14 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.

“We feel we have more control for risk management with the steers.  Feeding steers on the Tend-R-Leen program is a marketing opportunity for some of our excess corn. We feed the corn up to 18% moisture from an air-dry system and we benefit from having lower drying costs.  We like that the steers offer a diverse revenue source.” – Shorty and Tom Crosby of River Valley Dairy, LLC

“There is less manure to deal with and the labor needed for the steers doesn’t interfere with the labor for our cropping and dairy cattle.”  – Mike and Corey Enright of Highland Dairy
