Cattle Operation

The Singleton Ranches is a commercial cow/calf operation running approximately 10,000 mother cows, depending on the conditions of the range. The calves are held over and sold as yearlings. We also pasture stocker yearlings, bringing the total number of yearlings to approximately 40,000 head per year.

New Mexico Cattle Operation

Today, Singleton Ranches cattle operation in New Mexico tries to maintain 10,000 bred cows. The genetic history is diverse. We have origins with Brangus, Beefmaster and crossbred English cows. We introduced Angus bulls in 1999 and Hereford bulls in 2006.  Recently, proven calving-ease Red & Black Angus bulls were introduced to breed our yearling heifers. In 1999 we also started crossbreeding Robert O. Anderson registered Brangus cows, purchased with the Latigo Ranch, to high quality Angus bulls. We have developed an “in-house” seed-stock program that produces 100 to 150 quality yearling bulls for dispersal to all New Mexico divisions. This Black Angus influence dominates our commercial genetics today. We have crossed these genetics with Hereford to add weight to our calves and heterosis (hybrid vigor) to our replacements. Depending on the year and available grass we keep 25% of our heifer crop for replacements. Our production rules are simple-“cows must give us a good calf every year from the age of two or themselves to sell-no exceptions”.


In years with surplus grass the New Mexico divisions also seasonally pasture 3000 to 5000 outside Mexico steers with average gains of 250lbs.

California Cattle Operation

The Topo and Peachtree Ranches are located in Central California in Monterey and San Benito Counties. Each ranch consists of 45,000 acres. Prior to 2014, both ranches were operated as a cow-calf and a stocker operation. Due to drought conditions, the cows were shipped to the New Mexico Ranches in the spring of 2014.

Now as only a stocker operation, the Topo Ranch runs 10,000 steers, and the Peachtree Ranch runs 5,000 steers. Steers are received on the ranches from October - December and are shipped off May - June.

These two ranches are considered to be among the most productive ranches for yearling steers in California.
