In 1988, brothers, Carl and Tom Wulff founded Wulff Brothers Livestock (WBL). The operation started in Woodland, California. Today the ranch is owned and operated by Carl and Heidi Wulff and family in Cheney, WA.

WBL co-founded the Black Gold Bull Sale in 1996. The sale is held annually on the second Thursday in September at the Colusa County Fairgrounds and includes fall and spring yearling bulls.

WBL is also a long time supporter of the Red Bluff Bull and Gelding Sale consigning bulls, and females for the online sale, nearly every year. WBL won the 2013 Reserve Champion Range Ready Bull, Wulffs Iron Mountain 142, and Reserve Champion Calving Ease Bull over all breeds, Wulffs Game Day 146!

WBL has always believed in and maintained a line-bred cow herd with an objective to increase productivity and longevity; cattle with high performance that required little intervention from the producer. With this goal in mind, WBL produces cattle that maintain great conditioning and body score with little feed and nutritional supplements.

The WBL cow herd has been developed around two cow families “Bands Sarita” and the famed “Erica Dianna.” The foundation of the two cow families was established with Wulffs Bands Sarita B708 and Wulffs Erica Dianna C116.

The “C116” cow is the greatest Tehama Band 155 daughter ever produced by WBL and some say the best they have ever seen! C116 has produced sale-toppers, bull-test champions, show winners and cattle that are sure to impress.

C116's best noted son is Wulffs EXT 6106, the famed Genex calving ease specialist. There has been a resurgence on 6106 due to his ability to produce females that have longevity, soundness and the greatest set of feet and legs to be found. Longevity speaks for its self; WBL currently has a 14-year-old full sibling to 6106, Wulffs Erica Dianna 9307, in production.
