Operation Details

The three breeds, are used in a structured controlled breeding system. Heteros/hybrid vigor is maximized by using an English breed (Angus), a Continental breed (Simmental) , and a Zebu breed (Brangus).

All females are registered with  the American Simental Association Total Herd Enrollment program Option D (see  https://www.simmental.org/site/index.php/the-requirements). Participation in the program requires an inventory of all Simmental registered cows that is updated yearly. This results in  having EPDs for all females.

To help ensure we produce the most reproductively efficiency females we can, for over 15 years we have only had one 65 day breeding season (45 days for heifers) and culled every open female every year .

We have two key objectives:

Produce calves that produce a high value carcass

Produce crossbred low maintenance females for us and others that produce these kind of calves every year and have a long lifespan

Crossbred cattle have hybrid vigor (Heterosis). Using three different breeds properly selected produces almost the highest level of hybrid vigor possible.  We use a breed from the British breeds (Angus), the Continental European breeds (Simmental) and from the Bos indicus, or Zebu breeds (Brangus) to do this.

(See the “Beef Sire Selection Manual” at (CLICK HERE) for the Beef Sire Selection Manual on Crossbreeding for a discussion on crossbreeding.)

Data is collected at every stage of production from breeding to harvest, linked to sire and dam, and, along with EPDs, used to identify the females and bulls that can meet the production objectives.

Our rigorous attention to detail and disciplined enforcement of the industry proven standards we use gives us confidence that we are selecting those females that have the highest probability of being productive for many years (at least 8 or more years is our target).  We share all the data we collect on every animal in our herd. We share all the processes we follow in producing these cattle. We are constant learners and we constantly share what we are learning.

We have had only ONE  breeding season (65 days) for over 15 years and all females weaned a “productive calf”  EVERY YEAR or they were/are culled. The heifer breeding season is 45 days. Females get no second chance to get pregnant. This is the best way we know to produce females that meet the objectives.

Four year old and older cows (mature cows) only get grass year round. Younger cows get some supplement until they are mature.

Since 2001 only pure bred registered bulls have been used.

All data of all cattle is in the American Simmental Association(ASA) system. All cattle are registered with ASA in the Total Herd Enrollment program for Commercial cattle and have EPDs. See the ASA Total Herd Enrollment requirements at  ASA Total Herd Enrollment Requirements

“Productive calf” requirements: Weans greater than 80 “weaning weight ratio”, grows during back grounding and stocker phases, produces a carcass with a value that exceeds the cost of carrying the cow for a year. Females get two chances, if they get pregnant, to produce a productive calf. After second non-productive calf they were/are culled.
