THE ALL-PURPOSE TYBAR COW
The TYBAR is a tough place for a cow to stake out a career. We demand she have a long list of important qualities. In order for her to express these qualities she must have a genetic background that includes many of the outstanding sires in the Angus breed.
However, one of the things we have to do at the Tybar is to screen potential herd sires for their ability to produce calves with good PAP scores. This process involves breeding the sire to a group of our cows with known PAP Scores. It takes two years to produce calves from these matings.
We have more than 185 PAP producing dams and are the only herd in the USA with PAP EPDs on every dam and the offspring produced.
It is very important for our cows to breed back every year. And, if she continues to perform well we like to keep her because longevity is important in our herd.
David and Emma Danciger of Tybar Ranch, Carbondale, Colo., were awarded the 2007 BIF Pioneer Award.
It is important to have cows with functional udders, structural soundness, good conformation, and fleshing-ability. Like begets like is an old saying in the cow business, and one that should be honored. Just having great EPDs and a stacked pedigree is not enough for Danciger Tybar Ranch. You can count on us to continue to provide the very best in genetics. We are in business to breed animals that will make money for our customers.

Tybar Genetics for the Future
Danciger Tybar Ranch is working hard to produce seedstock for the future needs of ourselves, our customers, and the packing industry. In order to plan for the future we must recognize the diversity of the cattle our customers produce. All cow herds have different environmental and physical constraints. All breeders strive to produce the best cattle their environment and operation conditions will allow.
In order to inform our customers, Danciger Tybar Ranch provides all the information available on every animal for sale. This process begins by locating and using the best AI sires available. As registered seedstock breeders it is our goal to use genetics focused on profitability and productivity. Both weight and carcass EPDs are evaluated, along with careful visual appraisal. An equally important consideration in this selection process is PAP (Pulmonary Arterial Pressure). PAP or brisket disease (High Mountain disease) is a concern for beef cattle producers who raise cattle at altitudes above 5,000 feet.
Surveys have confirmed the economic impact of brisket disease, which is caused by hypertrophy of the right ventricle of the heart resulting from pulmonary hypertension, which is caused by a shortage of oxygen. The availability of oxygen is 17% less at 5,000 feet than it is at sea level; 20% less at 6,000 feet, 26% less at 8,000 feet, and 31% less at 10,000 feet. The oxygen shortage at high elevation causes increased resistance to blood flow in small arteries of the lungs. The heart compensates for higher resistance by stretching and building up a high pressure. The pressure can continue to build up until fluid leaks out of the blood stream and collects in the chest cavity, the brisket, and other places. Eventually, the heart wears out and stops beating.
The underlying factor of brisket disease is increased pulmonary resistance that accompanies high altitude environments. Since, PAP has been shown to be highly heritable it has been used, since 1983, as a selection tool to help Danciger Tybar Ranch manage the risk associated with producing cattle at elevations over 5,000 feet. PAP testing every animal in our program for the last 30 years has provided access to a large database of information. This information is collected by Dr. Tim Holt, DVM, and analyzed by the Department of Animal Sciences Center for Genetic Evaluation of Livestock at Colorado State University. To date, there have been over 280 A.I. sires tested.
The data that has been collected for all of these years has helped Danciger Tybar Ranch and Colorado State University (CSU) formulate a PAP EPD for every cow and sire in the Danciger Tybar Ranch herd. WE NOW HAVE PAP EPDs to add to our breeding toolbox!
This information combined with 3,400 PAP records allows Tybar to produce breeding stock that will add to the profitability and productivity of cattle produced at elevations of 5,000 feet or more. Since 1991 the genetic trends for Danciger Tybar Ranch PAP scores has gone down, with the average PAP scores running 38 to 42.
Careful analysis of weight and carcass EPDs and PAP are not enough. We also pay close attention to the birth weight EPDs for every planned mating. We all know there is no profit in a dead calf and the repercussions of assisting at birth are costly.Private Treaty Bred Heifers are now available. For information, contact us at
