Brisket Disease / PAP test Results
Galloway cattle have a long history of being Highly Resistant, if not immune to Brisket Disease. We are working with
Dr. Tim Holt, CSU and Mark Stayton, WY to substantiate anecdotal historical information with todays science & technology.
Holt - Utilizes PAP (Pulmonary Artery Pressure) testing to evaluate cattle 18 months and older. This is a heart catheterization
where a pressure reading is taken in the right atrium of the heart. Any cattle with scores over the #50 can not be moved to
altitude or they will develop Brisket Disease (which is essentially - congestive heart failure).
Cattlemen in the Rocky Mountain west
are having PAP scores taken and deciding "who" to move to altitude. These scores are also used in Sire Selection
as the disease is inherited and passed to progeny.
Our Cattle here at the DD Ranch were tested as a herd. Thus far 17 cows and our two main herd bulls have been tested.
We are very pleased to report that our scores ranged from a low of 30 to the highest score we had of 42 - all other scores
were in between with no single animal spiking out side that curve. We are attaching our "Work/Score Sheet"
from CSU for your review.

Stayton - His work evolves around isolating and identifying DNA markers for Brisket Disease. This work is very tricky
as he explained to me that some markers can be present and not activate the disease. Brisket Disease may also skip a
generation or skip a series of years. That is a problem as - just as you think the calf survives at altitude, he is 3-4 years
old and suddenly develops the disease. If quick action of moving the cattle down in altitude is not taken they die.
This research is on going at the University of WY at Larime. While
great progress is being made, the final answer still lies ahead. Once those markers can be positively Identified Galloway
breeders wish to test Registered Galloway Cattle and further substantiate the breed resistance.
