BULL DEVELOPMENT AND TESTS
|
Feed
The bulls have all been fed together except the two year olds. The ration consists of ground
corn, ground hay, silage, and a protein supplement. Our goal is to average 3.3 pounds A.D.G. We believe that fat bulls are not practical. The 3.3#
per day is enough growth for a group, knowing some will exceed this rate due to genetics or due to the bull's ability to consume more feed than others
(temperament, environment, etc.) The average daily gain will be available sale day.

Vaccinations and Wormer
The yearling bulls have been vaccinated with
Inforce 3 and poured with
Dectomax. The two-year-olds have also been given Inforce 3 and poured with Dectomax.

Bull Tests
Fertility Test
All bulls selling will have passed a comprehensive fertility test by David Kuntz, DVM. This includes collection, sperm count, morphology, motility,
and scrotal circumference measurement. The scrotal circumference is directly proportional to the age of puberty in that bull's daughters. The larger
the scrotal size, the earlier the puberty. As of now there is no adjustment for age, but 32 cm for a one year old and 36 cm for a two year old is
a good standard. Remember that a nine month old bull will have a good scrotal size at one year if he measures 29 cm. Scrotal measurements will be available sale day.

P.A.P. or Pulmonary Artery Pressure Test
The P.A.P. testing is done by Dr. Tim Holt of Fort Collins, Colorado. P.A.P is an indication of a bulls genetic
ability to tolerate high altitudes. The higher the P.A.P. score the lower the altitude the bull should be maintained at. Bulls that develop brisket may or may not have a genetic problem,
but may be the result of an environmental influence such as sickness, feed, or stress. Dr. Holt recommends that bulls with a P.A.P. score of greater than
48 be used at elevations lower than 6,000 feet.
