The committee emphasized that
MUN is a valuable tool to add to
the information arsenal of dairy
men and their consultants. To
assist our members educational
programs and material must
include the lastest of research
findings.
News articles and research pap
ers will be written and distributed
so our members get the latest
information as it appears.
Approximately 900 members’
herds are tested monthly and
another 150 herds are on a testing
schedule every other or every
third month, averaging around
60,000 cows per month on MUN
analysis.
An additional number of cows
and herds ate being tested from
other DHIA associations in the

During hot, humid summer
months inadequate water intake
could elevate MUN levels.
Pa. DHIA is the only Dairy
Records Processing Center that
collects MUN analysis results and
disseminates the data for research
and field use.
Jim Boyer reported that our
processing center is now hooked
into die Internet and veterinarians,
nutritionists, researchers, educa
tors and dairy fanners can now
download MUN information from
the Internet
New Bolton Center and Pa.
DHIA are connected and MUN
summary information will soon be
available through New Bolton’s
Web page. Pa. DHIA also is deve
loping a Web page for direct
access to DHIA information
including MUN data.
Dr. Ferguson’s report compared
Pa. DHIA MUN cow information
with BUN (Blood Urea Nitrogen)

DHIA technician was in the herd.
He also tested the milk in their
lab using wet chemistry and spec
