Core Parameters Tables
Throughout 1987 and 1988, ten
subcommittees of extension spe
cialists representing various reg
ions in the United States prepared
fact sheets which described the
fundamental core parameters
deemed necessary for the elemen
tary use of DHIA records in the
following areas: Production
Change Analysis, Nutrition,
Reproduction, Health, SCC and
Mastitis, Genetics, Business Man
agement, Marketing, Youngstock,
and Culling.
The goal of these committees
was to identify the herd and indi
vidual cow measurements that
were readily identifiable and easi
ly measurable, as well as directly
usable by producers and important
for proper herd management.
The result of the committees’
efforts was a set of standardized
herd and cow management para
meters that represent all of the
important measures needed to
manage a herd and dairy farm for
the greatest profitability.
Because the goals of these
extension subcommittees reflect
the vision of DHIA, the Pennsyl-

vania Dairy Herd Improvement
Association has incorporated the
promotion, use, and refinement of
these core parameters into our
long term data processing deve
lopment and educational efforts.
Following are two sets of
tables. One, the Core Parameters
for Business Management Perfor
mance, shows groupings of herd
size ranges for several statistics
for each breed. This table has been
incorporated into DHIA’s year
end reporting.
The second set of tables was
new last year. These tables are
grouped by rolling herd average in
steps of 2000 pounds, from 14,000
pounds and under to 22,000
pounds and over. For all herds, the
average number of animals leav
ing the herds, and the number of
herds on test in each category arc
shown. In addition, the average
PTA milk, fat, and protein also
appear, as well as the lactation
average somatic cell count, and
the average number of days open.
