Found this on one of Maryland's information pamphlets or PDF.
Deer Research and Data Use eer Research and Data Use
In 2013-2014, 4,384 deer were examined at
butcher shops across the state during the muzzleloader
and firearm seasons. At the butcher shops,
sex and age of the deer were determined and antler
measurements were recorded for bucks. Deer were
also checked for evidence of illness or disease.
The yearly sample of harvested deer provides
valuable information that is used to estimate deer
population numbers and to detect any changes in
the deer herd reproductive potential. It is also used
to monitor the overall health of deer and the effects
of changes to seasons and bag limits made to better
manage deer populations.
Staff and volunteers determine the age of each
deer by the wear and replacement of its teeth. As
young deer get older their milk teeth are replaced
with permanent teeth. As adult deer age, their
permanent teeth begin to wear down. This enables
biologists to reliably categorize deer as fawns (less
than one year old), yearlings (approximately 1.5
years old) or adults (two years and older). The
proportions of deer in each age class and their
gender are then used in reconstruction models
to develop and follow trends in the state’s deer
population.
The antler beam circumference measurements
of yearling male deer that are brought to butcher
shops are used as indicators of the reproductive
potential and health of the deer herd. Yearling
males in good habitat with moderate deer numbers
will have larger antler beam diameters than those
in higher populations or poorer habitat. Abundant
food and modest competition translates into
more energy available for antler growth. This is
most evident in the yearling age class. Trends in
these measurements can indicate deer herd overpopulation
and habitat degradation. Overall,
Maryland’s long-term data for these indicators
show healthy, productive deer populations across
the state (Table 9).
Deer at the butcher shops are also examined for
evidence of hemorrhagic disease; a virus spread
by biting midges. Hemorrhagic disease (HD), or
“Blue-tongue”, commonly appears in late summer
and early fall. Deer that have survived HD and
are harvested will exhibit hooves with sloughing
or peeling tissue. These deer are still suitable
for human consumption. HD occurs yearly in
Maryland, although it varies in intensity. The
results of this yearly, statewide examination are
reported to the Southeastern Cooperative Wildlife
Disease Study (SCWDS) in Athens, Georgia as
part of a nationwide survey. The HD study with
SCWDS is one of the oldest and most complete
nationwide wildlife disease investigations in the
country
Also would appear that your states antler restrictions seem to be rather liberal in that either a double fork horn or a single 3 point or above can be taking in conjunction with does throughout the season. If this is wrong please correct me.
If a state is using antler restrictions in conjunction with doe tags then age structure/ and population is probably the goal. If you had more sever antler restrictions but no doe tags then I would say trophy might be the more emphasis as this indicates they butchered a better well rounded plan for emphasis on older bucks which as you mentioned does the deer herd no good.
