And Poultry Science
There are two important buffer
ing systems in the body that main
tain body fluids at near neutral pH.
One is based on phosphate and the
other on bicarbonate. The latter
system is utilized in a clever way
by birds to form eggshells.
The origin of bicarbonate
(HCO3*) is from carbon dioxide
(CQz). which arises as a consequ
ence of metabolism of sugar,
mainly glucose. Glucose, which is

derived from complex carbohy
drates in the diet, is broken down
to release energy for metabolism.
Carbon dioxide is also formed as a
consequence of glucose
Carbon dioxide is of course a
gas, but gas doesn’t build up in
tissues. Instead, CO2 is converted
into bicarbonate which dissolves
into the body fluids. Within the
lungs CQz reforms and is exhaled
as a gas.
In the shell gland where the
eggshell is made, bicarbonate is
converted into carbonate (CO]*),
and this substance is secreted
along with calcium ions (Ca ++ )
onto the shell membranes which
cover the albumin, or-egg white.
The shell membrane catalyzes the
precipitation of calcium carbonate

Bicarbonate, carbonate, and car

Under normal circumstances,
bicarbonate is maintained at the
correct level in body fluid because
the breathing rate is just right to
remove CO2 at the same rate as it
forms within the body. Eggshell
formation taps into this
fering system. Changing the com
position of the buffering system
can profoundly affect eggshell for
mation. For example, if hots are
subjected to heat stress, they will
attempt to cool down by panting.
CO2 will be exhaled at a more
rapid rate than it is being produced.
As a consequence, total body CO2
is decreased and eggshells become
thin and fragile.
vation District is administering the
Pennsylvania Agricultural Non-
Point Source Pollution Abatement
Program’s Financial Assistance
Program in the Chester County
portions of the Octoraro Creek and
Elk Creek watersheds.
The sign-up period for this prog
ram is Match 13 through April 10.
Landowner participation in this
program is on a voluntary basis.
The financial assistance prog
ram is a cost-sharing program to
help landowners with the expense
of controlling critical agricultural
nutrient and erosion problems by
installing nutrient management
and conservation practices on their
farms during a period of one to
three years. The maximum cost
share rates available are eighty
percent (80 percent) of the costs
for certain practices and are not to
exceed $30,000 per landowner.
The ultimate goal of the prog
ram is to reduce the amount of nit
rogen, phosphorous, and sediment
entering the Chesapeake Bay
through its many tributaries, as
agricultural runoff was determined

as a contributing source of those
nutrients and sediment. However,
local benefits will also be realized,
from elimination of gullies in
fields and more complete utiliza
tion of nutrients on the term, to
increased quality of local streams
and reduced risk of contamination
of our groundwater.
Some of the basic eligibility
requirements for the financial
assistance program are as follows:
•Must be a landowner in the
Chester County portions of the
Octoraro Creek or Elk Creek
•Must have a critical nutrient
and/or soil erosion problem(s) on
the farm in these Watersheds.
•Must be a “cooperator” with the
Chester County Conservation Dis
trict. (If n °t> please request an
application form from the district)
•Must be willing to enter into a
one to three year agreement
designed to solve the critical nutri
ent and/or soil erosion problems in
the farm and maintain the agreed
upon practices for a 10-year
•Must be willing to follow a
nutrient management plan pre
pared by a district-approved agro
nomic consultant for the 10-year
Signing up for the financial
assistance program does not guar
antee approval in the program.
Only those landowners with seri
ous nutrient and/or soil erosion
problems will be evaluated by a
technical assessment and needs
determination of the farm com
pleted by the staff of the Chester
County Conservation District and
the Natural Resource Conserva
tion Service. Final eligibility
determination will be made by the
Chester County Conservation Dis
trict board of directors. Eligibility
may also be postponed because of
