Both genetic and environmental
differences will affect crude
protein level of corn gram. Usmg
“average” protein content in
ration formulation can be costly
because it is easy to either over- or
under-estimate. For this reason,
feeders should ascertain the
protein content of gram before it is
fed Samples representing gram of
different hybrids or of different
fields should be analyzed
separately.
Cultural practices, especially
nitrogen fertilizer rate, influence
grain protein content. In a
University of Nebraska ex
periment, percent crude protein of
com gram increased from 7 to 8.7
as mtrogen rate increased from
zero to 160 pounds per acre.
Inadequate fertilization can 'cut
both protein content and yield.
Don’t skimp on mtrogen fertilizer
if corn gram protein is of concern
Researcher have identified
certain hybrids that tend to have
higher gram protein content than
other hybrids grown under the
same conditions. The actual level
vanes from year to year and
location to location, but some
hybrids will consistently be higher.
It is not unusual to establish dif
ferences of up to two percentage
points between two popular
hybrids.
Is a difference of two percent in
gram protein content important to
a livestock feeder 9 It certainly is if
he has to buy protein supplement
to make up the difference If 44
percent soybean meal is used as an
example, the cost of a pound of
protein is calculated by dividing
the cost of a ton of meal by 880
(that’s the pounds of protein in a
ton of 44 percent meal) Thus, $250
for a ton of meal means each pound
of protein costs 28 5 cents.
Two percent of 56 pounds comes
to shghtly over one pound of
protein per bushel. If soybean

protein content, the higher protein
com is worth 28 cents to 30 cents
per bushel more. If 150 bushels of
com per acre are produced, the
value of a two point difference in
protein content would come to over
$4O per acre'
These values will differ with the
price of supplement and yield
level. Also, hog and poultry feeders
have to be more concerned with
ammo acid balance and, m this
case, com protein and soybean
protem are not equal.

A CRAWLING START
Indications that the whole milk

evident as the new year got off to a
crawling start m January.
The Mmnesota-Wisconsm Price
Series brought a meager three cent
increase over December
Manufacturing grade milk prices
were still 33 cents below the sup
port price after four months mto
the new marketing year. Monthly
average butter and cheese prices
were the lowest smee October and
even the butterfat differential
dropped tor the first time m 16
months.
Nothing was increasing
significantly except Commodity

in protein content, a little arith
metic with the costs of corn and
protein supplement in the ration
will demonstrate the costs of
feeding the lower protein hybrids
This cost may or may not be made
up by any differences in yield of
the two hybrids.
If a low protein hybrid outyields
a high one, the simplest way to
calculate the value (or cost) of the
protein difference may be to figure
the pounds of protein each
produced per acre and value the
difference by multiplying it by the
cost of a pound of protein

is no bed of roses
CLOSER TO HOME
You don’t have to look any
further than the Order 2 uniform
price for January to find the result
of all these factors striking very
close to home
That three cent increase in the
M-W price from $12.61 in
December to $l2 64 in January
gave you a Class II price m Order 2
of $l2 67—the same as December.
You did “enjoy” a ten-cent in
crease in the Class I price because
of a jump in the M-W between
October and November. However,
a 3.6 percent increase in Order 2
production wiped out the Class I
price increase. But a 1.2 percent
improvement in Class I sales
saved you from a drop in the blend
price.
You still finished the month with
a Class I utilization one percent
lower than December, but a blend
price increase of a “whopping”
two cents from $13.44 in December
to $13.46 for January milk.
