Quality pasture, some
grain can make milk
UNIVERSITY PARK - High
quality pasture, combine with
modest amounts of grain con
centrate, can support reasonable
milk yields from cows in
midlactation, according to Earl M.
Kesler, dairy scientist at Penn
State.
In recent experiments, Kesler
and associates found that milk
production differed only slightly
among cows grouped according to
amount of concentrates in the
rations. With good management,
high quality pasture in the studies
supplied a major portion of the
nutrients dairy cows usually get
from grain concentrates.
“Our findings should interest
dairy farmers depending on grain
concetrates for efficient milk
yield,” Kesler commented.
“Future need for grains and plant
proteins as human food - and in
creasing costs for energy - may
dictate that future dairy herds will
be fed less concentrates.”
The experiment divided 30 cows
into three groups based on in-

dividual cow needs for net energy
above maintenance for lactation.
The cows were grouped according
to milk yield, milk fat percentage,
and body weight prior to the
studies.
Concentrates in the three groups
were split among cows fed 33, 66,
and 100 percent of the
requirements for net energy for
milk production above main
tenance. Daily intake of grain
concentrates by the three groups
averaged 8, 17, and 25 pounds,
respectively. Refusal of con
centrate tended to increase with
supplementation.
The tests included 21 Holsteins
and three each of Jersey, Ayrshire,
and Brown Swiss - all having
produced more than one calf. The
cows grazed high quality orchard
grass and Kentucky blue grass for
140 days in mid-lactation. Average
milk yield for the three con
centrate groups was 42 pounds, 45
pounds, and 47 pounds.

Feed costs make up more than half the cost of producing milk.
Maybe you can’t do much about feed prices, but you can
increase feeding efficiency. With a Computrac feeding system,
you automatically adjust each cow’s feed ration to her specific
stage of lactation or adjust for the precise ration you want.
You not only save teed, you can actually increase
milk production by bringing each cow to maximum
production sooner and maintaining the peak longer

Canada’s highest proven active

all the herds visited is crossed to

increased about three pounds after
two to three days, presumably
from increased available forage
and selective grazing of quality
herbage. After that, with continued
grazing, milk yields declined
gradually until the animals were
changed again to a new plot. Milk
fat yields were similar for all
levels of grain concentrates.
Most of the cows lost weight in
the early part of the trial,
especially among the low-grain
group. In general, cows tended to
gain weight thereafter so they
averaged 57 pounds heavier at the
end of the trial than at the
beginning. No major weight gain
differences existed among
treatment groups.
Health problems were minimal
during the 140 day trial. There
were a few mastitis flareups and a
single case of grass tetany. The
latter was complicated by
development of a displaced
abomasum, which required
surgery.
