Study Sheds Light On
Contrary to the practice of many
calf managers, who increase the
amount of milk and feeding
frequency during extremely cold
weather, a recent trial at the
University of Minnesota showed
these increases are not needed if
calves are consuming a high
quality calf starter.
The study also showed no ad
vantage in dividing milk replacer
feedings from two into three times.
It doesn't mean milk isn’t
critically important. But certaml>
there’s no evidence for the need of
feeding the extra amount, ac
cording to test spokesmen.
John Ryan of Madison Silo Co. of
Pennsylvania, distributor of Poly
Dome Calf Hutches, brought the
study to the attention of Lancaster
Farming and pointed out how the
tests were conducted.
Calves in one group were fed
0.6% of birth weight in milk
replacer solids, twice daily until

weaning. Calves in the second
group were given the same amount
twice daily with the amount in
creased by 0.2% of body weight of
every 10° in temperature drop
below 30°F.
Calves in the third group also
received increased amounts of
replacer as temperatures dropped
fed in three equal feedings.
Starting on the fourth day, all
calves were offered starter on a
free choice basis. Starting at two
weeks, warm water was fed bet
ween milk replacer feedings.
On the coldest days, calves in the
second and third groups were
receiving almost twice as much
replacer as calves in group one.
Weight gains for all three groups
were similar, since calves fed less
milk replacer ate enough ad
ditional starter to make up the
difference.

Existing product lines such as
solid steel rod farrowing crates,
gestation stalls, and hog fencing
currently manufactured by Tri-

Other popular products such as
feed bins, augers, feeders, ven

supplied as usual.
According to Terry Weaver, who
will serve as general manager, few
changes will be noticed by Tn-
County’s customers after the
transition, since the business

Coid-Weather Calf Feeding, Housing
extra starter to calves during cold
weather- rather than feeding extra
replacer- is that starter is less
expensive.
The U of M researchers
recommend weaning four-week
old calves during extremely cold
weather only if they are consuming
at least 2 Ibs./day of starter at
weaning, then rapidly increase
consumption to 34 Ibs./day.
Calves fed cow’s milk should
receive 10 Ibs./day, twice a day,
based on winter hutch trials at
South Dakota State University.
Calves fed 10 Ibs./day in two
feedings gained 1.34 lbs./day at
SDSU. That compares to calves fed
8 lbs. to one feeding that gained .79
Ib./day.

Calves fed 8 lbs./day of replacer,
fortified with lb. of a fat-whey
powder, gained 1.28 lbs./day.
Five-week-old calves should be
consuming at least I*2 lbs./day of
starter when weaned during cold
weather.
The U of M trials also compared
two types of hutches: domed
fiberglass and 4xB wood, in a
location not well protected from
northwest winds.
Calves raised in the domed
hutches gained weight the most
rapidly, due to increased con
sumption of starter, say the
researchers. The location of the
starter pail may encourage the
consumption, since the calves pass
their noses over it frequently.

TAKE ADVANTAGE OF:
Also, calves in the domed hut
ches were “more active and
social” than calves in wood hut
ches, probably because the
fiberglass hutches tended to be
warmer and brighter on cold days;
say the researchers.
No calves died in the U of M
study, but two calves raised in
wood hutches were treated for
hypothermia and hypoglycemia.
But, had they not been treated and
moved to warm housing, they
probably would have died, note the
researchers.
Both of the sick calves had been
weaned from the high-milk diets
and were consuming below
average quantities of starter when
they became sick.
