UNIVERSITY PARK (Centre
Co.) As summer brings longer
days and higher temperatures,
dairy producers should adjust herd
feeding practices to ease the ef
fects of heat stress on feed intake,
according to an expert in Penn
State’s College of Agricultural
Sciences.
“Cows begin to eat less when
temperatures rise above 80 de
grees Fahrenheit,” said Virginia
Ishler, extension assistant in dairy
and animal science. “During the
summer, producers can keep feed
intake higher by maximizing cow
comfort.”
Helping cows stay cool will
help them maintain their appetite.
“Keep cows inside during the day
if it is cooler for them. Make sure
they have adequate shade over
feeding areas and while out on
pasture.”
As temperatures rise, ventila
tion in animal facilities becomes
more important “Make sure that
all bam fans ate working proper
ly,” Ishler said. “Keep air moving
through holding areas. If feasible,

reduce the number of cows enter
ing a holding area at one time.”
Providing the majority of the
ration during cooler times of the
day will ensure that your cows
have feed when they’re most like
ly to eat. “For example, feed be
tween 4 and 6 a.m. and 9 to 11
p.m.,” Ishler said.
High-moisture ingredients such
as com silage, hay-crop forage
and high-moisture grains will heat
if left sitting around during the
day.
“Feeding ensiled items more
frequently will prevent this and
help your herd maintain feed in
take."
Prepare total mixed rations
(TMRs) immediately before feed
ing.
“Don’t keep mixed feed in the
mixer wagon during the day,” Ish
ler said. “This will shorten the
bunk life of the TMR. The same
concept holds true for high-mois
ture grains, which should not sit in
a feed cart for more than one or
two hours.”

Feed For The Heat
To compensate for lower feed
intakes, boost the energy and nu
trient density of the ration per unit
of dry matter consumed.
“You can do this by increasing
concentrate dry matter in the ra
tion,” Ishler said. “But keep
enough effective fiber in the ration
to promote normal rumen func
tion.”
Cows may tolerate lower levels
of forage neutral detergent fiber
.80 to .90 percent of body
weight far brief periods, but
don’t let forage dry matter intake
fall below I.S percent of body
weight. Offering aftermath cut
tings of hay or hay-crop forages
and whole-plant com silage also
helps to optimize feed intake in
hot weather.
Adding supplemental fat can in
crease the energy density of the ra
tion.
‘The total dietary Cat content in
the ration dry matter should not
exceed 5 percent when oilseed in
gredients ate fed,” said Ishler.
“Rumen-protected or rumen-in
ert fat sources can provide addi-

tional energy, resulting in a die
tary fat content of 6 to 7 percent.
But cost-effectiveness depends on
the level of milk production, the
herd’s average stage of lactation
and the body condition of the
cows.”
Maintaining proper protein ra
tios during the summer also is im
portant. “Rumen undegradable
protein should make up 36 to 39
percent of the total crude protein
for cows in early lactation,” she
said. “Soluble protein should con
stitute 30 to 34 percent of the total
crude protein.”
Boosting levels of certain min
erals will help milk cows com pen-

sate for higher nutrient losses dur
ing hot, humid weather.
“On a dry matter basis, potas
sium should range between 1.4
and I.S percent of the ration,” Ish
ler said. “Sodium can make up .45
to .55 percent, magnesium .30 to
.35 percent and salt .SO percent of
the ration. Chlorine should range
between .25 and .30 percent of the
ration dry matter.”
The bottom line for managing
dairy cattle during summer is to
keep them comfortable, Ishler
said.
‘Take steps to keep cows pro
ductive by reducing heat stress
and making any necessary dietary
adjustments.”
