Graze Grass; Don't Bale It,
Specialist Advises Cattlemen
By David Bowser
PLANO, Texas Developing a pasture system that
provides forages for harvest by livestock on a year-round
basis can substantially reduce winter feeding costs in
areas where the practice is applicable, says Dr. Larry A.
Redmon, forage specialist with the Texas Agricultural
Extension Service in Overton.
That's one of the few ways stockmen can improve their
bottom line, contends the East Texas specialist.
Improving the bottom line of a livestock operation
requires increasing the value of sales or decreasing
inputs costs, Redmon notes, "And beef cattle
producers have little control over the selling price of
their product.
"Therefore, the second method of improving the
bottom line, reducing input costs, is usually the more
viable approach to improving the economic condition of
the production enterprise."
In Texas, winter feeding costs are greater than 20
percent of the overall annual cost of cow ownership, he
says. Although use of hay or supplemental feed can be
beneficial under certain conditions, most producers
depend too heavily on these items for winter feeding
programs.
Redmon recommends stockpiling grass in pastures and
letting cattle harvest it.
Using a mixture of warm and cool season grasses,
cattle can graze pastures 12 months a year, lowering the
costs of winter feeding.
The grasses will vary, he says, depending upon
location. What does well around San Antonio may not work
near Dallas or in the Texas Panhandle; he says grasses
must be selected that have a chance to survive in the
environment where they're planted.
"Don't plan to feed any hay," he says,
"but always have a plan to feed hay if you have
to."
Redmon says producers are dependent on warm season
perennial grasses in the south.
"That's okay to an extent," he says.
"Usually, if we get some rain and we add some
fertilizer, growing conditions are good. It's pretty hard
to go wrong. About the only way you can go wrong is to
have too many cattle on the place. That will vary each
year."
But cutting it and baling grass increases costs.
"Hay is expensive," Redmon says. "It
may be the most expensive way to winter a cow."
A 1000-pound round bale of bermuda grass will
conservatively cost about $32.50 to $35 for the producer
to roll.
"Take that investment and expand it to how much
it will take to feed a cow, and it is a really expensive
way to feed," Redmon says.
He says he knows people in Arkansas who had $44 tied
up in bales last year. Another man in East Texas figured
he had $75 invested in each bale.
"We need to reduce our dependence on equipment,
on sack feed, on things we have to purchase
off-farm," Redmon admonishes. "Anything you
purchase off the farm comes out of your pocket."
He was recently told that the fertilizer industry
plans to shut down 20 percent of its capacity to produce
nitrogen in the U.S. next year.
"What's that going to do to nitrogen
fertilizer?" he asks. "I can only guess. I'm
sure it won't be beneficial to the cow-calf
producer."
Ranchers have got to get to the point where they can
produce cattle at less cost.
"We can't do much about the price we're selling
them for," Redmon reiterates.
A producer who does a really good job of managing can
own a cow for about $250 a year as opposed to those who
are paying $500 or $600 a year.
"There's $300 that you could be recovering,"
he says. "We don't want to do anything to diminish
the value of our sales, but usually as managers we have
the biggest impact on reducing our input costs."
A lot of producers have a lot of equipment and cannot
justify owning any of it, he quips.
"We've got to try to become good grass managers
so we can feed these cattle as close to 12 months a year
as we can out of the pasture," Redmon says.
"It's much, much more efficient and less costly to
let the animal do the harvesting."
There is a difference in nutrient requirements for
different classes of beef cattle, he admits, and each
program has to be tailored to the class and type of
cattle being grazed.
"Our spring calving cattle have a lower
requirement than fall calving cattle or winter
stockers," Redmon says. "We'll probably use an
annual rye grass, not a rye-rye grass mix. It costs so
much money to get that rye in there that you really need
to have some cattle that can take advantage of that
additional nutrition in the fall and winter."
He suggests reserving rye-rye grass, wheat-rye grass,
or oat-rye grass mixtures for fall calvers.
"We'll probably limit graze those cows and let
the calves have creep access to it," Redmon says.
For spring calving cows, ranchers can have rye grass
that will produce a good level of forage from February
through March and into April and May.
"It provides a lot of grazing," he says.
"Good nutrition."
Redmon has developed a protocol with bermuda grass in
North and East Texas, but ranchers have to be careful. It
may not work if the producer starts too early.
"If you accumulate growth from May until frost,
the bermuda grass is not going to be very good at
all," he cautions. "There are a lot of negative
things that happen with the age of these warm season
perennial grasses."
With age, crude protein and total digestible nutrient
levels go down.
"We have to start later in the year," Redmon
says. "Bermuda grass has a really interesting way of
growing. In the late spring, early summer, it has its
highest peak of growth. That growth is going to be
highest in crude protein and digestible energy
levels."
There's a slump during the summer.
"We still grow grass, but the nutrient levels go
down," he says. "Heat has a lot of negative
effects on those grasses."
The summer slump is not too good, but as the nights
start getting a little longer and temperatures start
cooling down, there is more growth and the nutrient
levels rise.
"It's not going to be as high," Redmon says.
"We won't grow as much, but it's pretty good grass.
The nutrient content of that grass will be awfully
good."
He suggests starting to let the grass stockpile about
four to six weeks before the first frost.
"What we're trying to do is capture that last
little blush of growth, hold that and graze that in the
fall and winter," he says.
The pasture that will be stockpiled should be grazed
short initially.
"We want it to be short because we want to start
young and not capture an old, mature plant," Redmon
says. "We would like to capture a hay harvest out
there.
Pull the cattle out, he says, apply about 75 pounds of
nitrogen per acre and let the grass grow until it frosts.
Redmon warns, however, that his protocol is designed
around one certain class of cattle, mature spring calving
cows that are going into the fall in good condition.
"It's not for developing heifers," he
insists. "It's not for first-calf heifers. It's not
for stocker cattle. It's not for bulls. It's not for fall
calving cows. It's for spring calving cows because of
their nutrient requirement for this time of year."
All too often, Redmon warns, producers want to talk
about yield off their hay meadows.
"Yield is not where it's at," he says.
"If it's only four percent crude protein, it's not
going to provide very good nutrition. It has to be based
on the animal's requirement."
One of the keys is how the pasture is grazed.
"We can't just open the gate when it's time to go
in on the stockpiled Bermuda grass," Redmon says.
"What the cattle will do is go around and sample
everything in the pasture. They'll tromp and waste a lot
of it. We've gone to great lengths to produce this forage
for a certain time of year, so we don't want to waste any
of it."
Instead, Redmon suggests strip grazing or a rotational
grazing system.
"A hot wire, if you've got a nice rectangular
pasture, works real well," he says.
Redmon recommends giving the cattle a day or two days
worth of forage and letting them take 60 to 65 percent of
the grass in the pasture.
"It's pretty clean, but we're not forcing them to
get right down to the soil surface," he notes.
As the forage is used up, advance the wire.
"Hopefully, about Christmas or New Year's Day,
we've cleaned that pasture up and we're looking around
the corner at this rye grass some time in February,"
Redmon says.
Such a system can reduce hay feeding from 150 or 180
days a year down to maybe 45 or 60.
"We figure it is worth about $30 per cow per
winter for a 100-day grazing period," he says.
That will vary, he admits, depending upon the
situation.
He doesn't recommend grazing the stockpiled bermuda
grass into late January.
"I want to cut it off around Christmas or New
Year's Day," Redmon says.
In the studies he's done, Redmon says there is no
significant difference between cattle that are
supplemented and cattle grazing only bermuda grass.
"There was no significant difference in those
animals' performance," Redmon says. "There was
no significant difference in body condition, live weight
change, intake or anything else."
He says the numbers suggest that a little
supplementation is beneficial, but it doesn't appear to
be cost-effective.
There is an Arkansas study, Redmon says, where one
pasture was grazed and another was treated as a hay
meadow.
"In October, they put a set of cattle in both
these pastures and grazed those pastures," Redmon
says. "On their stockpiled bermuda grass, they
basically didn't get below about 12 percent crude protein
going into January."
The total digestible nutrient values were also
similar.
Stockpiling bermuda grass is not new, Redmon says. He
cites studies from Oklahoma, Texas and Arkansas.
"We've got a lot of anecdotal things from
producers who have done it for many years," he says.
"It's a very good concept that they like and have
used to reduce the amount of feeding costs associated
with a winter feeding program."
If a producer is going to use stockpiled grass, Redmon
warns that he will have to learn to ignore bawling
cattle.
"Don't even drive by for a day or two, because
they'll stand by the gate with sad, droopy eyes,"
Redmon says. "You'll feel sorry for them so you'll
back up with some cubes. But don't do that. These cattle
are not going to die. They will breed back. They will eat
that grass."
