WICHITA FALLS – Landowners and cattle operators who utilize wheat as
a dual-purpose grain and grazing crop
can improve their efficiency and profitability through integrated management,
according to a Texas A&M range
animal nutritionist.
Integrated management means managing all resources within a production system in concert with one another, rather than as separate entities, said Bill Pinchak, Texas Agricultural Experiment Station range animal nutritionist headquartered at Vernon. Pinchak presented an overview of management strategies for dual-purpose wheat production at a recent Stocker Cattle Conference here.
The one-day conference focused on forages, cattle health, risk management and marketing, weather, and beef quality assurance. More than 100 landowners, wheat producers and cattle operators attended this event, which was co-sponsored by Texas Cooperative Extension, the Texas Agricultural Experiment Station, Extension offices on the Rolling Plains, and several agribusinesses.
“To make integrated management work, we must know all of our production
costs and commodity values for all phases
of a dual-purpose wheat system, and then manage the system according
to economics, rather than according to tradition,” Pinchak said. “Our ultimate
goal is sustainable profitability.”
Grazing stocker cattle on forages such as winter wheat is a major enterprise on the Rolling Plains. In any given year, there are about 1.5 million head of stocker cattle turned out on wheat, native and improved pastures in the 25 counties that comprise the Rolling Plains. In 2000, this value-added enterprise contributed about $150 million in cash income to the Rolling Plains economy.
“In this area, dual-purpose wheat systems are typically low-input systems.
We try to spend as little as possible getting a wheat crop up, so we can
provide fall and spring forage (grazing) for beef calves,” Pinchak explained.
“Some operators
pull their calves off the forage in spring and let their wheat produce
a marketable grain crop, while others find it more profitable to simply
graze the wheat out.
“The ideal dual-purpose wheat production system includes earlier planting to produce more vegetative forage growth; grazing that forage to produce as many pounds of beef as possible; and then harvesting a marketable grain crop a few months after grazing ends.”
Producers who closely manage soil fertility; variety selection; seeding
rates and times; stocking rates; and cattle nutrition
are most likely to return a profit from dual-purpose wheat, he said.
“Dual-purpose wheat requires more nutrients to maximize its grazing and grain potential. Texas research has shown that deep-placed nitrogen and phosphorus produces more forage and higher grain yields than surface or broadcast applications of these nutrients,” Pinchak said. “We also see higher net returns in this scenario, compared to grazing or grain production systems alone.”
It is best to select wheat varieties with “balanced” forage and grain potential, because the decision to manage for dual-purpose production often isn’t made until after the crop is planted, he added.
Seeding rates and dates also affect the bottom-line profit potential of dual-purpose wheat.
“Increasing seeding rates from 30 pounds per acre, up to 60, 90 or even
180 pounds per acre will increase forage production, as long as the crop
is planted before mid-September. Later planting dates will produce less
forage and less
grain yield potential,” Pinchak added. “Once we get a crop up, we have
to manage animal gains and forage growth by adjusting stocking rates. How
many calves will our wheat support before gains or grain potential decline?”
Recommended fall and winter stocking rates range from 250 to 500 pounds of animal per acre, while spring stocking rates are usually 1½ to two times greater than fall rates, due to increased forage production. Optimum stocking rates for dual-purpose wheat typically ranges from 1.7 to two acres per head, he noted.
Research conducted at Texas A&M’s Agricultural Research and Extension
Center at Vernon indicates that overstocking can reduce grain yield potential
and have more impact on final net returns than increased beef yield when
cattle are “taken
in on the gain.”
“When we terminate grazing also affects final grain yield and net returns. Research indicates we should terminate grazing when our wheat produces its first hollow stem,” he added. “Grazing beyond the first hollow stem growth stage can reduce grain yield potential by as much as 1.25 bushels per day. Final net returns from a dual-purpose crop also decline if we continue grazing past the first hollow stem growth stage.”
It is not uncommon for stocker calves to gain 1½ to 2½ pounds per day on wheat pasture alone. Wheat provides a better base diet than whole corn for a 300-pound steer averaging two pounds of gain per day, even though a wheat diet is somewhat lacking in digestible energy.
“In order to maximize average daily gains on wheat pasture, we need
to provide a daily energy supplement. We also need
to feed them a high-calcium, low-phosphorus mineral containing zinc
and copper,” Pinchak said. “We can also stretch our wheat forage, and help
reduce bloat, by feeding a good quality hay. These supplements help us
meet the calves’ high nutrient requirements and maximize their potential
gain.”
“Integrated management also adds flexibility to our operation. Most
years, dual-purpose wheat will bring in higher
returns than grain or grazing alone, but we have to be flexible enough
to adjust our system for the possibility of higher
grain
or cattle prices.”
