COOKEVILLE, Tenn. (Jan. 24, 2007) — As winter temperatures fall,
hay feeding is typically on the rise among the Upper Cumberland’s
beef cattle farmers — but a Tennessee Tech University agriculture
professor advises them to develop practices to allow continued livestock
grazing for as long as possible.
“Not only do permanent pastures have beneficial effects on soil
and water conservation, but beef cattle producers will also profit more
when they establish forage programs that provide a year-round feed supply,”
said Sam Winfree, a professor in TTU’s School of Agriculture.
“An Ohio study found that, as the number of ‘hay days’
increases, the opportunity for beef cow herd profit decreases proportionally,”
he continued.
That’s because abundant forages will reduce the need for grain
and protein supplements and will reduce feed costs, while increasing the
farm carrying capacity.
“Grazing is an economical forage harvesting method when compared
to the cost of processing, storing and refeeding hay,” Winfree said.
He offers tips for 15 forage practices that will reduce beef cattle herds’
hay requirements.
“These practices actually will reduce feed costs, allow cow herd
expansion and promote better performance in all classes of cattle and
calves,” Winfree said.
• Maintain proper soil pH.
• Apply fertilizers (nitrogen, phosphorus, potassium, etc.) based
on soil tests.
• Renovate grass pastures to contain about 30 percent clover or
other hardy legumes.
• Rotate livestock to new pastures every 30 days, and even more
often in some instances.
• Harvest pasture clippings as hay.
• Harvest hay crops before full maturity — at early to mid-bloom
or while green.
• Use fall re-growth as ‘stockpiled’ forage. Apply fertilizer
by Aug. 15 and keep cattle off the pastures until December or January.
• Use small grain annuals on cropland for winter grazing. Establish
crops by Sept. 15 and graze cattle on the pastures in January, February
and March. Spring oats may be seeded on the same pastures in March and
grazed May and June.
• Use summer annuals, such as sorghum forages, for mid- to late-summer
grazing.
• Keep hay crops free from foreign materials, including weeds,
trash and dust.
• Store hay inside to prevent water damage and molding.
• Use temporary electric fencing to facilitate strip grazing and
regular rotation.
• Graze hayfields after the second cutting in late fall or early
winter. “Be careful not to overgraze into the plant crown because
overgrazing stunts re-growth and allows weeds to invade the stand,”
Winfree advises.
• Provide adequate shelter, shade and clean water for livestock.
• Provide access to free-choice, loose high quality minerals and
magnesium supplements from October through May or year-round.
“High quality salt-mineral mixes are fortified with stabilized
vitamins A, D and K, as well as essential trace minerals,” Winfree
said.
These high quality mineral mixes add nutritional value to forages, especially
when forage quality is marginal, he said.
