Hay Test Can Lead to More Efficient Feeding During Drought

Nutritive value is key to overall efficiency for beef cattle intake.

COLLEGE STATION, TEXAS (Oct. 20, 2011) — An inexpensive hay test can offer the best guidance as to how much supplemental feed is required for a beef cattle herd, and at the same time, save ranchers money, according to a Texas AgriLife Research scientist.


Considering the historic drought conditions that prevail across Texas, Tryon Wickersham, an AgriLife Research animal nutritionist, said forage testing is even more important for cattle producers watching the bottom line.


“With feeding programs being one of the most costly components of a cattle operation, every penny must be spent precisely, especially during these historic

drought conditions,” Wickersham said.


A hay test can cost $50 or less, and Wickersham said many ranchers may be feeding more hay or supplement than they have to or the wrong type of supplement.


A hay test will reduce the likelihood of both situations, he said, noting that

his recent research evaluated both variability in crude protein content and

digestibility with Bermudagrass hays.


“The outcomes were a (bit) more variable than native grasses,” he said.

“The outcomes depend on how much it has been fertilized and how mature the

Bermudagrass is.”


The study found that increased Bermudagrass utilization (intake and digestion)

with increasing nutritive value supports the recommendation of feeding

high-quality hay.


“However, there must be a balance between optimizing quality, quantity and

cost when producing hay,” Wickersham said. “These observations from the

studies clearly demonstrate the value of purchasing and marketing hay based on

nutritive value.”


Wickersham said a hay test can provide information on both crude protein content

and forage digestibility, if requested.


He advised ranchers to test their hay to get a more accurate gauge as to how

much supplement and what type of supplement to purchase and feed.


“Producers with higher quality hay may want to look at lower priced energy

supplements and reducing hay availability as a means of conserving forage,

reducing cost and maintaining body condition score," Wickersham said. "With the

current hay prices, you don’t want to give them unlimited access to hay. You

don’t want to put 10 bales out and come back 10 days later.”


In contrast, Wickersham indicated that producers with lower-quality hay will

need to pay attention to providing a supplement with adequate levels of both

energy and protein. In either case, a producer can make a much better decision

with information on hay nutritive value.


Additionally, bulk feeds can be an efficient method of feeding cow herds, but

you have to have infrastructure in place to do this or evaluate the cost of

adding this capacity, Wickersham said.


"Drought demands that producers find the cheapest source of energy they can

realistically handle and safely feed," he said. "Unfortunately, cheap is more

than it used to be."
