Dennis Pearson is serious about his hay, with good reason. "Thirty percent of our income comes from hay sales," says the Warrenton, Virginia, producer. Equally as important, if not more so, it helps fuel his 80-cow purebred Angus herd. He tests the rolls he feeds, as well as the small square bales he sells to customers for their horses.
Pearson's county agent, Tim Mize, is all for that kind of detailed approach to hay management. "All hay is not the same. It is like EPDs (expected progeny differences). You can't tell by looking at a bull what his EPDs are. And if you just look at hay, it won't tell you where it is in quality and how you need to feed it."
Texas A&M Extension beef specialist Jason Banta agrees. "If you test, you know which cutting or lot to feed to which class of cattle."
For example, if cows are dry, assuming they weigh around 1,300 pounds, they can get by with 55% total digestible nutrients (TDN) and a little over 8.5% crude protein (CP). If they calved and are hitting peak lactation, that goes up to 61% TDN and 12.5% CP. Feed them all the same hay, and somebody is either getting short-changed or overfed. With a hay analysis in hand, however, you know who should get the better hay.
At Pearson's Soldiers' Hill Angus Farm, the orchard grass, fescue and bluegrass hay he grows run anywhere from 58% to 62% TDN and 8% to 14% CP. The highest-quality bales go to growing cattle, which include weaned calves, replacement heifers and young bulls. He supplements them lightly with grain, at less than 1% of their body weight per head, per day. Mid-quality hay goes to lactating fall-calving cows, so they'll be in good condition for rebreeding, which includes both artificial insemination (AI) and embryo transfer (ET). The lower-quality hay goes to the spring calving herd, which is dry during the winter when he typically feeds the most stored forage.
FORAGE TESTS NOT ALL ALIKE
Mize handles Pearson's forage tests, reporting back quality levels. Pearson takes the hay samples; Mize sends them to a commercial lab. Typically, he gets the near infrared reflectance spectroscopy (NIR) analysis done, rather than the more expensive wet chemistry analysis, which takes longer.
The basic analysis, which currently costs $18.50 a sample, gives dry matter, CP, adjusted crude protein, neutral detergent fiber (NDF) digestibility and mineral content. Estimated net energy for maintenance (NEM) and net energy for gain (NEG) are also included and are useful for growing animals, like stocker steers.
Mize says TDN is also in the report but is an estimated number rather than an exact measurement. "Producers are familiar with TDN, and it works well for beef cows."
If you're buying hay rather than putting up your own, Texas A&M's Banta says it shouldn't be a problem to get it tested before you buy.
"Most hay dealers are willing if you tell them you'll pay for it and share the results with them whether you buy it or not," he says.
WEIGHT AND DENSITY MATTER
Whether you're buying hay or growing your own, weight of the bales is another big variable that is best not left to guessing. Round bales are usually described by width times diameter. Density also plays into the equation and can make a big difference in actual cost of hay and/or how often you must feed it.
On Pearson's operation, it is moisture that makes the difference. His 4-by-5-foot dry bales usually weigh around 800 pounds a roll, while his wet wrapped hay (baleage) averages 1,600 pounds. Because of the variation in weight, even in dry hay, Banta recommends buying per ton, rather than per roll. If a 1,100-pound roll and an 880-pound roll are both priced at $45 a roll, you'll be paying $81.82 per ton for the heavier roll and $102.27 per ton for the lighter roll.
Whether his hay is for cash flow or cow feed, Pearson intends to continue to keep tabs on the key measurements.
"We put a lot of effort and time into our hay so we can sell it, but we want to provide our cattle with the best nutrition we can. It helps with conception rates, milk, gain and performance."
Mize agrees. "With a forage test, a hay producer can sell his hay based on actual nutrient value, and cattle producers also need to know the quality of their hay. If it is high-quality hay, they might be overfeeding and overspending. If it is poor quality, you could be underfeeding and losing production and pregnancy rates. All hay is not the same."
