When storms build on the horizon, Middleton, Idaho, hay producer Milton Osgood doesn’t like to gamble. After more than six years of using a hay preservative, he now treats nearly every cutting and calls the product less as an input and more as a risk tool.
“I look at it as being, if nothing else, an insurance policy for if you have weather turn against you,” Osgood says. “We’ve been able to save crops, get them up before the rains came in.”
For a producer without hay sheds and with plenty of weather risk, that “insurance” has become central to how he manages hay quality, buyer confidence and livestock performance.
Osgood says the original driver was simple: Too many times, the weather narrowed his baling window and left him pushing borderline moisture or watching quality decline under a storm.
“We baled hay what normally I would say you would not want to bale… but there was a big storm,” he recalls. “You would not have gotten it baled had we not had it on it.”
Instead of losing a cutting or watching it turn to lower‑value feed, the treated hay held up. That experience, repeated over multiple seasons, cemented his view of the product as weather insurance more than anything else.
“I look at the cost as being insurance for it,” he explains. “I haven’t had any of my buyers come back with problems or anything.”
As unpredictable weather compresses hay harvest windows across the country, growers are increasingly forced to choose between baling under less-than-ideal conditions or risking total crop loss. To help manage this high-stakes timing, producers can utilize Lallemand Animal Nutrition’s Magniva Hay — a natural inoculant designed to stabilize forage quality when the weather won’t cooperate.
Rapid shifts in moisture, delayed field access and limited drying time are raising the risk of heating, mold and dry matter loss, putting both forage quality and the value of every ton at risk. With tighter margins and rising input costs, protecting forage investment has become more critical than ever. Magniva Hay’s natural inoculant was designed to help growers manage these challenges and maintain more consistent forage quality from field to storage.
Producing high-quality hay requires balancing moisture and timing, often under unpredictable conditions. When hay is baled too wet or exposed to changing weather, the risk of spoilage, mold and nutrient loss increases, reducing both forage value and return on investment.
“Hay growers are managing more weather and harvest variability than ever,” says Megan Smith, Lallemand Animal Nutrition global forage technical project manager and hay solutions business developer. “Magniva Hay helps protect the nutritional value and consistency of hay cuttings during harvest, giving greater feed value and offers flexibility and confidence in how they feed the forage they work hard to produce.”
According to Smith, Magniva Hay supports a more controlled and stable preservation process, helping maintain forage quality during storage. It features a research-proven, hay-specific bacterial strain, Pediococcus pentosaceus NCIMB 12674, combined with an enzyme that enhances preservation in higher-moisture hay and supports nutrient retention after baling. By limiting undesirable microbial activity, it helps preserve dry matter and nutrients, protecting the investment already made in the forage and supporting more consistent forage quality.
Unlike traditional chemical preservatives, Magniva Hay is noncorrosive and safe for both equipment and handlers, while allowing baling at up to five percentage points higher moisture. This added flexibility allows growers to better manage narrow harvest windows, helping reduce weather-related delays, leaf loss, dust and heating risk, while preserving green color, aroma and nutrient density.
The Setup: 25‑Gallon Sprayer and Inline Baler
Osgood emphasizes that once the system is set up and calibrated, it’s straightforward to use.
“What I use is a 25‑gallon ATV sprayer that I’ve mounted a carrier right on the tractor,” he explains. “It sits right by the tractor, and then I can reach the controls and adjust pressure if I need to.”
He welded a fixture to mount the nozzle directly over the pickup on his inline baler. That positioning lets the product hit the forage just as it’s fed into the machine.
“It’s where the pickup on the baler is lifting the hay up into the machine,” he says. “Just as the alfalfa comes into the throat of the baler, the nozzle is right above, and it’s a wide‑angle nozzle, and it puts a fine mist onto the hay. Once you get rigged up like that, it’s not too bad. You just need to drive the right speed — calibrating for the amount of product to put on it.”
He’s part of a small group of neighbors who use similar systems. Some of them mount the sprayer directly on the baler and run control cables back to the tractor cab instead of a long hose.
Proof in the Barn: Livestock Like It
For Osgood, some of the strongest feedback has come from the folks and animals on the feeding end.
One sheep customer had high praise for the treated hay: “The fellow that used it for his sheep said that it was just like candy to them,” Osgood says. In fact, that customer ended up blending in some poorer‑quality hay so the ration wouldn’t be “too hot.”
Osgood notes no mold, good smell and animals cleaning it up reinforce for him that the preservative is doing its job.
