Baleage option for hay storage cuts dry time, speeds harvest, and livestock love it

Dreary, rainy summers increase interest in making baleage, or silage in a bag, says Rob Kallenbach, University of Missouri Extension forage specialist, because baleage reduces hay harvest time from three or more days to one day.

"You can usually find one clear day to harvest baleage, even in May," Kallenbach says.

With baleage, forage to be ensiled goes into a plastic bag at high moisture, up to 65%. In comparison, hay should be dried to 16% moisture before rolled into big, round bales. Hay baled wet can burn.

Moisture is required
The big danger in making baleage will be letting hay become too dry before wrapping. Forage needs moisture to ensile. Baleage can be made down to 40% moisture, but drier hay carries more oxygen into the wrapping.

For baleage, cut the forage and roll it into big bales, Kallenbach says. That's similar to making dry hay. Then the bales are tightly wrapped in plastic to seal out oxygen. Inside the oxygen-free package, the forage ferments as in silage-making. Ensiling converts sugars into lactic acid, which preserves forage quality.

"Compare it to pickling," Kallenbach says. "Cattle love baleage. They eat everything, with little waste."

Get a good seal
Skimping on plastic wrap and not getting a good stretch-wrap seal around the baleage creates problems. The wrapped bales must be airtight. If oxygen enters, the forage turns to mold.

"A quarter-size hole in the plastic results in a basketball-size spoiled area," Kallenbach said. "Puncture holes can be sealed with tape. That requires frequent checks of wrapped bales."

Big birds and rodents puncture the plastic. A bigger threat can be a pre-teen farm boy doing stunts around the bales, he discovered. Also, it's better to let weeds grow up around wrapped bales than mowing too close.

"If you see those long white objects that look like a giant caterpillar, that is baleage wrapped into a continuous row of bales," Kallenbach says.

Wrap it up
Making baleage requires a separate machine that takes the big bales delivered to it for a spiral wrap of overlapping plastic.

The 1-mil plastic sheeting, which comes in a roll, overlaps to provide at least a 4-mil-thick wrap. More wrapping may be needed if bales are to be sold and transported.

Some baleage can be made into individually wrapped packages. Farmers find the preferred method is continuous in-line wraps, Kallenbach says, which eliminates need for end wraps on bales.

A hold-back to baleage adoption has been the cost of wrapping machines. The more expensive continuous wrappers cost $28,000 to $30,000.

That cost opens a chance for entrepreneurs to custom-wrap bales. The operator wraps and supplies the plastic at a set fee per bale. Producers make bales and deliver them to the custom operator at the storage site.

Haylage advantages
An advantage of baleage is getting hay harvested early before seed heads set, when nutrient content is highest. Early harvest allows quality regrowth during the cool-season-grass spring growth period. More high-quality forage can be harvested after the first cutting.

Livestock benefit from improved feed quality, making more gains or milk.
