Does rain hurt fresh cut hay?

Research at Iowa State University found that fresh-cut hay with less than 1 inch of rain took a few more hours to dry, but didn't suffer much, if any, quality or quantity loss. A light rain on nearly dry hay, though, caused significant losses.

What happens if cut hay gets rained on?

If hay has partially dried and become brittle, quality can especially be lost to leafy forage when rained on after being cut. The force of the rain shatters the leaves which are the highly digestible and high protein portion of the crop.

Can you leave hay in the rain?

Unfortunately, rain can damage hay in several ways. Rain leaches soluble nutrients and keeps the moisture level high, thus increasing the likelihood of decay and mold. Hay rained on during field drying of course damages legume hay more than grass hay and the drier the hay when rain occurs, the greater the damage.

What happens if it rains on hay?

Rained-on hay often has relatively high protein values compared to fiber content unless there's great leaf loss. Leaves contain a lot of the plant's protein. As soluble carbohydrates leach, structural fibers make up a greater percent of forage dry matter. The digestibility of rained-on hay can decline 6 to 40 percent.

Is it okay for hay bales to get wet?

If wet hay is baled while it is too wet, microbe populations will flourish and intensify the heating process. This results in hay that is lower in nutritive value and dry matter availability. Allowing cut hay to dry (or cure) will slow down the respiration process.

Dealing With Rained on Hay

How do you protect hay bales from rain?

Use net wrap or plastic twine spaced no more than 4 in. apart on round bales to maintain bale shape and provide a smooth surface that encourages water runoff.” Anderson recommends storing hay on elevated, well-drained spots that will prevent the bales from soaking up moisture from wet soil or standing water.

How long does it take for cut hay to dry?

It basically takes about three days of good weather to cure hay. This can be a challenge in late May or early June. A good strategy is to mow just before or right after a rain, because of the likelihood of good weather for the next few days.

How long can you leave cut hay before baling?

Subject: RE: How long does your hay lay to bale dry? Cut first thing in the morning, ted about 2-4 hours later, do nothing the next day, rake as soon as dew is off (-48 hours after cutting), let dry about 3 hours, and bale. Sometime takes an extra day to dry or occasionally a day less if perfect weather.

Can you wrap hay that has been rained on?

If rain damage often plagues your hay making, you might consider using plastic wrap this year. Try baling it tough, then wrapping it with stretch plastic wrap to keep water and air out while keeping nutrients in. Studies have shown excellent success wrapping bales containing 25% to 40% moisture.

Can horses eat hay that has been rained on?

Rained on hay is actually beneficial for horses prone to laminitis and other metabolic disorders because of its reduced carbohydrate content. Analyzing forage for nutrient content is recommended, but can be especially useful when determining the quality of rained on hay.

Can you leave hay outside?

If hay is to be stored outside, it is desirable to locate the storage site close to the feeding area because bales become more difficult to handle as they weather. It is easier to move them a greater distance when they are new and tightly wrapped. Well-drained upland storage sites are best.

How soon can you cut hay after a rain?

Cut it the day before a rain. Rain doesn't hurt the freshly cut hay really at all and when the weather clears the ground is much dryer than if you try to cut right after the rain.

Does raking hay help it dry?

The drier the hay is at raking, the greater the leaf loss. If possible, raking alfalfa at moistures between 30 - 40% is often a good compromise between low leaf loss and good drying. Leaf loss can be extremely high if raking at 20% moisture.

Why do they wrap hay in plastic?

The last few decades have brought increased interest in the use of plastic wrapped bales for forage. The advantages are clear: reduction in drying time, better leaf retention compared to dry hay, no storage structures needed, and reduction in weather risk.

How soon after cutting hay can you feed it to horses?

So how soon can you feed new hay? If the hay is cut and bailed in perfect conditions with less than 12% moisture in the bale, it should be safe to feed straight away. But due to how hard this is to get accurate; it is recommended to wait 2-8 weeks before feeding.

Can you feed hay straight off the field?

In perfect conditions — where the hay has been baled at less than 12% moisture and is very dry — it is safe to feed straight away, but this isn't often the case, as Tim Moxon of TM Agri Services Ltd explains: “The main reason for allowing a period of anywhere between two and eight weeks before feeding freshly made hay ...

How do I know if my hay is dry enough to bale?

Breaking stems in half or twisting them in a circular motion to see if the stems break cleanly will give farmers the go-ahead to bale. “If all the stems break and crack that's an indication that the hay is cured and then you can rely on the moisture test that you're getting from the probe,” Yaremcio said.

Can you cut and bale hay the same day?

In a trial at the University of Wisconsin Arlington Research Station (Figure 2) where alfalfa was put into a wide swath it reached 65 percent moisture in about eight hours and could be harvested for haylage the same day as cutting.

Is it okay to cut hay early in the morning?

With all of these factors in mind, it is best to cut hay when there is the greatest opportunity for successful drying, or early in the morning after the dew has dried off.

How do you store fresh cut hay?

Keep Hay Protected

This can be done by using appropriate cover and also making sure the hay is sufficiently protected from ground moisture. This can be done by placing the hay on a bed of gravel, using old tyres or using pallets. It is important that a waterproof layer is used when storing outside.

Does hay need to be covered?

Never leave stored hay bales out in the open or sitting directly on the ground. Losses can reach up to 40 percent when hay has no cover above or ventilation below. Always stack bales on pallets or wood planks that form a lattice.

How do you store chopped hay?

Hay stored inside will lose far less (around 5 percent of dry matter). If a loose stack is stored outside, place it on gravel, rock, or on poles to keep it off the ground (hay will wick up water and forage quality will decline). Cover the stack with a tarp and weigh down with poles, tires, etc.

How often should you tedder hay?

Initial tedding should be performed after a brief wilting period following a morning cutting while the hay is still moist (two to four hours). In very damp conditions, tedding may need to be done immediately after cutting. A second pass is usually done the next day, and the hay is raked and baled that afternoon.

Can you bale hay at night?

Baling at night is nice if your climate will allow. Then the leaves start to toughen up before the stems and the outside before the bottom. “We used to go to the field when the air felt right. That is above 50 percent relative humidity.

How tall should hay be before cutting?

According to Gelley, the general rule when mowing lawns is to remove one third of the total leaf area. For hay production of cool-season pastures, mow or graze before seedheads develop, and down to 3 to 5 inches. For warm season pastures, mow or graze down to 8 to 10 inches for proper regrowth.
