Hay is far more nutritional than any other horse feed but it is usually avoided because it develops mold quickly and can not be stored for a prolonged time. As the unfavorable weather and storage conditions can easily contribute to the development of mold, it’s quite fair to ask “how can one tell if the hay has turned moldy?” Well, the mold is never hideous, it can be caught by it’s signs.
Fortunately, even a naive person can easily catch it happening and destroying the hale bale. In this article today, we would be discussing the common signs of mold development, it’s treatment and prevention. So, none of my readers has to keep a reserve to buy an extra bale of hay just because the previous one gets moldy. Let’s not beat about the bush and come to the point;
How to tell if the hay is moldy?
First of all, your concern is valid when you have to store hay for uninterrupted nutrients supply. You can mainly judge the moldy hay by the appearance and smell. There would be some other signs as well but the moldy smell would alarm you more than any other sign of mold.
All possible signs of moldy hay
When the mold starts spoiling the horse feed, it shows visible signs of it’s appearance. The signs are;
- Unusual color
- Excessive dust
- Dried-out appearance
- Excessive heat coming out from the center of the hay bale
- Presence of mold spores
When a fruit or vegetable gets moldy it starts to smell strange; moldy. The same is the case with hay, the hay once it has developed even a bit of mold, would not smell normal at all. To be able to judge the hay by it’s smell, you need to know how the fresh hay smells.
The fresh hay would have a sweet woody smell. Smelling fresh hay would also remind you of maple syrup as it also, at the same time, smells like it as well. Whereas the moldy hay would have an acrid or musty smell. Moreover, you can also call the hay moldy when it starts smelling dusty.
It’s hard for a naive person to judge the quality of hay by it’s smell even though he/she does have a nose to sniff. It is suggested to cut the bale from the center, try sniffing immediately(without even wasting a second) because if you allow it to remain open for a minute or two, you may never be able to judge it from the smell as the surrounding air dilutes the odor.
You can not judge the book by it’s cover but you can judge the hay by it’s color or appearance. Even before smelling the acrid or musty smell, the unusual color would explain you all. The fresh or rightly preserved hay would have bright green color whereas, the moldy hay may appear in pale yellow or brown color. So, we can say the color change is the biggest indicator of mold.
The moldy hay would not only have a dusty smell, but it’s also going to be bombarded with dust as well. According to Research, the good-quality or let’s say fresh hay can also be slightly dusty but the moldy hay would have enough amount of dust to be called dusty.
Hay, that can still be fed, would look and smell fresh. The bright green color and sweet fresh odor are the visible signs of good quality hay. The hay that gives a dried-out appearance usually indicates the presence of mold. So, be aware!
Excessive heat coming out from the center of a hay bale
The hay that gets moldy or starts developing mold releases excessive heat from the center. Usually, when the hay that is not ready to be baled is baled, the hay bale starts developing mold and producing heat. So, whenever you find excessive heat releasing from the center, even if you can not spot any mold spores, take it as a red signal.
Presence of mold spores
The presence of mold spores is the most authentic identification of moldy hay. The mold spores can be any color including grey, white, green, brown, purple, pink, yellow, red, orange. Besides the individual colors, the mold spores can appear in a combination of colors as well. The mold spores can easily be noticed but in a hay bale, you have to look thoroughly to spot these visible marks of identification.
The moldy hay would be pretty “obvious”, if it still can not be identified, one can look for these above-mentioned signs. It’s super important to bring fresh hay as the moldy hay can cause colic, respiratory issues, and in serious cases become a reason for the horse’s death. (Source)
So, be aware! The hay should be bright green, sweet in smell, soft and pliable to touch, and must have consistent temperature throughout hay bale.
