6 Signs of Quality Hay

6 Signs of Quality HayForage makes up between 50 to 90 percent of a horse’s diet. Much of the forage part of the diet comes in the form of hay. Because it’s such a big part of the ration, a good quality hay can help keep a horse healthy, while a poor quality hay can be detrimental. This is why we put a big emphasis on the quality of hay we feed.

The most important factor when determining hay quality is the nutritional value of the hay. Young, immature plants contain more nutrients than older, stemmier plants. Though after hay is harvested, the level of horse hay quality goes beyond the age of the plant at harvest.

When selecting your horse’s forage, keep these six signs of good quality hay in mind and how they compare to cubed hay:

1. High leaf-to-stem ratio 
Look for more flat leaves in the hay and fewer round stems; this indicates the plant was less mature when cut. More leaves typically mean higher digestibility and nutrient content for your horse.  This is more challenging to see in cubed hay.

2. Small diameter stems
Stems smaller in diameter or finer are also indicators of higher quality horse hay. Small stems mean the plant was less mature when cut. To test stem size, grab a handful of hay and give it a squeeze. Good quality hay is soft and pliable, and feels good in your hand. If it feels like you’re squeezing a handful of sticks, it is not a good choice of hay to feed your horse.

In cubed hay you can break open the cube. If you find large, stemmy pieces that may be indicative of poor quality hay.

3. Few seed heads or blooms
No matter the species of plant, hay with little to no seed heads or blooms indicates a younger, early maturity plant, and thus a higher quality hay. For example, timothy hay should be cut in the pre-bloom or early-bloom stage when you see little to no seed heads; and alfalfa should be cut when you see few to no blooms.

You shouldn’t see seed heads or blooms in your cubed hay.

4. Fresh smell and appearance
We love the smell of fresh hay. The same is true for your horse. Good quality hay should have a fresh cut smell and appearance. Avoid musty, moldy or off-setting smelling hay, because it can reduce palatability and indicate poor quality.

5. Cleanliness
Hay should be primarily made up of the harvested forages. Look for a clean forage with little to no dust. Even if the majority of the hay is high quality, hays containing dirt, mold, weeds, trash or other foreign materials indicate poorer quality hay and may be unfit to feed to horses.

Make sure your cubes are bright colored. Avoid musty, grey, and old cubes.

6. Hay Color
Good quality hay should be bright green in color with little fading. A bleached, yellow, brown or black color may indicate aged hay, mold or poor storage conditions. Storage condition and age have a significant effect on vitamin content of hays. Many vitamins, such as vitamins A and E, are not stable over time and lose biological activity. After approximately six months, almost all vitamin A and E activity levels are lost. The nutritional value of hay is compromised with increased exposure to heat, sunlight and rain, which speed up this process.

So how does this translate into cubes? Exactly the same. Look for bright color cubes with little fading.

When good quality hay for your horse is scarce or too costly, you may need to compensate for poorer quality hay. You can do this by supplementing with a quality balanced horse feed. Hay balancers help provide the missing essential nutrients the horse requires in the diet.
