Can Guinea Pigs Eat Horse Hay?

It’s a known fact that guinea pigs are vegetarians and herbivores. This means they consume things that usually grow from the ground, but some of these foods are not good for them – even when they are natural., So, keeping a guinea pig is not very simple. Yes, their nutrition seems easy to handle; fruits and veggies, and all other growing things, right? Not exactly, there are other types of foods which are not fruit or veggie but they are still good food for the cavies. So, today we will talk a bit about horse hay as food for the guinea pigs.

Can guinea pigs eat horse hay? Yes, guinea pigs can eat horse hay. The most important thing when you purchase hay is that it needs to be mold-free, and fresh. Also, it would be even better if the hay you buy is not mixed with some various grasses or weeds. When owners purchase large bales of hay, it is possible that the hay won’t be as fresh as it is the case with smaller bales of hay, so keep this in mind. It is always recommendable to see the ingredients of the package when you buy the hay – it should be hay only, and not mixed with alfalfa (due to the high amount of calcium in this).

The cavies can and should eat hay, it is not harmful to them. In fact, they should eat as much as 75% hay overall compared to the other foods they eat. In other words, 75% of their diet should be hay.

Health Benefits of Guinea Pigs Eating Horse Hay

The benefits of the horse hay for the cavy are all great and all equally important. One of them is the fiber content in the hay. When cavies get enough fiber, their digestive system works perfectly. Deficit or excess of fiber is not good for them, but they themselves know how much hay they need (lots of it on a daily basis!), so they take care of this themselves. With enough hay every day, limitless amounts, the cavy will have healthy digestion.

Also, another benefit is oral health. The munching of hay literally prevents the cavy’s teeth to become worn down or overgrown – so hay is not just a healthy and tasty for them overall, but hay is good for their teeth too!

Nutrition Facts of Horse Hay

There are many different types of hay out there. One of them is alfalfa hay. This one is also named “Lucerne” (a very popular flower). Alfalfa hay is abundant in calcium, so it’s beneficial just for young cavies. Also, alfalfa hay is found almost everywhere worldwide.

Then, there is the red clover hay. This one can be found in Europe, north-east Asia, as well as western Asia and it is also abundant in calcium.

Another hay type is the orchard grass. This one doesn’t have that much calcium and phosphorus so it is somewhat acceptable for guinea pigs to eat it, but not very often, and moderately quantities.

The most popular is timothy hay. Timothy hay proved to be the best choice of hay for guinea pigs. It can be found in Europe and the Mediterranean region as well. When choosing timothy hay it needs to be green, without a dusty or stalky appearance.

Also, we need to mention the bermuda grass (Scutch grass). This one looks greyish-green, has some rough edges and it is quite short. It also has a low amount of calcium and phosphorus, so it’s relatively safe to eat, compared to other types.

Hay, in general, is a great source of vitamins, minerals, proteins, and even fiber. There is a difference between the two main types or most used types of hay; the grass hay is rich with fibers and it also contains some dry matter, but the alfalfa has lots of calcium, proteins, and vitamins. So, when someone tries to package the hay and sell it for guinea pigs, it’s understandable why alfalfa mixes are most commonly used – and mistakenly, people want to feed cavies with as many nutrients as they can. But, in this case, calcium from alfalfa is not needed for a grownup guinea pig – choose plain hay only.

There are different nutritional values for different types of hay. So, here are a few types listed, with caloric values per one pound:

  • Orchard grass hay – 872 cal.
  • Timothy hay – 804 cal.
  • Alfalfa hay – 977 cal.
  • Alfalfa pellets – 970 cal.

So, generally, the timothy hay is much better and more recommended than the alfalfa hay. The Timothy hay has less calcium and phosphorus, so it’s more suitable for all grown up guinea pigs.

And, if you want to choose other types of hay, these are good as well: Wheaten, Oaten, Paddock, Pasture, Ryegrass or Meadow hay too. The alfalfa and the clover should be avoided when it comes to guinea pig diet.

Risks to Consider When Feeding Horse Hay to Guinea Pigs

One of the risks with hay is the calcium and the amount of phosphorus. Of course, this goes mainly for the different types of hay, so depending on which one you buy – you should see consider the calcium amounts in it.

For example, the risk of feeding your cavy alfalfa hay is the high amount of calcium in it, so the cavy might get excess calcium deposits in the body. The calcium deposits can create bladder or in kidneys stones. Of course, if this is not treated in time, your guinea pig can end up with kidney failure!

Above, we have mentioned that there could be mold, dust, or other weeds in the hay. These things can severely damage the guinea pig, and such foreign things can cause respiratory problems for your guinea pig.
