Nutritional Content Of Lettuce

Lettuce doesn’t have a very high nutritional value to horses and therefore shouldn’t replace other vegetables in their normal diet altogether. However, all lettuce types contain some vitamins and minerals which do provide at least some nutritional value (even if it’s only a small amount).

All lettuce types are made almost completely of water. In iceberg lettuce, for example, the water content comes in at 96%. As for the other types of lettuce, almost all of them consist of over 90% water too.

In addition to the high water content, lettuce contains fibre and a range of vitamins that vary according to the type of lettuce you buy. Below is a list of the different types of lettuce and the vitamins found in each type:

  • Iceberg – Vitamin C and K
  • Romaine – Vitamin C and K
  • Little Gem – Vitamin A, B, and C
  • Oak leaf – Vitamin A, B, C, and D
  • Arugula – Vitamin A and K
  • Butterhead – Vitamin B, C, and K
  • Boston – Vitamin A, C, and K
  • Bibb – Vitamin A, C, and K
  • Radicchio – Vitamin K

The Health Benefits of Feeding Your Horse Lettuce

Although lettuce has very low nutritional value for your horse, it doesn’t mean there are no benefits at all. It can still contribute to a long, healthy life for your horse. Below are some of the reasons why lettuce is a good option to add to your horse’s diet.

Keeps them hydrated

When horses eat iceberg lettuce, for example, they will also be taking in that 96% water that the lettuce contains. The high water content that is in all lettuce is a great way to keep your horse hydrated in hot weather or during intense physical activities.

Improves eyesight

Lettuce leaves contain vitamin A. This vitamin is great for overall eye health and maintaining the proper functioning of a horse’s retina.

Improves overall health

In addition to eye health, all the vitamins that are found in lettuce can help with the maintenance of your horse’s overall health. For example, vitamins A and C can help improve your horse’s immune system while vitamin K is great for bone health.

Helps with digestion

Fibre is great for horses’ digestive systems. And since lettuce provides a source of fibre, it can be beneficial to their gut health if you add lettuce to your horse’s diet from time to time.

How To Incorporate Lettuce Into Your Horse’s Diet Safely

The best way to incorporate lettuce into your horse’s diet safely is to simply add it in as an additional snack.

Practising moderation when you feed lettuce to your horse will ensure they stay healthy.

Preparing the lettuce correctly

Lettuce is an easy treat to prepare for your horse. All you have to do is separate the leaves, remove any wilted leaves, and then wash all the leaves under running water. You can also dry them afterwards if you don’t think your horse will enjoy eating damp lettuce leaves.

Separating the leaves ensures that your horse won’t choke when trying to eat a whole head of lettuce, while also allowing you to clean the lettuce properly to remove any harmful pesticides.

Feeding horses lettuce

Once you’ve prepared the lettuce for your horse, all you have to do is feed it to them. You can do this either by placing a leaf on your hand or by mixing it in with your horse’s regular meals. Just don’t add too much or it’ll take away from the rest of their meal!

How Much Lettuce Can Horses Eat?

As we’ve mentioned above, just like any other treat that you feed to your horses, it needs to be done in moderation. If you feed your horse too much lettuce, they will lose their appetite and won’t eat enough other foods that are part of a horse’s normal diet (such as grass or hay).

This will mean they won’t get all the fibres or nutrients that are essential to their health.

Generally speaking, if you wish to add lettuce to your horse’s regular diet, you should only feed it 0.9 kilograms of lettuce per day.

Types Of Lettuce That Are Unsafe For Horses

While the type of lettuce itself won’t be harmful to your horse in any way, there may be chemicals on the lettuce which are dangerous for your horse’s health. These can include pesticides and other chemicals that were used to prevent pests and bacteria from eating or damaging the lettuce before it was sold.

As a horse owner, you’ll need to make sure the lettuce is safe to eat before you give it to your horse. Washing it thoroughly to remove all the chemicals is essential and will provide peace of mind when handing them this crunchy snack.
