Rhubarb

Although it is a veggie and it does provide some minerals and vitamins, rhubarb isn’t actually a nutritious food.

Sure, it provides a decent amount of calcium and vitamin K1 in its stalks, however the calcium is in oxalate form which means it can’t be absorbed by your horse’s body. Actually, it can cause more harm than good, which we will discuss in the next section.

Vitamin K1 is essential to maintain the ability of horses’ blood to coagulate and clot properly. But, the quantity in rhubarb are very small compared to other foods such as broccoli, kale and beef liver. Even pork chops and chicken provide more vitamin K compared to rhubarb! And they’re likely far more appetizing for your horse!

With rhubarb, there is a big risk that your horse will get sick if he eat it. And considering the limited nutritional benefits of this veggie, I’d say it is not worth it at all. There’s of course far healthier and tastier snacks out there for them to enjoy!

Is Rhubarb Poisonous to Horses?

Rhubarb have mild to moderate toxicity levels to animals, including horses. This is because rhubarb includes calcium oxalate crystals which are an irritant to our equines. This substance can irritate your horse’s mouth and lead to pain and swelling, as well as negatively impacting the digestive system, kidneys and bladder.

The oxalate crystals bind together to form what is called the kidney stones or bladder stones. Calcium oxalate kidney stones and bladder stones are commonly found in horses. Avoiding oxalate-rich foods such as rhubarb and spinach in your horse’s diet will aid them to prevent this bad problem and if your steed has suffered from bladder or kidney stones in the past, they have to be on a special diet to prevent the problem from reoccurring.

In some cases, consuming a big amount of rhubarb or any other foods and plants that contain calcium oxalates can lead to kidney failure which can be fatal.

But, the stems of rhubarb have fewer crystals than the other parts of the plant. That’s why some horses can eat a bit of rhubarb stem and be fine. Meanwhile, the leaves include a lot of those pesky crystals and are poisonous to both people and horses.

If your horse eats rhubarb, they can become ill and may show the following symptoms:

  • Excess drooling
  • Changes in thirst or urination levels
  • Loss of appetite
  • Vomiting
  • Diarrhea
  • Lethargy
  • Weakness
  • Dilated pupils
  • Discolored or bloody urine
  • Ataxia
  • Tremors

In addition, It can irritate your horse’s insides and upset your horse’s skin too. If your equine rubs up against a rhubarb plant, especially if the plant is broken and leaking sap, the minuscule crystals can jab into their skin and lead to irritation and itching. If your steed has bounced through some rhubarb plants and seems uncomfortable and scratchy, it’s best to give them a gentle bath.

If you grow rhubarb in your garden, try to make sure it’s kept out of reach of your horse who may try munching the leaves like a personal salad buffet.
