What's up, doc?
Just like Bugs Bunny, many horses love carrots. Luckily carrots are very nutritious and make a great treat.
The one thing carrots are famous for is improving sight. This theory got started during World War II. Britain's Royal Air Force pilots supposedly ate large amounts of carrots. It was said this diet allowed them to see German bombers. But, the truth was the British had a new radar system. The rumor about the carrots was spread to protect the secrecy of the new detection system and explain why the British pilots were suddenly so successful at detecting the German bombers.
Despite this early rumor about carrots improving the eyesight of British pilots, they do contain large amounts of beta-carotene, so the story was somewhat based on fact. Beta-carotene is a precursor to vitamin A, which means the body converts it to vitamin A during digestion.
Vitamin A is needed for healthy eyes, mucus membranes, normal bone growth, healthy skin and hair. Horses get most of their needed vitamin A from fresh pasture and top quality alfalfa hay. Grass hay does not contain enough vitamin A to maintain normal levels throughout the winter. Commercial grains are fortified with vitamin A (manufacturers add it to the ration).
Carrots will not improve eyesight of a horse that is not deficient in vitamin A. The National Research Council's (1989) recommendations state a horse, at maintenance activity level, requires 30 I.U. (international units) of vitamin A per each kilogram (2.2 pounds) of body weight per day. This means a 1,000 pound horse requires around 13,635 I.U.'s of vitamin A each day. One pound of carrots contains 30,000 I.U.'s of vitamin A. The NRC has determined the upper safe limit of vitamin A for a 1,100-pound horse is 80,000 I.U.'s per day.
Vitamin A can be toxic if over-supplemented. Vitamin A is a fat soluble vitamin and is not flushed out of the system. The natural beta-carotene found in alfalfa hay, pasture and carrots has not been found to be toxic. The use of commercial supplements that contain vitamin A must be monitored to insure over-supplementation does not occur.
Carrots are high in sugar. It is recommended horses with Cushing's syndrome, insulin resistance or equine polysaccharide storage myopathy (EPSM) avoid being fed large amounts of carrots…or any other treat containing high levels of soluble carbohydrates (sugar).
Be careful when feeding carrots so choke is not caused. Slicing the carrots into long thin slivers will prevent a large chunk from becoming lodged in the esophagus of the horse.
There have been a few isolated cases of horses acquiring a slight change of coat color when being fed large amounts of carrots…people who over-indulge in carrots can also acquire an orange tint. Once the carrot consumption is decreased the color will revert to the natural shade.
As always, when introducing a new feed to a horse, make the addition gradually and over a period of time. The microbes within the digestive system must be allowed to adjust to the new feed. A half of a carrot sliced thin twice a day is a good start. Then gradually work up to several carrots over a period of two weeks.
So, if you have a 1,000-pound rabbit in your barn that likes carrots, don't worry…they are good for him - and you.
