How much should you feed a horse a day

The following situations may result when horses are fed two times per day: When a large amount of concentrate is fed before the roughage component of the diet, the horse may consume the grain readily and then have a reduced appetite for the hay. The horse may “pick” at the hay or waste the hay by mixing it in the bedding.

According to the Ontario Ministry of Agriculture, a full-grown horse should eat about 12 to 15 pounds ( 5.4 to 6.8 kg) of hay a day. 1 That is 1.5 percent to 3 percent of its body weight if it weighs about 1,000 pounds (450 kg)

Well for horse feeding I had no idea but when I did horse riding I found riding jackets are quite much essential  because of safety.

One important thing to remember when picking a shirt or top for riding is that it covers your arms and also allows for free movement. A regular long sleeved shirt is fine, as is a short sleeved t shirt, providing you are wearing something else on top. Picking a suitable coat or jacket for riding is less straightforward. Theoretically, any coat or jacket that keeps you warm and dry and does not flap about is fine, and lots of riders wear brands and styles of coats that were not designed specifically for riding. However, coats designed specially for riding do have a few advantages.
