If you think about it, they are large... Horses usually spend 14 hours a day grazing and eat A LOT.
Because they are strong and were designed that way
Well, its not so much that flies like the horses, its mostly the manure the horses leave.
Correct! A horses diet is rationed on the weight and size of the horse and how much daily exercise it does. Correct! A horses diet is rationed on the weight and size of the horse and how much daily exercise it does.
Horses (all horses) need 1.5%-3% of their body weight in forage per day as a base for their diets.
All Arabian horses have different weight, it does not matter about the breed. All horses have a different weight.
Im not sure but I think they like horses so much because it probably seemed to them that horses were alike to there culture!
Light horses can weight between 900 and 1400 pounds typically.
none they are for shows with handling
Well this would depend on the horses weight, as you should feed a horse based on body weight. So from your question I'll assume you mean 100 average sized horses so say 1200 pounds each, and that they are not doing any kind of work. So feeding a 1200 pound horse at an average of 2.5% of it's own body weight in hay, that would be 30 pounds of hay per horse. So 30 x 100 = 3,000 pounds of hay in one day.
I have seen so many questions like this and I must stress JUST BECAUSE THEY ARE THE SAME GENDER DOES NOT MEAN THEY ARE THE SAME WEIGHT! There are many different breeds of horses and some are MUCH taller then others. Would it make sense for a male human that is 5'4'' to weigh the same as a male human that is 6' NO!!!!!!!!!!
they have lots of flavor and healthiness in them so they attract horses
they don't have to be they are normally because less weight makes them go faster
