Many things you do to take care of your
horse will depend on knowing its weight (how much food or medicine it gets, how
much grain or space it needs).
Since asking your horse to stand on your
bathroom scale would be tricky, here is a math formula to estimate a horses’
Measure the girth (the measurement from the
withers) -remember your horse parts?- down behind the front leg, under the
chest, and back up to the withers) in inches.
Multiply that number times itself. Then
measure the body length (from the point of the shoulder to the point of the
buttocks). Multiply the two numbers
together, and divide by 330.
Here is an example (Look
at your 4-H manual for more information on this if you need help):
Girth: 74.8 inches
Body length: 63 inches
74.8 X 74.8 X 63/330 =
You’ve heard that there is a farmer out
at Hay Meadows with some good hay for sale at 65 lbs per bale.
You know your horse needs about 20 lbs of hay per day. How much hay
should you buy to feed your horse for a year?
# of days to feed hay X 20 lbs per day
divided by pounds of weight per bale = the number of bales needed.
Each bale costs $6.00.
How much will it cost you to buy hay for the year?
# of bales X 6.00 =
Your horse will be doing all kinds of work:
trail rides, search and rescue, rounding up cattle.
Since he’s going to need some grain (a mix of oats and corn), let’s
find out how much to feed him at different times. Use the formulas for feeding
grain in your pamphlet.
Light work – 1˝ lbs of grain per hour of
Medium work – 2 lbs of grain per hour of
Hard work – 2˝ lbs of grain per hour of
You went for a two-hour trail ride today
(light work). How many pounds of
grain should you feed?
You went on a search and rescue mission for
10 hours today (pretty hard work). How
many pounds should you feed?
You took a group of hunters on a guided
hunt for the weekend. Your horse
worked twice a day for 4 hours at a time. How
many pounds of grain should you feed?
Congratulations! Your horse has great
hooves! To keep them that way, a
farrier should trim your horses’ hooves at least every two months.
How much will that cost you per year?
Farrier cost X visits per year =
