Feeding Horses in Cold
Weather

Winter is here, I think. It must be as it is January and therefore the
winter season. A mild winter to be sure as I haven’t even had to plow the
driveway yet. One would think that I would be celebrating. I’m not. I’ve
seen more horses shivering from the cold over the past two months than I
have in any of the past nine years since I’ve moved to Kingston.
Why? Horses have as much difficulty in acclimatising to such dramatic and
quick shifts in temperature that we have experienced thus far as we do.
Perhaps more. The wicked winds coming off Lake Ontario carry so much
dampness that they cut right through those winter coats and into the joints.
Shelters, good coats and blankets not withstanding, I’ve seen too many
horses around the county shivering when they shouldn’t be.
Why is this a topic for a feed column? Because yes, we can feed horses to
help them stay warm, and there are three ways to go about it.
Assuming the horse is carrying good weight to begin with, the number one
answer is to feed them a LOT of hay. The act of eating hay causes them to
burn calories, and burning calories gives off body heat. Let them stand out
there and chew all day. Have you noticed that the gluttons who go after
every single tiny shred of hay are never the ones to get cold? It’s not
because they are fat, it is because they are chewing hay. This is a simple
and cost effective way to keep our horses healthy and warm.
The next two suggestions are for the more fragile, delicate horses. The
non-gluttons. The fussy “this hay isn’t perfect” types. The “oh I can’t eat
another mouthful” types.
If it is necessary to put weight on, or to keep weight on, feeding them fat
is a good way to go about it because fat is easily available to the body for
burning. With the changes in climate that we have experienced over the past
three winters, and predictions for continued winters like this one, we have
to change our approach and make sure our horses are “well fleshed” going
into the winter, even our performance horses whom we wish to keep fit and
trim. The rapid changes in temperature and high humidity are hard on them,
particularly on the joints. It’s easier on them to wear off a little extra
weight in the spring than to put it back on them. Keeping them in doesn’t
always help because so many of the older buildings are easily infiltrated by
the damp.
And finally, keep their immune system healthy so that they can withstand the
weather changes with less stress. There are many feeds available with a good
vitamin/mineral balance for those horses that eat enough concentrate to make
their minimum daily requirement available to them. For the others, there is
a wide assortment of vitamin/mineral supplements to choose from. To make it
easier on your horse to access the supplements in such difficult weather,
you may choose to use a chelated form. Vitamins and minerals do not occur in
isolation in the real world. During the production of a supplement, they are
separated from the molecules that they are naturally attached to. In many
cases those molecules actually aid in making the vitamin/mineral
bio-available to the horse. Chelation is the process of re-attaching the
vitamin/mineral back to such a molecule, which is why the chelated form of a
supplement is more expensive. It is well worth the expense as it ensures
that what you are paying for actually gets to where you want it, namely into
the horse rather than out to the manure pile.
Good luck this winter. For myself, I’m praying for a little more snow cover
and a lot less wind.
