Feeding 2002 Hay
This issue will focus on one of my favourites – what to expect from the hay
crop of 2002. As horse people we have all been well trained in what to look
for in good hay. Emphasis is on the looking (green as opposed to black) and
smelling (sweet as opposed to dank and disgusting). We know that leafy as
opposed to stalky hay is preferred as there is better nutrition to be found
in the leaves. We know that unless we are in the breeding business, grass
hay (mostly Timothy) is preferred to legumes as alfalfa and clover have to
be fed sparingly due to their high protein content.
So what is it that a visual inspection doesn’t tell us? The impact that the
weather throughout the growing season has had on the current hay crop. None
of us can deny that the wet spring followed by a dry summer has given us a
very high yield of hay. The hay was ready to come in early because the
spring rain had made it grow quickly and the ensuing drought had the fields
dry enough to support the tractors and haybines early in June. Furthermore
the continuing dry weather ensured that the hay dried well in the fields.
Not much dust and mold to be seen or smelled in those bales. Should be a
great year for high hay quality as well as great yield because we continued
to hay from May to September.
Unfortunately, hay is not always as good as it looks. Two issues have become
apparent this year. Hay sampling has shown higher mold values than anyone
would have predicted in very nice-looking bales, a matter easily taken care
of by watering the hay. The second issue is the digestible vs non-digestible
content of the hay. Because of the growing conditions lignin values are
tending to be high. Lignin is one of several not-so-digestible components of
hay and is used as a marker to determine the value of a hay crop to the
horse. At a certain point the horse will simply refuse to eat it.
How they know by sniffing or looking, I have no idea. I do know that nothing
is more frustrating than coming into the barn in the morning and finding a
mound of perfectly good-looking hay and a cranky horse. The easy assumption
is that he isn’t hungry, is being overly picky just to annoy us, or help –
is he in trouble? It is important to know that he just doesn’t like his
broccoli cold. The solution is to feed him a lot more hay than you think you
have to in order to ensure that he gets his 1-2.5% of body weight
requirement in hay into him and put up with throwing what he doesn’t eat out
to the cows, bless them. Or pay a premium for fantastic hay that some
amazing farmer managed to grow despite the weather.
Many people will reach for the bag of roughage feed in the many forms that
it comes in. We have to remember that it is made from the same hay crop that
your hay came from, and may be no more digestible than your nearest bale.
How can you tell? Your local feed store, veterinarian and OMAFRA office are
all able to sample and test your hay for lignin values. Knowing your
strategy before you get into the winter heavy hay feeding months is a wise
precaution.
