I’ve always been a very curious fellow. I
think it was my curiosity that made me a writer as the poet Alastair
Reid wrote, “Only the curious have a tale worth telling.”
One
of the things I’ve always been curious about is what sense is it that
makes cows run to the feed truck? Can they smell the hay on the truck?
Cows do actually have a better sense of smell than humans and that’s
saying something because we all know that a cop can smell a donut five
miles away and my wife can smell Olive Garden’s Fettuccine Alfredo two
counties away.
Speaking of my wife, did you know that women can smell better than men?
I’ve
always wondered what makes cows so reluctant to enter a squeeze chute
and had always assumed they associated it with pain but I did some
research and found that it’s because cows can smell stress in another
cow’s urine and this is what makes them balk. I also discovered that
butterflies taste with their feet and turtles can breathe through their
butts.
In addition to the five senses
that humans have, cows have an extra sense. Using a Google satellite
scientists looked at the way cows were laying down and found out that
they invariably faced north or south along earth’s magnetic field lines.
This extra sense is called a sense of magnetic direction!
Being
a curious person I have lots of unanswered questions such as, when a
Holstein cow laughs does milk come out its nose? I also wonder if the
gene in buffalo that makes them paw through snow to get to the grass
couldn’t be inserted into a cow’s DNA. But the biggest question I have
is what makes cows run to the feed truck?
Why,
for example did cows run to the truck when it was full of hay but
didn’t run to the same truck when I drove up the dirt road to the house
with no hay? At first I thought that they could see the hay on the truck
because of their acute sense of sight. After all, vision is the
dominant sense in cattle, responsible for 50% of the knowledge they gain
from their senses. They have panoramic vision and their only blind spot
is directly behind them. That’s why you should never drive cattle from
directly behind them but should be off to one side or sweep back and
forth.
