It is not the temperature hovering around freezing, nor the searching wind
that will find the pinhole in the latest Antarctic wear from Patagonia, nor the
incredible damp that makes your bones ache that induces the pall at the prospect
of a Kentucky winter. Once you warm up, the seasonal changes can doubtless be
considered invigorating (at least by the delusional).

The "winter blues" now
have a more formal name; Seasonal Affective Disorder (SAD). Each winter,
millions of people suffer from more or less the same symptoms. These include a
general feeling of malaise, a desire to sleep longer, an increased appetite for
carbohydrate foods (and concomitant weight gain), and often a lack of libido.


The onset of these symptoms appears to vary with latitude, beginning
earlier in the year in the North and lasting longer in St. Paul, Minnesota, than
Atlanta, Georgia. Often, people will go on vacation in the Caribbean and quickly
find respite from many or all of the symptoms, with relief persisting for a
while even after their return to darker climes. Just as interesting is that the
same environmental clues that produce depression in many people are responsible
for the seasonal anestrus patterns in mares. Both conditions are tied to the
stimulation of biological clocks residing in all animals, whose timing is set by
the length of the day.



Around the day

We are normally
only aware of our own biological clocks when their timing is disrupted. Wiley
Post (the famous aviator who was killed along with Will Rogers in a plane crash
in Alaska) was the first person to recognize the symptoms now known as jet lag.
Flying around the world in eight days in the early 1930s, Post recognized the
adverse effects time zone displacement had on his flying proficiency and
struggled to evade them. It has now been determined that the human body can
accommodate speeds of about 100 miles per hour across time zones. This is why
you do not suffer from "car lag" from cross-country automobile trips.



Just as there are 24-hour rhythms, there are biological cycles occurring
on monthly (lunar) intervals, as well as on an annual scale. It is this seasonal
calendar within man and horse that is affected by the waning days, and the long
cold nights that accompany them.



Pining and the pineal


Deep inside the brain of all animals is a small organ called the pineal
gland. In humans, it is the size of a small pea and shaped like a pine cone
(hence its name). Also called the "third eye" (because of its nerve connection
to the other two), early anatomists were at a loss to describe a function for
the pineal. Rene Descartes believed it to be the seat of the soul, since it was
the only structure in the skull not directly connected to the brain. Early in
this century, scientists had concluded that it was a vestigial organ like the
appendix and no longer had a function in the body.

Then some industrious
researchers removed the pineal glands of 200,000 cattle, ground them up, and
squirted the juice on tadpoles to see what would happen. (I am not making this
up.) The tadpoles' skin lightened, so they called the pineal hormone
"melatonin."

Naturally, it is unlikely that all mammals produce hormones
just to lighten the complexions of self-conscious amphibians. Further study
determined that the melatonin was produced by the pineal in direct proportion to
the amount of darkness the animal perceived in a day. The longer the "night,"
the more melatonin was produced. It appeared that melatonin had an inhibitory
effect on hormone production by the pituitary and hippocampus.FPC sub-rolled

activity. The exact way melatonin works is unclear, but when an animal has
extended high levels of it in the blood, it will undergo shrinkage and reduced
function of the ovaries or testes. In effect, melatonin suppresses sexual
activity and receptiveness in animals.



Not tonight, honey

individual (at least as far as the species as a whole is concerned), what,the

the significance of suppressing sexual activity? Natural wisdom dictates that
you should not have young if you cannot feed them (a verity no longer understood
by many people). Periods of darkness are associated with winter, which is
obviously a period of reduced feed stores and harsh environmental conditions.
Other factors, such as food intake and temperature, also help establish the
biological clock. These zietgebers ("time givers") are useful to some extent,
but are subject to considerable variation from year to year. However, barring
cataclysm, daylight remains constant from year to year.

The need to
limit breeding to a specific period of time is particularly important for a
large animal such as the horse, which has a long gestation period. Eleven months
after conception a mare will foal, so timing the onset of the first season's
estrus to the lengthening days of spring will find the foals arriving at a time
when pasture is becoming more plentiful.
