PROBLEMS WITH SHIPMENTS BY FOLLOWING THESE
1. If your shipment does

will be needing semen.
not valid if placed by email.
3. DO NOT OPEN
YOUR SEMEN CONTAINER until your veterinarian is
present and ready to inseminate.
4. It is best to
inseminate your mare as soon as possible after
receipt of semen shipment and then again within 24
hours. Cooled Semen is best used in 24 to 48 hours.
Semen loses its viability the longer it is stored
after collection. Calculation of the 24 to 48
hour window begins at the time of collection, NOT
the time your receive semen or inseminate your mare.
DO NOT WARM SEMEN, your mare provides the
best environment to warm the semen.
5. Use the entire
contents of one syringe. All shipments will
contain two (2) separate inseminations when
available. All requests for shipped semen will
be filled as received and are subject to
availability. If the second dose is not used,
discard the semen and return the container.

FROM THE STANDPOINT OF FERTILITY,
the ideal time
to breed mares in the Northern Hemisphere is from
May through August. Pregnancy lasts for about
335 to 342 days, but the length of gestation is
extremely variable. Normal foals have been
born after gestation periods as short as 305 days
and as long as 400 days.
is often not practical to wait until May to breed
mares because many breeds recognize January 1 as the
official birthday for all foals born in a calendar
year. This means, for example, that a foal born in
May after a June breeding the previous year is the
same age for showing purposes as one born in
January. In reality, the foal born in January
is almost one-half year older and will have a
decided advantage when showing even as a two- or
your foal is to be used for a purpose such as halter
showing, where its real age relative to its official
age is important, you should have your mare bred
early in the season. Since mares generally are not
ovulating in February, March and April, special
measures must be taken if you want to breed your
mare at this time!
TO GET YOUR MARE
READY FOR AN EARLY BREEDING:
most common approach to early breeding is to place
the mare under supplemental light starting in late
November (we use Thanksgiving as our starting point)
. Essentially, you must convince your mare that
spring has arrived by exposing her to artificially
increased day-length. Light can be
supplemented in the afternoon and evening to give a
total of 16 hours light each day if you don't want
to keep the lights on all day. We use a timer.
A dark period should not interrupt the transition
from daylight to supplemental light and the lighting
program should be consistently followed each day.
The light should be bright enough for you to read
the small print of a newspaper throughout the mare's
housing area. We use a 300 watt clear light bulb.
Most mares will begin ovulatory cycles after about
60 days of light supplementation and will be ready
to breed in February and March. The lighting should
be continued until your mare is confirmed pregnant.
Your veterinarian may recommend that a progesterone
product (ex: RegumateTM) be used in conjunction with
lights to avoid the pattern of long or irregular
estrus typical of the spring transition from the
anovulatory to ovulatory season.
estrous cycle lasts about 21 days.
However, the length of estrus itself
(the period of sexual receptivity) is
highly variable. Ovulation is more
closely linked to the end than to the
beginning of estrus.
POOR MANAGEMENT OF BREEDING IS THE SINGLE MOST
IMPORTANT CAUSE OF REPRODUCTIVE INEFFICIENCY IN THE
Most of the problems result from a failure to
appreciate either the seasonal nature of
reproduction in the horse, or the fact that mares
have a variable estrous cycle pattern even during
the ovulatory season. A thorough understanding of
basic breeding management and careful attention to
the details of a breeding program should maximize
your chances for the timely birth of a healthy foal.
The mare's estrous cycle, the period between one
ovulation and the next, is about 21 days long.
Estrus, the time of sexual receptivity, occupies
about seven days of the cycle. Unfortunately, the
duration of estrus is extremely variable and can
last anywhere from two or three days to two or three
weeks. Diestrus, the period between two successive
estrus periods, is more consistent in length and
lasts about 14 to 16 days.
