Cooled Transported Semen Procedures
- Equine pregnancy via shipped semen requires intensive mare management.
Consistent teasing and ultra sounding of mares is necessary to accurately
predict time of ovulation which dictates time of shipped semen request. Your
veterinarian should be familiar with the many aspects of equine reproduction
including ultrasound of mare and motility evaluation of semen.
- Return a signed contract to Bosen Land & Livestock. Include the
appropriate booking fee. This reserves a shipped semen breeding to the
stallion.
- Prior to shipment the mare owner must pay the booking fee and balance of
the stud fee. These fees may be paid by check or VISA or MasterCard.
- Once your veterinarian detects your mares first day of heat contact Bosen
Land & Livestock for a tentative shipment date. Stallions are collected on
Mondays, Wednesdays, and Fridays.
- While in estrus the mare should be examined daily by ultrasound to follow
follicular development HCG (human chorionic gonadotropin) is extremely useful
in a shipped semen program. When the mare has a dominant follicle (35 mm or
larger), estrus folds (as determined by ultrasound), and is in at least her
third day of behavioral heat HCG (3300 IU given IV) can be administered and
will predictably induce ovulation in approximately 36 hours (14-43 hour
range). Ideally, HCG should be given after the veterinarian has ordered semen
and 24 hours prior to expected time of mare insemination. Some veterinarians
may prefer to administer HCG at time of insemination. HCG should not be
utilized more than two or three times per season as mares become less
responsive and there is an increased risk for allergic reaction. Avoid HCG
usage in foal heat mares as decreased pregnancy rates have been noted in such
mares.
- When the mare is ready for the semen shipment contact Bosen Land &
Livestock prior to 9:00 am. of the collection day to make an order.
Orders may be canceled by 9:00 am. collection day with no penalties. For
example, if your mare is to be bred on a Monday or Tuesday you must order
semen prior to 9:00 am. Monday.
- We ship semen via Federal Express Priority Overnight under most
conditions. Some areas of the country do not have Priority Overnight service,
Therefore, the shipment will be standard overnight. Priority arrives by
next day 10:00 am. and Standard arrives by next day 3:00 p.m. Most areas have
Saturday delivery. However, some areas do not. Before requesting a
Saturday shipment make sure Saturday delivery is an option for your area.
Federal Express is not open on Sundays or holidays. Counter to Counter
same day delivery service, via Delta Dash is available to most airports at an
extra cost. Please call for details.
- When you receive the semen shipment, DO NOT OPEN THE Container UNTIL THE VETERINARIAN IS PRESENT AND READY TO INSEMINATE. Use one entire breeding dose
when first received. The dose should be directly inseminated (cold) into the
mare. A 1-2 ml sample should be warmed to 37 degrees C for 1-3 minutes
and evaluated for motility. If a second dose is included, use it within 36
hours of collection (a card is included with the shipment which gives
information such as collection time, breeding dose, etc.). Generally one
breeding dose of semen containing 1 billion motile sperm will be sent per
shipment. If extra semen is available, a second dose will be shipped to
allow for a second insemination or to provide backup. Discard all unused
semen. The blue packages (ballast bags) contained in the Equitainer serve as a
cooling aid. These blue packages should not be opened and should be returned
with the Equitainer the semen is intended for one specific mare and should not
be used to inseminate other mares.
- Return the Equitainer by Federal Express Priority Overnight service.
Penalties of $10/day will be charged Equitainer not returned by the third day
- It is strongly recommended that mares be checked for pregnancy at 14-16
days post ovulation by ultrasound. This will greatly reduce pregnancy losses
from twins. We also encourage the mare be ultra sounded again at 15 days for a
heart beat and to insure development is progressing normally. When the ‘mare
has been checked 15 days in foal, please notify us that your mare is indeed in
foal.
- Please call with questions and/or discussion. With good
communication and an effort to work together we hope to get all your mares
in foal. Our phone number is (208) 852-3130.
