INFORMATION ON TRANSPORTED COOLED SEMEN FOR

Evincing

Double L asks that you make sure your mare is ready and healthy.  Please, make sure your mare is not in her transitional heat.  Only 10% of mares in this heat will release their follicle.  Make sure the vet you are using is an equine vet and he or she is knowledgeable about transported, cooled semen. 
 

 Our collection days are Monday, Wednesday and Friday.

February 1 to June 1
 

PREVENT PROBLEMS WITH SHIPMENTS BY FOLLOWING THESE RECOMMENDATIONS:

1.  If your shipment does not arrive, call UPS 1 (800) 742-5877 with your tracking number.

2.  All Semen Orders must be placed by calling (618) 623-9490 by the night before or 10:00 a.m. CST on the day you will be needing semen. 

3.  DO NOT OPEN YOUR SEMEN CONTAINER until your veterinarian is present and ready to inseminate.  Put box in refrigerator if your vet won't be there within the hour.

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 insemination doses 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. Under no circumstances should the semen be used for any other mare, than the mare booked.

6.  Disposable shipping container must be returned to Chris Arentsen Quarter Horses, wrapped the the protective plastic liner enclosed in the box.

7.  Stallion fees and shipping fees are the responsibility of the mare owner and must be paid in full prior to any shipped semen,  unless other arrangements have been made.

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.
 

It 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 three-year-old.
 

If 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:  The 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.

    
POOR MANAGEMENT OF BREEDING IS THE SINGLE MOST IMPORTANT CAUSE OF REPRODUCTIVE INEFFICIENCY IN THE HORSE.
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.

BREEDING ON THE FOAL HEAT.
The foal heat is characterized by normal follicular development and ovulation by Day 20 post-partum
in almost 100% of mares. Most mares return to estrus approximately five to eight days after parturition, with the average interval from birth to first post-partum ovulation being ten days. If your mare is ready to breed in 5 to 7 days, short cycle her, as she is not ready to be bred.
