How to Prepare Your Older Mare - Mare and Foal Older mares have a knack for being the sweetest and gentlest mares on the farm. We see them year after year, either carrying their own foals or returning to donate embryos if their reproductive status requires. Oftentimes, these mares are considered “special” patients, requiring a unique combination of diet, exercise, and metabolic support to maintain their physical and reproductive health. We often see older performance mares that are being bred for the first time following a long and successful show career. Reproductive problems such as cervical adhesions and uterine infection can be common in older mares which affect their ability to carry a foal or donate an embryo.

The Test Freeze - The First Freeze Performed on a Stallion's Semen

August 28, 2015

Posted by SBS in Frozen Semen

The Test Freeze - Straws on Rack The test freeze is the first freeze performed on a stallion when he comes to a Select Breeders Services (SBS) Affiliate Lab to have semen frozen. We primarily have four different semen freezing protocols that we test on each stallion. The differences between each protocol being in either the extender formulation or the rate of cooling. For subsequent freezes we choose the protocol which gives the best results as determined by post-thaw motility. Regardless of the protocol, once the straws of semen reach -120 degrees Celsius in the programmable cell freezer they are then plunged into a bath of liquid nitrogen at -196 degrees Celsius.

A Stallion Breeding Soundness Exam

July 30, 2015

Posted by Dr. Ed Squires in Stallion Management

CASA In our previous article, My Stallion is Not Settling His Mares…What Do I Do?, we discussed possible causes for the decline in a stallion’s fertility and areas of reproductive management one can investigate further to determine if the infertility can be suitably managed or resolved. One tool a stallion owner/manager can use to better understand the reproductive status of their stallion is to have a breeding soundness exam (BSE) performed. In this article, Dr. Ed Squires outlines the components of a routine BSE which include: physical exam, reproductive history, testes palpation and/or ultrasound, semen evaluation, cultures and an assessment of his sexual behavior. Whether the stallion passes or fails, a BSE provides valuable information on how to  manage the stud and gives an indication of the number of mares he could breed.
