Featured News: Why SBS Requests Disease Testing of Stallions

Feature RSS Feed

August 07, 2016

Select Breeders Services (SBS) and its affiliate labs require current negative test results for specific diseases for stallions presented to our facilities for freezing which can include Contagious Equine Metritis (CEM), Equine Viral Arteritis (EVA) and Vesicular Stomatitis (VS) as well as a negative Coggins. Depending on the facility, the tests may be required prior to the stallion’s arrival or performed at the time of collection. What does all that mean and why are these negative tests necessary? In this article we will discuss the way these diseases are transmitted, how they can be prevented, why we require they be performed and provide examples of what can happen if an outbreak of these diseases occur.

Featured Blog: Ground Collection of the Stallion

Blog RSS Feed

August 06, 2016

For most facilities, using a phantom is the preferred method of collecting semen from a stallion, as it is an efficient, organized and generally a safe process that mimics the natural position during live breeding. Ground semen collection (see video below) is an alternative option to the typical collection of a stallion on a phantom or mount mare. This article describes ground semen collection, primarily summarizing previously published clinical and research reports of Sue McDonnell and colleagues at the University of Pennsylvania and Jim Crump of Roanoke AI.

Featured Question

How old does my stallion have to be for semen collection?

We suggest a stallion be at least 3 years of age before starting semen collection. At this age most stallions have matured both mentally and physically and are able to handle the additional stress of becoming an active breeding stallion. Typically, by the age of three their testicles have matured and have begun producing sufficient semen which is suitable for cooling or freezing. It is possible to collect younger stallions and we have successfully collected and frozen semen from 2yr olds. However, we always caution stallion owners to be aware that at this age semen quality may not be acceptable for processing. Even if it is, total sperm production is often less than would be expected at maturity and therefore it may not be financially viable to proceed with a comprehensive semen freezing program at that time.
