Foaling season is officially upon us and right about now equine veterinarians have little else on the brain but colostrum. That’s how important colostrum is to a newborn foal; it can literally mean the difference between life and death.  In this article the members of FullBucket, a company providing veterinary strength supplements for horses and dogs, discuss the foal's immune system, why colostrum is such an important factor in the their first hours of life, and what you can do to ensure their life starts right.

Biofilms in Mare Reproduction

February 27, 2015

Posted by Dr. Ryan Ferris in Mare Management

A biofilm has been proposed to have a significant role in chronic infections in the horse. It has been suggested for over a decade that chronic uterine infections resistant to antimicrobials may be due to biofilm production. The involvement of a biofilm in cases of bacterial endometritis has not been clearly elucidated, but many reproductive specialists suspect a biofilm plays a significant role in infectious endometritis. In this article Dr. Ryan Ferris, a board certified theriogenologist from Colorado State University, explains the lifestyles of bacteria, how a biofilm is formed, how they protect bacteria and their implications on equine reproduction.

Cryopreservation of Equine Embryos

January 30, 2015

Posted by Dr. Dave Scofield in Mare Management

Embryo vitrification doesn't sound much like "freezing embryos,” but the end product certainly is a cryopreserved equine embryo, frozen in liquid nitrogen for the preservation of genetics and transfer into a recipient mare at a later time. For the sake of some readers of this blog, an embryo is the result of fertilizing an oocyte (egg) with sperm and allowing the initial stages of development to occur. Embryo vitrification is the process whereby we freeze equine embryos for storage for indefinite periods of time prior to transfer into a recipient mare. We have the technology to cryopreserve equine sperm and equine embryos, but not equine oocytes. Herein lays the answer to the most common question that comes up in conversation regarding this blog topic. Some readers assume that since we can freeze the male generated sperm, we can likewise freeze the female generated oocyte. Unfortunately, due to some very sensitive cytoskeletal components in the oocyte, the technology does not exist to freeze equine oocytes. As we proceed, you will understand the process of embryo vitrification and we will delve into areas of research that are improving the success rates of vitrified embryos in generating live foals.

Ovum Pickup in the Mare

January 03, 2015

Posted by Dr. Gabe Young in Mare Management

Breeding horses has come a long ways in the last 50 years. Veterinarians have been able to overcome many of the obstacles presented when breeding horses with advancements in artificial insemination and embryo transfer. However, there are still times when infertility of either the mare, stallion or both prevent getting foals on the ground. The most recent advances in assisted reproductive technologies, Ovum Pickup and Intra-Cytoplasmic Sperm Injection (ICSI), have allowed us at Weatherford Equine Breeding Center (WEBC) to take the next step in overcoming these obstacles with some promising results.
