Breeding farms are hotspots for contagious equine metritis (CEM) and equine viral arteritis (EVA). MBS maintains a strict "Closed Barn" policy. All visiting mares must quarantine for 72 hours. MBS stallions are vaccinated for EVA annually, and swabs are taken from the urethra and penis before every breeding season.
MBS maintains a separate herd of 150+ recipient mares. These are healthy, robust mares with impeccable maternal instincts, used for embryo transfer programs. This allows the premium MBS Series stallions to sire up to 3x more foals per season without physical strain. mbs series stallion breeding farm
