Mare reproductive loss syndrome (MRLS) is a syndrome consisting of equine abortions and three related nonreproductive syndromes which occur in horses of all breeds, sexes, and ages. MRLS was first observed in the U.S. state of Kentucky in a three-week period around May 5, 2001, when about 20–30% of Kentucky's pregnant mares suffered abortions.
Horse breeding is reproduction in horses, and particularly the human-directed process of selective breeding of animals, particularly purebred horses of a given breed.

Such tests include crossmatching the mare's serum to washed red blood cells of the foal, which is added to exogenous complement, and is positive if hemolysis occurs. A direct Coombs test may also be used, but does have a high rate of false negatives. Crossmatching using saline agglutination does run the risk of false negatives, since some ...
Inbreeding depression is the reduced biological fitness that has the potential to result from inbreeding (the breeding of related individuals). The loss of genetic diversity that is seen due to inbreeding, results from small population size. [2] Biological fitness refers to an organism's ability to survive and perpetuate its genetic material.
In clinical practice, post-test probabilities are often just estimated or even guessed. This is usually acceptable in the finding of a pathognomonic sign or symptom, in which case it is almost certain that the target condition is present; or in the absence of finding a sine qua non sign or symptom, in which case it is almost certain that the target condition is absent.
