Horse Breeding Methods: Live Cover and Artificial Insemination
From 1991 through 1994 or 1995, the breeding method used by
Mr. Rinehart was “teasing” the mares (to determine which mares
were in heat) and doing “live cover” (where the stallion and mare
have intercourse). Mr. Rinehart had a special facility on the
Campbell ranch for teasing the mares.
Around 1994, Mr. Rinehart started using artificial
insemination breeding. Mr. Rinehart gained knowledge of equine
artificial insemination techniques through studying, reading
books, and working with veterinarians while they performed
artificial insemination.
After learning about equine artificial insemination, Mr.
Rinehart purchased artificial insemination equipment. Mr.
Rinehart had the following equipment on the Campbell ranch for
use in his artificial insemination breeding program: (1) Horse
stocks that could be used to palpitate several mares at a time,
(2) a phantom mare (also known as a dummy mare) with an
artificial vagina that was used to collect the stallions’ semen,
(3) a laboratory, (4) incubators, (5) a microscope, (6) a
refrigerator, and (7) cryogenic equipment.
Artificial insemination made it possible for his stallions
to breed with more mares than when Mr. Rinehart used live cover.
As part of his artificial insemination program, Mr. Rinehart set
up a detailed schedule for use during breeding season showing
