Outbreeding– The process of continuously mating females of the herd to unrelated males of the same breed.

Forms of Outbreeding:

  • Outcrossing- the mating of unrelated animals
  • Grading up- the mating of purebred sires to nondescript or grade females and their female offspring generation after generation
  • Linecrossing- the crossing of rather distinct lines (that may or may not be inbred) of the same breed
  • Crossbreeding- the mating of animals of different established breeds
  • Species cross- the crossing of animals of different species
