Outbreeding

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
