Outcrossing and cross breeding are 2 breeding practices in animal husbandry. How are the two practices different from each other and what advantages are they do the breeders?

Out-crossing − It is the mating between animals of same breed, but not having common ancestors for 4 − 5 generations.

Advantage:
It is usually used for animals, which have below average productivity and growth rate.

Cross-breeding − It is the mating between a superior male of one breed with a superior female of another breed.
Advantage:
Superior qualities of both the breeds combine and this is known as hybrid vigor. The progeny so formed is called a hybrid. A hybrid may be used directly for commercial purposes.
