Why do farmers practice cross breeding?

Cross breeding allows the improvement of standard production traits such as milk production, growth rate and production of total animal protein. Improved variety of cattle and other livestock can increase production efficiency and can reduce the amount of resources and inputs farmers require for livestock production.
