Selecting and Breeding the Unique Brahman
ثبت نشده
چکیده
The American Brahman, unique in many ways, differs from cattle of European origin in form, physiology and genetic make-up. The Brahman is generally utilized to complement rather than compete with others breeds. Even though the same basic genetic principles operate for Brahmans as for any other breed, goals are different and the gene pool and distribution of the Brahman population is different. It follows, then, that breeding and selection programs for the Brahman should be designed especially for this breed.
