Can a Heat-tolerant Cow Breed Be Evolved?

Can a Heat-tolerant Cow Breed Be Evolved?

With global warming becoming a reality, and many countries recording soaring ambient temperature, there has been clamour to evolve heat tolerant breeds. Excessive heat and humidity affects dry-matter intake and energy loss, resulting in losses in milk production and reproduction.

Gir cattle of the Zebu class have become popular worldwide for being hardy, resistant to infectious and parasitic diseases (external as well as internal). With overt changes in climate and wide-spread global warming animal scientists are concerned that milk production may fall drastically as European and American breeds are not tolerant to warm and humid climates.
