“Reports in scientific literature indicate that cattle with this extremely short, slick-hair coat are potentially able to better withstand hot weather.”

Many producers in warmer climates utilize Bos indicus-influenced cattle, but several African-sourced breeds also exist that offer the heat and pest tolerance sought by Southern producers.

Adding genetics to traditional American breeds is working. Cattlemen in the southern U.S. tried to resolve this problem by introducing Brahman genetics—beginning in the 1880s.

“Reports in scientific literature indicate that cattle with this extremely short, slick-hair coat are potentially able to better withstand hot weather.”

Pinpointing the chromosomal location of the “slick” gene identified by Agricultural Research Service (ARS) scientists could help breeders develop cattle with shorter, slick hair that helps keep them cool in the subtropics.

Beef production needs to increase from 60 million to 130 million tons by 2050 to feed a growing world population, and 70% of this production increase is expected from beef industries located in subtropical and tropical regions of the world.

The intentional genomic alteration (IGA) in the prolactin receptor gene (called the PRLR gene) truncates (or shortens) the prolactin receptor protein (called the PRLR protein) in Bos taurus cattle and results in a short, slick haircoat.

The Romosinuano cattle breed is one of the most important Creole genetic resources in Colombia, and interesting traits like adaptation or reproductive efficiency have promoted its use in different countries in America.

Breed differences in milk production and milk quality are related to differences in calf preweaning growth, differences in cow maintenance requirements, and differences in efficiency of production.
