The Rio Grande Valley Beef Improvement Association was created in 1998 to assist cattlemen in the Rio Grande Valley in improving the quality of their livestock.

The initial project undertaken by the Association was to conduct a Bull Gain Test and Heifer Development Program. This is an official gain test conducted by  Texas A&M AgriLife Extension Service under the direction of Dr. Joe Paschal, Extension Livestock Specialist and County Extension Agents in Cameron, Hidalgo, Willacy and Starr Counties.

Successful bull gain tests and heifer development programs have been conducted since 1998. 

The Simbrah, Santa Gertrudis and Beefmaster breeds have been represented in the largest numbers.

Other breeds have included: Simmental, Brahman, Braunvieh, Red Brangus, Charolais, Limousin, Hereford, Angus, Red Angus, Maine Anjou and others.

The Rio Grande Valley Beef Improvement Association is affiliated with Texas A&M AgriLife Extension Service.  Any of the following County Extension Agents will be glad to provide additional information.
