On behalf of our consignors, our committee and myself, I would like to welcome you to our third online bull sale.  We are excited to offer you 22 bulls of 6 different breeds,  Angus, Brahman, Braunvieh, Santa Gertrudis, Simbrah and Simmental,  who have an overall test ratio of 100 or better and have passed a fertility test and are negative for trich.  These bulls are put on 110 day gain test and are measured for Average Daily Gain (30%), Rib-eye Area/cwt (20%), Weight per day of Age (20%), Percent IMF “Marbling”(20%) and Scrotal Circumference(10%).  Bulls are ranked by breed and by age.  This year we had four age groups, Senior Bulls – Spring 2018, Intermediate Bulls – Summer 2018, Junior Bulls – Fall 2018 and Calf Bulls – Spring 2019. 

The Rio Grande Valley Beef Improvement Association was created in 1998 to assist cattlemen in improving the quality of their livestock.  The bull gain test is an official gain test conducted by Texas A&M AgriLife Extension Service, under the direction of Dr. Joe Paschal, Extension Beef Specialist and Count Agents in Cameron, Hidalgo, Willacy and Starr Counties.  Successful bull gain tests and heifer development programs have been held every year since 1998.  A total of 1420 bulls and 1050 heifers have gone thru this program. 

I would like to thank Mike Risica, Rio Beef Feedyard, and his staff for being so accommodating to this program and helping care for our bulls and heifers.  Bulls are available for viewing at Rio Beef Feedyard, Linn, TX.  If you have any questions please do not hesitate to contact me, Carlos X.
