UF Buck Test & Sale

We are very excited to be offering the first University of Florida Buck Test and Sale.  We invite you to participate in this unique program beginning in June 2024. The buck test will be conducted from June to September, with the buck test sale following the end of the test. This program will run alongside the UF Ram Test and Sale.


This Buck Test program is designed to standardize environmental conditions to evaluate and quantify individual buck performance in the harsh southeastern US, with a primary emphasis on natural parasite resistance and growth.

Registered and commercial bucks are eligible for the test. Bucks must be born between 12/15/23 and 3/1/24 and weaned by 5/1/24 to participate.

We encourage you to consider consigning your bucks to the UF Buck Test and Sale. Please contact us for further information or to consign animals to this program. Bucks must be pre-registered by May 6, 2024, to enroll in the program.
