University of Florida Ram Test and Sale

By: Dr. Brittany Diehl, DVM, MS

Here in “The Swamp”, we currently have our third annual UF Ram Test ongoing this summer at the University of Florida! This program is designed to standardize environmental conditions to evaluate and quantify individual ram performance in the harsh southeastern US, with a primary emphasis on natural parasite resistance and growth.

This is a forage-based ram performance test where the rams have continuous access to Bahiagrass pastures and are supplemented 2% of their body weight daily with the ‘UF Ram Test’ concentrate ration. Upon entry to the program, all rams receive anthelmintics to ensure the rams entered into the test do not harbor drug-resistant parasites. Those that do not achieve adequate fecal egg count (FEC) reduction are disqualified due to harboring anthelmintic-resistant parasites. After the 12-day acclimation period, the rams begin the 84-day gain test. Throughout the test period, measurements of body weight, body condition score, FAMACHA score, and fecal egg count will be obtained.

New this year, both registered and commercial rams are eligible for the test and sale. Eligible rams must have been born between 12/1/22 – 2/15/23 and weaned by 5/1/23.  Sale eligibility is based on both fecal egg count and growth indices during the test period. The final requirements for sale eligibility include achieving a ‘satisfactory’ breeding soundness evaluation. Sale order priority will be given to rams registered within a recognized breed association, followed by commercial rams.
