The Florida Bull Test is underway with 45 bulls on feed at the University of Florida's North Florida Research and Education Center near Marianna, Florida. Fourteen consignors from Florida, Alabama, Georgia, and North Carolina brought their best bulls to have their performance measured on an equal playing field. There are 26 Angus bulls, 6 Simmental, 4 Hereford, 3 Limousin, 2 Santa Gertrudis, 2 Red Angus and 2 Parthenais currently on test. These bulls were all born between August and December of 2006.

The bulls were delivered in September and have been on full feed for comparison since September 25. The bulls will be fed and measured for 84 days, and the test will be complete on December 20. In previous years, the Florida Bull Test had been 112 days on full feed, but due to rising feed prices the test was shortened to keep consignment costs from rising. Through the first 56 days of the test, the entire group of bulls averaged 4.14 pounds of gain-per-day with an average weight-per-day-of-age of 3.25. Twelve bulls, however, are gaining over 5 pounds per day and are currently leading the test. The average is subject to change over the final 28 days of the test, but this is a good indicator of the quality of the bulls on test this year.

Activities with the Bull Test will conclude with the annual sale to be held on Saturday, January 19, 2008. Not every bull in the test will be auctioned. Some consignors will keep their best bulls and the lower performing bulls will be excluded from the sale, so there should be around 30 bulls offered at auction. As in previous years, bulls have been measured not only for gain on feed, but also for carcass traits using ultrasound technology. Producers will have EPD's, actual performance and ultrasound data, as well as pedigree information to aid in the selection of excellent quality bulls to purchase. For more information on the Florida Bull Test, visit the web page at, or telephone 850-482-9904. Catalogs will be available by request and will be printed and sent out to those who request them after the first of the year. Note: the Research Station office will be closed from December 24-January 1.
