The Florida Bull Test 2008–20091

G. Cliff Lamb2

Test Procedures

The 2008-2009 Florida Bull Test consisted of an 84-day performance test and a breeding soundness evaluation of each bull that qualified for the auction. Upon arrival, bulls were sorted into contemporary groups, and moved into 3.25 acre pens where bulls received free choice access to a corn-based concentrate supplement, grass hay, and water with a target weight for the bulls to gain of 3.0 lbs/day. The concentrate supplement consisted of 65% corn and 35% Accuration (a supplement formulated by Purina® to limit grain intake and provide all required minerals for growing bulls). After a two-week adaptation period, bulls were walked from their home pen and weighed on two consecutive days to obtain an objective average starting weight; this weight became the on-test starting weight. Bulls were inspected daily for any health problems that may have arisen. Intermediate un-shrunk weights were obtained every 28 days during the test. At the conclusion of the 84-day feeding period, bulls were again walked from their home pens to the main facility and weighed on two consecutive days to determine final test weight. Animal performance, specifically average daily gain (ADG), was calculated using only the official starting and finishing test weights. Throughout the test, bulls were observed and screened for structural soundness and disposition. Bulls deemed to be structurally unsound or those having poor disposition did not qualify for the sale.

Test Rules and Regulations

General Policies and Procedures

  1. Bulls must be born between September 1 and December 31 of the preceding year.

  2. All consignors' herds must be enrolled in their respective breed association performance program. State beef cattle improvement association programs are acceptable for herds whose breed association does not have a performance records program.

  3. Calves must have completed the weaning phase of the performance record program with their contemporary group and this information must be presented at delivery. If data has not been returned from the association, a copy of the weight data with the number of contemporaries must be provided.

  4. All calves must be purebred or full blood and registered with their breed association. Composite bulls must have both sire and dam registered in an acknowledged beef breed association. A registration certificate and pedigree must accompany each bull at delivery to the test station to participate.

  5. A bull should weigh 2.5 pounds per day of age when delivered to the test station. A transit shrink of 1% per hour of transit time will be allowed.

  6. Bulls must be weaned a minimum of 3 weeks prior to delivery.

  7. Bulls must be structurally sound and show evidence of good growth potential.

  8. Bulls below frame score 4 will not be accepted (BIF frame score chart).

  9. Bulls actual birth weight is required.

  10. Consignments over 10 head will be accepted on a space available basis.

  11. Priority for space will be given to Florida residents. Bulls from other states will be accepted on a space available basis.

  12. Sire-group testing of bulls is more desirable than individual testing because it provides more information to both breeders and prospective buyers; therefore, they will receive preference if space becomes limiting.

  13. Breeders/consignors must be members of the Florida Cattlemen's Association.

  14. Embryo transfer bulls must be designated as such, and the breed of the recipient cow designated.

  15. Bulls must have legible permanent identification (tattoo or brand) corresponding to registration paper at delivery.

  16. Horned bulls will be grouped separately. It is recommended that they be dehorned and healed at delivery.

Health Requirements

  1. All bulls must be in good health and accompanied by a health certificate showing they are from a Brucellosis-free accredited or certified free herd with the herd number on the health certificate or have a negative test for Brucellosis not more than 30 days before delivery. Bulls originating from a state that is not T.B. free must also be accompanied by a health certificate showing they are a certified T.B. free herd or have a negative test for T.B. not more than 30 days before delivery. All bulls will be tested for T.B. upon arrival.

  2. Bulls must have been vaccinated twice (minimum 21 days between vaccinations) for 5-way leptospirosis, 7- or 8-way clostridium with haemophilius somnus, IBR/PI3/BVD/BRSV and with the last vaccination at least three weeks or more prior to delivery. Pasteurella, is optional. Inter nasal IBR/PI3 is recommended.

  3. Consignors are responsible for the cost of treatment if their bull requires examination by a veterinarian.

  4. Consignors should contact their local or state veterinarian for interstate permit and health requirements. An official certificate of veterinary inspection (health paper) is required for each bull.

Test Results

Overall ranking for the test was determined using an index ratio calculated from ADG and the weight per day of age (WDA). All results are represented in Table 1. The top performing bull and top performing Angus bull in the test was CWL Yield Grade 7172, owned by Lawler Farms of Opelika, AL. This bull indexed 128 with an ADG of 4.87 and WDA of 3.29. The top Limflex bull, SAYF Hunt 56T owned by Sayer and Sons Farm from Ambrose, GA, was ranked third overall and indexed 121 with an ADG of 4.55 and WDA of 3.14. The top Charolais bull, GDM Mr Will 7153 owned by Meadows Creek Farm from Columbia, AL, was ranked 12th overall and indexed 113 with an ADG of 4.06 and WDA of 3.11. The top SimAngus bull, CLS T157 owned by C & L Farm from Valdosta, GA, was ranked 18th overall and indexed 109 with an ADG of 3.67 and WDA of 3.26. The top Simmental bull, KSI Real Deal 85T owned by Keller's Simmental from Alma, GA, was ranked 23rd overall and indexed 105 with an ADG of 3.60 and WDA of 3.09.
