Carcass Challenge Guidelines & Requirements

General Guidelines

Producer Requirements:
• Must be a 2016 member of ICA.
• Reserve pen space on a commitment form by Oct. 1, 2015. If we do not have a minimum level of commitments, the contest may be cancelled and all donors will be notified.
• Deliver steers on Tuesday, Nov. 10 to designated Feedyard or to a designated pick-up location and assign ownership of the steer(s) to ICA.

Steer requirements:
• Steers must be 2015 spring born calves that weigh between 650 pounds and 750 pounds. No dairy type cattle.
• Receive all mandatory vaccinations, preferably with a modified live vaccine, prior to or during the suggested vaccination dates of Sept. 11, 2015 to Oct. 20, 2015 and be weaned at least 21 days.
• Steers that are unable to adapt to feedlot conditions at any point in time, or that encounter challenges while on-feed may be sent to market prior to the group marketing. The donor will be informed of the animal being marketed.

Health and Vaccination Requirements:
• Steers will be allowed to enter a test only upon meeting the following requirements and being so certified by a veterinarian on a health form to be provided.
• Weaned at least 21 days before delivery.
• Vaccinated for the following at least 21 days but no more than 60 days before delivery (preferably a month before delivery): BVD (Bovine Virus Diarrhea); IBR (Infectious Bovine Rhinotracheitis); PI3 (Para-Influenza 3); Pasteurella - New Generation Vaccine; Clostridium Chauvoeri, Septicum (Blackleg and Malignant Edema); Haemophilus Somnus (Shipping Fever) - Somnugen; & BRSV (Bovine Respiratory Syncytial Virus).
• Steers originating outside Iowa must conform to official interstate health regulations. All steers must have state health certificates at delivery.
• Treated for worms and grubs prior to delivery.
• Free from evidence of warts, ringworm or mange.
• All calves must be dehorned and healed prior to delivery.
• Steers will be implanted upon arrival at the feedyard. Depending on weaning date (days prior to delivery), the weaning implant may be skipped.
• Steers will receive the following booster shots at delivery to the test station: Killed BVD, Nasal IBR, Haemophilus Somnus, BRSV, Pasteurella, Micotil, and Dewormer.

Performance Guidelines
• The feedlot will implant the cattle at arrival and again at approximately 80 days prior to harvest with Elanco’s portfolio of implants. Steers will be fed Optaflexx during the final stage of feedlot phase.
• Steers may also be DNA-tested for carcass traits, tested for persistently infected BVD and ultrasounded for carcass traits while on feed. Donors will receive all information collected.

• Top five Retail Value per Days on Feed (RVDoF) will receive cash prises of 1st - $750, 2nd - $500 and 3rd-5th - $250 and a jacket noting their placing.
• The Retail Value Per Day On Feed (RVDoF) formula shown below* is a popular method used by similar carcass contests, and is highly representative of the profitability of a carcass. The formula calculates the carcass value gained during the feeding period. This is done by calculating red meat yield gain, then taking that times a carcass price which reflects differences and quality grade, then dividing it by the days on feed.
*RVDoF = {[HCW - (0.55 x Start Wt) x (%RP) X (carcass price/0.64)}/0.64/days on feed
   *where Retail Product (RP) = [65.69-(9.931 x back fat) + (1.2259 x ribeye area) – (0.013166 x carcass wt) - (1.29 x % KPH)]
   *where carcass price per pound is determined by the appropriate grid
   *where %KPH is the percentage of total fat found in the body cavity of a carcass specifically in the regions of the kidneys, pelvis and heart.

• Top five Carcass Merit - Carcasses will be ranked on a grid price per pound. Carcasses will then be adjusted in placings for the following: 1) Any carcass with a REA less than 1.5 sq. inches per 100 pounds of hot carcass weight will be lowered three ranks; 2) Any steer with less than a 2.5 ADG will be lowered five ranks; and 3) Carcasses with excessive trimming will be lowered two ranks. Tie breakers will be as follows: 1) Marbling score; 2) Calculated yield grade score; and 3) Retail value rank. The top five entries receive cash prizes of 1st- $750, 2nd - $500 and 3rd-5th - $250 and a jacket noting their placing.
• Each of the following categories will receive a cash prize of $250 and a jacket noting the award: largest ribeye area (REA), top marbling score and the chef award (12” to 14” ribeye with the highest marbling score).
• Two ICA Carcass Challenge caps will be given for each donated steer.

Iowa Cattlemen’s Association will:
• Help the ICA Young Leadership class solicit steers for test and assist in planning and developing an educational feedyard event in the spring of 2016 while the steers are on-feed.
• Send update reports to donors and interested parties following processing weights at delivery and implant time, as well as the final report following harvest.

General Considerations:
• Calves should be accustomed to consuming a grain ration, i.e.: 5-6 pounds of grain with forage.
• Feedyard is a state-of-the-art yard with a step-up feeding program and end point targeted feeding. They utilize new technologies, including Elanco’s Optaflexx, and a complete implant program.
• Neither feeder nor ICA may be held liable for sickness or death loss of any steer.
• Steers will have fat thickness, loin eye area and percent fat in ribeye measurements taken at harvest. This information will be used in calculating the percent retail product and retail product per day on feed formulas.
