10 FEED•LOT December 2018 of production. In order to determine which implant should be given and when, work backward from the day the cattle should be sent to slaughter or sold. If your implant is going to run out prior to the cattle being sold, consider re-implanting. It is common for cattle to receive 1 to 3 implants in their lifetime. Choosing the correct implant is a step in the right direction; however, the la- beled payout period can be reduced if the implant is not administered appropriately. Implanting procedures are extremely important in order to maintain efficacy of the implant. If implants are placed improperly or become infected, they will not release hormones as they were designed, which can greatly affect the potency. Infected implant sites can cause expelled implants or a quicker than normal payout re- sulting in bullers. Bullers can also be caused by implants that are crushed. To help prevent these issues, implants should be given with the gun designed for that implant, and guns should be kept in good repair with sharp needles. Implants should be placed in a clean, dry ear. If the calf's ear is caked in mud and/or manure, the ear needs be cleaned using a solu- tion of Nolvasan ® water and a scrub Implants are one of the most profit-driving technologies avail- able to cattle producers today. When implemented properly, im- plants contribute as high as a 14:1 return on investment (ROI). Two important things to consider, and review annually, when incorporat- ing an implant protocol into your operation are selecting the correct implant program and using appro- priate implanting techniques. Last month's article provided a chart that outlined implants cur- rently available, as well as sug- gested ways to incorporate them into your operation. There are two primary compounds found in implants; the first are estrogenic compounds that mimic the natu- rally occurring hormone estrogen and the second are androgenic compounds that mimic the natural- ly occurring hormone testosterone. These compounds slowly release hormone into the bloodstream over time. The length of time that an implant releases hormone is known as the payout period. As mentioned in last month's article, different implants are formulated to have different payout periods. In order for an implant to pay for itself and have the greatest ROI, the implant needs to match up with the number of days on feed and stage Getting the Most Out of Your FEEDLOT FOCUS BY -$1$*5$0.2:3+' *5($73/$,16/,9(672&. &2168/7,1*,1&
