commercial corner post GW provide would make one think nearly every steer turned out should have one in its ear. However, according to the 2008 National Animal Health Monitoring System (NAHMS) survey, the use of implant technology in suckling calves has actually declined from 14 percent to 9.8 percent over a tenyear period. The reasons for this decline are not fully known or understood. Some of these non-implanted calves are likely being sold into specialty or branded programs that prohibit anabolic implant use. However, another reason cattle managers leave suckling implants out of their tool box is the â€œstigmaâ€? that calves implanted in the suckling phase are discounted at the sale barn. In 2015 Rogers and colleagues published results from studying the effects of growth-promoting implant status on sale price of beef calves sold through livestock video auction services from 2010 to 2013. Over the three years they noted about 28% of the weaned steers marketed had received an implant prior to weaning. They found that implant status of calves
had no effect on the sale price of beef calves. In other words there were no discounts as a result of using implant technology or more over no cattle received premiums for their non-implant status. Another reason suckling calf implant use may have declined is the thought that previously implanted calves do not respond as well to subsequent implants in the growing and finishing phase. Two SDSU studies, one by Pritchard and colleagues (2015) and one by Web and colleagues (2017) further studied the impact of suckling calf implants on post-weaning live animal and carcass performance. Both studies found there were no effects on average daily gain, or feed efficiency in the receiving, backgrounding or finishing phase if a calf was previously implanted during the suckling phase of life. Both studies found there were no negative impacts from suckling implants on subsequent carcass characteristics. So after ruminating on all thatâ€”who will take the deal proposed in the first paragraph? D Courtesy of igrow.org
