Spring Time Implant Usage By Tammy Winger DVM Many producers are concerned this year with strategies to “cheapen-up” their animal health programs. My thoughts are also on adding value by increasing calf performance with branding implants. Many studies have been completed over the last 20 years that prove implants improve feed efficiency, rate of gain and therefore pounds of calf. Calves can benefit from implanting at any time in their life, but the greatest advantage is at 1.5 to 2 months of age. It has been proven by different companies, universities and private trials that these calves have increased weaning weights of 18-32 lbs. Often ranchers don’t want to implant because they believe that their calves won’t sell as well. That may be true for certain “natural markets” where there is a significant premium actually received. What is the premium needed in a regular market for non-implanted calves to be more profitable? Analysis of market data reveals that a 500lb average weight nonimplanted calf would need a $5.75/cwt premium to make up for a 23lb weight advantage of an implanted calf. What about meat safety? Estrogen level in 1 pound of meat from an implanted steer is 54 nanograms less than natural milk and 1,989 nanograms less than peas. Just to keep it in perspective, an adult man produces 100,000 ng of estradiol per day and one birth control pill has the same amount of estrogen as 125,000 lbs of implanted steer meat. The studies performed on taste, tenderness and palatability differences are also negligible. In a few of the studies, the participants rated the flavor of the implanted meat higher. In conclusion: Implants at branding increase weaning weights and pounds of beef marketed. Meat from implanted animals is very safe to eat and tastes the same as or even better than non-implanted meat.
