Abstract
Getting cattle to put on a lot of muscle quickly is a crucial part of a beef cattle operation’s profitability. Growth promoting implants are one of the most cost-effective ways of increasing lean tissue in cattle and work by releasing hormones into the cow’s body that encourage muscle growth. This 4-page fact sheet explains implants’ mechanisms of action, how implants are administered and used, and concerns associated with implants.
