The implant on the left was administered with a dirty needle into
a dirty ear while the one on the right was given with a clean needle
and ear. Notice the evidence of swelling and infection of the site
fourteen days after the implant. While the ear is not an important
retail product in the beef industry, the lack of attention to cleanliness
still represents lost money. The infection in this site will prevent
the absorption of the product and hence, the desired response to
the implant. The producer loses the cost of the implant and the
labor required for administration.
Notice the implants in the ear on the right are in a nice row under
the skin above the cartilage. These will be easily absorbed over
the life of the implant, providing the desired animal response.
