Abstract

Now that antibiotic rotation has become a popular way for hog producers to cut drug costs in half without compromising on herd health or efficiency, a few noted swine specialists are challenging their producers to take this program one step further. Instead of feeding grower-finishers a low-cost production antibiotic for three-weeks and a therapeutic additive for one week, they suggest keeping the production antibiotic in the feed from 50 pounds to market weight and rotating to therapeutic additives only as needed.
