Hygromycin is a '''relatively new" antibiotic that is recommended for its ability to control certain internal parasites in swine. Previous work has shown that it is very effective against roundworms, nodular worms and whip worms. In some of these trials hygromycin has increased gains comparable to other antibiotics. However, these studies did not show whether the increased gains from feeding hygromycin were due to the control of roundworms or due to a growth stimulating effects similar to that exhibited by other antibiotics. In order to obtain more information on the role 6f hygromycin swine feeding this experiment was conducted in which hygromycin was fed alone and in combination with chlortetracycline (aureomycin) to wormed and unwormed pigs.
