(e) Conditions of use. It is used in feed for swine as follows:
(1) Amount per ton. 100 grams tylosin and 100 grams sulfamethazine.
(2) Indications for use--(i) Maintaining weight gains and feed efficiency in the presence of atrophic rhinitis; lowering the incidence and severity of Bordetella bronchiseptica rhinitis; prevention of swine dysentery (vibrionic); control of swine pneumonias caused by bacterial pathogens (Pasteurella multocida and/or Corynebacterium pyogenes); for reducing the incidence of cervical lymphadenitis (jowl abscesses) caused by Group E Streptococci.
