Two germicides, one containing 0.5% @entity1216 and one containing 1% @entity1496 , were tested for efficacy against new intramammary infections (IMI) caused by @entity794 and @entity5967 . The model for the experimental challenge in the trials that were designed to test the efficacy of the two postmilking teat dips was recommended by the National @entity1271 Council. The 0.5% @entity1216 product reduced the number of new IMI caused by Staph. aureus by 73.2% and reduced the number of new IMI caused by Strep. agalactiae by 53.9%. The 1% @entity1496 product reduced the number of new IMI caused by Staph. aureus by 75.6% and reduced the number of new IMI caused by Strep. agalactiae by 53.5%. In both trials, the incidence of clinical @entity1271 was also reduced in dipped quarters compared with control quarters. Use of the two teat dips over the trial periods had no effect on the condition of teat skin or teat ends.
