Cattle, Atroban Ear Tags for Face Fly and Horn Fly Control, 1982

Abstract

Abstract Five Atroban permethrin ear tag formulations were tested on beef cattle for face fly and horn fly control. These differed as to the DOP plasticizer percentages, permethrin concentration, cis:trans isomer ratio and dyes. They were compared on mixed cow-calf herds ranging in size from 23 to 35 cows. Only the cows were treated with 1 tag per ear. One treatment was applied by stapling ear tag strips containing the commercial Atroban formulation onto the backside of the cattle identification ear tags and allowing the strip to extend 0.5 in below the ID tags. Treatments were applied during the first week in Jul. Each Atroban treatment was tested on 1 herd of cattle. A similar herd of untreated beef cattle within the area was used as the untreated check for evaluating the effectiveness of the tags. Face fly and horn fly counts were made on 10 cows in each treatment before tagging and at regular post-treatment intervals.
