What is a remote drug delivery system (RDDs)?
By this point, chances are you’ve seen, utilized or are at least somewhat familiar with remote drug delivery systems (RDDS) in cattle. The concept of using darts to give a full therapeutic dosage of antibiotics at long range has taken life in the cow-calf segment.
Is remote drug delivery of Tulathromycin in cattle unsuccessful?
Research conducted at Iowa State University found in four of 15 calves, remote drug delivery of tulathromycin was unsuccessful. This study also found using 1.9-centimeter, 14-gauge needles to deliver the same dosage caused increased acute stress and muscle damage when delivery was done with RDD technologies compared to handheld.
Which RDDs is the most BQA-compliant?
Of the different RDDS on the market, Griffin believes Pneu-Dart is by far the most BQA-compliant. “Pneu-Dart has two darts (one-half-inch and three-fourths-inch tri-port) that fit BQA needs,” he says.
