Possible lack of efficacy reported by the company Vet. Nine cattle were treated with Boss pour by the producer because of poor physical appearance and for treating ticks. It is reported that three of the nine animals have died. The attending vet did not see the animals. Awaiting more information, case is on going. Update 05 May 2011, a necropsy for the dead animals will not be possible, the producer has already disposed of them. The TS vet has suggested to the attending vet to visit the farm. More information is required on the general situation, management and health of the herd. The attending vet had performed a C section on one of their cows a few weeks ago and the cow was thin.
