Trichomonas foetus infection in a beef herd.

Abstract Sir,—Trichomoniasis has for many years been recognised as a bovine venereal disease. The last New Zealand case reported was in 1972(2). A recent investigation of a low reproductive performance problem in a beef herd in the Tokomaru Bay area of the East Coast has again confirmed the disease's continued presence. This brief report is to remind veterinarians of the current existence of New Zealand bovine trichomoniasis and to describe methods of attempted control.
