Abstract

The results are presented of a long-term study in Queensland in 1965-75 on the effectiveness and economic advantages of 2 methods of controlling ticks [Boophilus microplus (Can.)] and the pathogens they transmit (Babesia bovis and Anaplasma marginale) in Droughtmaster, a relatively tick-resistant...

Abstract

Strategic dipping and pasture spelling plus dipping were compared in Queensland with no treatment on Droughtmaster cows and their progeny over 5 years. Average monthly counts of Boophilus microplus (Can.) on the young cattle and their dams were 10 and 18, <1 and 2, and 56 and 112, for the 3 treatments, respectively. There was stable transmission of Babesia bovis, B. bigemina and Anaplasma marginale to the progeny from the untreated cows. Strategic dipping, and pasture spelling plus dipping, seriously disrupted the transmission of B. bovis, and vaccination against this parasite is recommended. Pasture spelling plus dipping also interfered with the transmission of A. marginale and B. bigemina, but vaccination against A. marginale only is warranted. At 27-29 months of age, the young cattle in the strategic dipping group had...
