Pasture management as a
parasite control strategy
E ective pasture management requires
planning your parasite control strategy
here, the team at Boehringer Ingelheim
o er some advice on this topic.
Planning an e ective parasite control strategy relies upon
establishing specific management systems for individual
farms and pastures. The type of parasite and the level of
challenge will vary from location-to-location and animal-
to-animal. The most common parasites in cattle are
Ostertagia ostertagi, Cooperia oncophora, Haemonchus
contortus, and Dictyocaulus viviparus, which can inhibit
an animal's growth and reduce productivity, in addition to
producing clinical disease. Thus identifying, monitoring and
managing for the exact challenges of your individual farm
is vital. As the conditions on individual farms are highly
variable, a general `one size fits all' blueprint will not be
e ective. Planning an integrated approach that identifies
the risks and utilises both anthelmintic treatments and
pasture management to control a specific parasite threat
will reduce the risk of outbreaks of clinical disease and
loss of productivity. Reducing reliance on anthelmintic
treatments alone also reduces selection for resistant
parasites. The guidelines below outline key areas for
consideration, however your local veterinarian or animal
health advisor can support you to understand and plan a
parasite management strategy that is right for your farm.
Understanding the conditions
To plan e ective pasture management it's important to
know which parasites are on the farm and when and
how they will impact the cattle. Dedicate some time at
housing, at turnout and in mid-summer to reflect on the
e ectiveness of parasite control over the previous months
and plan for the next six months.
