Maxine Lyndall-Murphy, WormBuster Lab, Brisbane, (Maxine.Lyndal-Murphy@deedi.qld.gov.au):
It is concerning that the increase in rainfall this year is being followed by very high worm egg counts on properties across southern Queensland. Despite this, many producers in the more extensive regions are commenting how well their sheep are looking not suspecting that they might be harbouring a stomach full of Barber’s Pole worms waiting to cause havoc. Worms compete for host's nutrition and if left unchecked they can manifest initially as a nutritional problem.
If worms are not treated and sheep are joined without reaching their target live weights, poor nutrition through winter will result in poor lambing percentages.
Test for worms using the WormTest kits available from the laboratory 3255 4251 or your reseller or use the on-farm dipstick test.
