minimising the development of anthelmintic resistance, and optimising the use of the novel anthelmintic monepantel, for the sustainable control of nematode parasites in australian sheep grazing systems.to compare the risk of different treatment scenarios on selecting for anthelmintic resistance on australian sheep farms.201121495986
anthelmintic efficacy of five tropical native australian plants against haemonchus contortus and trichostrongylus colubriformis in experimentally infected goats (capra hircus).the study of the anthelmintic properties of plants rich in plant secondary metabolites can provide ecologically sound methods for the treatment of parasites on grazing animals. the purpose of the present study was to evaluate the anthelmintic effect of five tropical native australian plant species rich in plant secondary metabolites on adult haemonchus contortus and trichostrongylus colubriformis in experimentally infected goats. thirty young, nematode-free goats were infected with 2500 h. conto ...201222265804
the relative contributions of t. colubriformis, t. vitrinus, t. axei and t. rugatus to sheep infected with trichostrongylus spp. on the northern tablelands of new south wales.this survey was designed to determine the spatial and temporal distribution and the relative contributions of trichostrongylus colubriformis, trichostrongylus vitrinus, trichostrongylus axei and trichostrongylus rugatus to sheep infected with trichostrongylus spp. on the northern tablelands of nsw. thirty completed larval cultures were collected from a commercial parasitology laboratory servicing the northern tablelands of nsw between june and december 2007. cultures were selected at random from ...200919632782
availability of gastro-intestinal nematode larvae to sheep following winter contamination of pasture with six nematode species on the northern tablelands of new south wales.this experiment was designed to determine the infective consequences of winter pasture contamination by sheep infected with 6 species of trichostrongylid gastro-intestinal nematode (gin) at armidale in the new england region of nsw. ten helminthologically inert pasture plots were contaminated using 'donor' sheep harbouring artificial infections of haemonchus contortus, trichostrongylus colubriformis, trichostrongylus vitrinus, trichostrongylus axei, nematodirus spathiger and teladorsagia circumc ...200919070435
dietary protein for young grazing sheep: interactions with gastrointestinal parasitism.effects of protein supplementation and of nematode control on production responses in young grazing sheep and on nematode population dynamics were assessed. young merino wether sheep (n = 270) were allocated to one of three supplementation (su) treatments and one of three regimes of nematode control (drench, dr) in a factorial design. each of the nine treatments was replicated three times in a randomised complete block. animals received no supplement (su0) or were given supplements at a level eq ...19958747911
no loss of production due to larval challenge in sheep given continuous anthelmintic treatment via a controlled release capsule.this study aimed to quantify production loss due to larval challenge in sheep administered a controlled release albendazole capsule (crc) and thus determine the suitability of crc treated sheep as a proxy for worm-free sheep in grazing experiments. the experiment used an incomplete 2+ù3 latin square design with 81 merino wethers. sheep were either infected (inf) with mixed oral infection of albendazole-susceptible haemonchus contortus, trichostrongylus colubriformis, and teladorsagia circumcinct ...201121824729
