Effective gastrointestinal nematode management in livestock industries is becoming increasingly difficult due to the rise of anthelmintic resistance and changes temporal geographical distribution major nematodes. Underpinning response these challenges need for a fast-tracked diagnostic identification technique, making it easier producers make informed decisions. The traditional 'gold-standard' approach, larval culture followed by morphological differentiation, laborious potentially...
Anthelmintic-resistant parasitic nematodes present a significant threat to sustainable livestock production worldwide. The ability detect the emergence of anthelmintic resistance at an early stage, and therefore determine which drugs remain most effective, is crucial for minimising losses. Despite many years research into molecular basis resistance, no molecular-based tools are commercially available diagnosis as it emerges in field settings. We described mixed deep amplicon sequencing...
Gastrointestinal nematodes threaten the productivity of grazing livestock and anthelmintic resistance has emerged globally. It is broadly understood that wild ruminants living in sympatry with act as a positive source refugia for anthelmintic-susceptible nematodes. However, they might also reservoirs anthelmintic-resistant nematodes, contributing to spread at regional scale. Here, we sampled managed sheep cattle together feral goats within same property New South Wales, Australia. Internal...
Our understanding of anthelmintic resistance in the gastrointestinal nematodes Australian cattle relies exclusively on small-scale phenotypic reports utilising traditional faecal egg count reduction tests. This approach is not readily scalable to establish national prevalence resistance, nor it conducive routine longitudinal surveillance for emergence its early stages. study introduces benefits applying mixed amplicon metabarcoding longitudinally timely and cost-efficient molecular multiple...
Eucoleus aerophilus (syn. Capillaria aerophila) is a zoonotic trichuroid nematode parasite of dogs, cats and wild carnivores with global distribution. The main reservoir species in Europe the red fox, where it has been detected up to 97% animals surveyed. Despite burgeoning feral cat fox population Australia, there paucity information about occurrence molecular identity E. these species. gravid capillariid bronchoalveolar lavage 12-week-old kitten from central New South Wales (NSW), history...
Gastrointestinal nematodes are the most expensive agent of disease currently facing livestock production industry. Spending beginning their life cycle as eggs and free-living larvae, vulnerable to a multitude external environmental factors. Fire is naturally occurring force nature that has both destructive reconstructive effects on soil characteristics which nematode stages rely for survival. The aim this project was evaluate in vitro effect burned pasture (200 °C 500 °C) ruminant nematodes....

A field trial was conducted with 80 cow-calf pairs to evaluate the effect of deworming both cows and calves fenbendazole, on cattle performance internal parasite burden. Midseason weaning weights in fenbendazole-treated group averaged 22.4 33.5 lb heavier (P<.04), respectively, than controls. Cow calf fecal egg counts were low throughout grazing season not materially affected by treatment.
A trial was conducted to evaluate the influence of diet composition and type medication on pigs weaned at approximately 5 weeks age (average initial weight 15 pounds). commercial feeding program containing extruded full fat soybeans compared with a milo-soybean meal (19.2% protein 1.25% lysine) neomycin (150 grams per ton) or neoterramycin terramycin each ton). Pigs were fed treatments for 6 while in nursery. Performance monitored continuously market nursery overall growth carcass yield. The...
Twelve on-farm trials with a total of 1572 pigs were conducted to evaluate the effect Flavomycin in growing-finishing swine diets. In three twelve trials, average daily gain was increased (P<.06) and seven feed efficiency improved numerically over nonmedicated control other additives (Aureomycin, Tylan, Stafac, Pen-Strep, Lincomix). The percent improvement varied greatly by location trial.; Swine Day, Manhattan, KS, November 11, 1982
