Abstract：
:Twenty-four Holando Argentino male calves were treated orally with 50 mg/kg body weight trichlorphon (TCF); 0.2 mg/kg body weight subcutaneous ivermectin (IVM); a combination of TCF+IVM at the same doses and administration routes; or remained untreated (control group). All calves were necropsied at day 14 post treatment for counting and identification of worms from abomasum, small and large intestines and lungs to determine the absolute efficacy (controlled efficacy test) for each treatment. Using the faecal egg count reduction test, the efficacy was 63.7 % for TCF, 72.3 % for IVM and 99.2 % for TCF+IVM. The absolute efficacy of IVM and IVM+TCF was 100 % against Haemonchus placei, Trichostrongylus axei and Ostertagia ostertagi (p < 0.05). TCF showed a similar level of efficacy except against O. ostertagi (84.7 %). Efficacy of the treatments against Cooperia oncophora/pectinata/mcmasteri was 80.4 % for IVM, 95.7 % for TCF and 99.6 % for TCF+IVM; against Trichostrongylus colubriformis was 79 % for IVM, 86.2 % for TCF and 94.1 % for TCF+IVM; against Nematodirus helvetianus was 0 % for IVM, 100 % for TCF and 93.8 % for TCF+IVM. The efficacies of TCF, IVM and TCF+IVM were 100 % against Oesophagostomum radiatum and Trichuris spp. The efficacy of TCF against Dictyocaulus viviparus was 52 % and 100 % for IVM and IVM+TCF, respectively. This is the first report of Trichostrongylus colubriformis and Nematodirus helvetianus resistant to ivermectin treatment in cattle of Argentina. The TCF+IVM combination could be an alternative for the control and treatment of nematode infections including IVM-resistant strains.
