Abstract

Eprinomectin has been approved for use as a topically applied endectocide for beef and dairy cattle. To determine if eprinomectin has utility as an injectable anthelmintic, it was titrated at 0.05, 0.1, and 0.2 mg/kg s.c. against adult (Trial 1) and at 0.05, 0.1, 0.14, and 0.2 mg/kg s.c. against...

Abstract

62 naturally parasitized beef mixed-breed or Holstein cattle, either 6 to 11 or 48 to 96 months old, were used to assess the efficacy of eprinomectin at 4 geographic locations in the USA (1 each in Arkansas and Idaho and 2 in Missouri) in 1994. Cattle were housed 21 to 27 days before treatment to...

Abstract

Of 16 naturally infected cattle aged 10-12 months, not previously wormed, 8 were treated with 500 µg/g ivermectin pour-on. Faecal examinations, and PM examinations on days 9-10, revealed 100% efficacy against Haemonchus placei, Oesophagostomum radiatum, O. venulosum and Dictyocaulus viviparus, over ...

Abstract

Eprinomectin (MK-397 or 4″-epi-acetylamino-4″-deoxy-avermectin B1) is a novel avermectin selected for development as a topical endectocide for all cattle, including lactating dairy cows. To determine its anthelmintic capabilities, eprinomectin was tested topically on Jersey calves at 0.08, 0.2 or...
