Efficacy of febantel against naturally acquired gastrointestinal nematodes in calves, and recognition of Oesophagostomum venulosum in Oregon cattle.

The efficacy of febantel (5.0 mg/kg) against naturally acquired infections of gastrointestinal nematodes was evaluated in a controlled test in calves during the winter. Twenty steers were allotted to either control or treatment groups of 10 animals each.

Serum proteins of neonatal pigs orally inoculated with Isospora suis oocysts.

Serum proteins were evaluated by agarose electrophoresis at periodic intervals between postinoculation days (PID) 2 and 35 in 4 litters of pigs inoculated orally at 36 to 38 hours of age with 70,000 sporulated Isospora suis oocysts and in 4 litters of age-matched noninoculated control pigs. In inoculated pigs, clinical disease characterized by vomiting and diarrhea began at PID 3 to 4 and was resolved by PID 11. Isospora suis oocysts were detected in feces of inoculated pigs from PID 5 to 25, with peak numbers present on PID 5 to 6.

The anthelmintic efficacy of netobimin against naturally acquired gastrointestinal nematodes in sheep.

The broad-spectrum anthelmintic efficacy of netobimin (SCH 32481, Schering Corporation) was evaluated using 30 cross-bred spring lambs with naturally acquired infections of gastrointestinal nematodes. Three groups of 10 animals each were allotted into either control (given a tap water drench as a placebo) or 7.5 and 20 mg kg-1 dosage groups (given the netobimin as an oral drench).

Anthelmintic efficacy of netobimin against naturally acquired gastrointestinal nematodes in yearling heifers.

The efficacy of netobimin (Coded SCH 32481, Schering Corporation) in removing naturally acquired gastrointestinal nematode infections was evaluated in 10 treated and 10 untreated (control) yearling beef heifers. The anthelmintic was administered as an oral drench at a dose level of 7.5 mg kg-1 body weight.

The anthelmintic efficacy of netobimin against experimental infections of Fasciola hepatica in sheep.

Netobimin (coded SCH 32481, Schering Corporation), a new broad-spectrum anthelmintic having both fasciolicidal and nematocidal properties was evaluated for efficacy against mature Fasciola hepatica infections in sheep. The trial was conducted with 30 cross-bred spring lambs, each experimentally infected with 250 F. hepatica metacercariae.
