Background: Gastrointestinal nematodes (GINs) can cause significant economic losses in alpacas due to lowered production of fibre and meat. Although no anthelmintics are registered for use in alpacas, various classes of anthelmintics are frequently used to control parasitic gastroenteritis in...

The epidemiology and the effect on live weight gain (LWG) of internal parasites was studied on weaned heifers from May to December during 1990 and 1991. In each period 2 groups of 20 calves were chosen at random and grazed the same natural pasture. The stocking rates were 1 head/3.5 ha (1990) and 1 ...

Two studies were performed to investigate the efficacy of doramectin in the prevention of infection with Ostertagia ostertagi and Cooperia oncophora in grazing calves. In each study 24 parasite-naive calves were randomly allotted to 2 equal groups and treated with either doramectin at 200 µg/kg or...
