Abstract

Two studies demonstrated the persistent activity of ivermectin injected subcutaneously into cattle at 200 µg/kg in preventing the establishment of induced infections with Ostertagia ostertagi, Cooperia oncophora and Dictyocaulus viviparus. There were reductions in mean worm count (compared with the ...

Abstract

Comparisons were made of the effects of different early season anthelmintics on Dictyocaulus viviparus and Osteragia ostertagi. Estimated worm burdens indicated that oxfendazole resulted in a 78.1% reduction of O. ostertagi and 84.4% of D. viviparus, produced a 94.3% reduction in O. ostertagi and...

Abstract

In vivo measurements of total body water, exchangeable sodium and exchangeable potassium, were made by radioisotopic dilution techniques, in 20 calves exposed to natural infections with Ostertagia ostertagi, Cooperia oncophora, and Nematodirus battus during their first grazing season. Ten calves...

Abstract

Calves which grazed from October 7, 1977, pasture infested with larvae of Ostertagia ostertagi and other gastro-intestinal nematodes were treated on November 8 (after housing for 6 days) or on January 4 (after housing for one month) with fenbendazole at 7.5 mg/kg body-weight. Autopsy worm counts 8...

Abstract

Eight 9 to 12-month-old calves were allowed to graze pasture heavily infested with Ostertagia ostertagi larvae from October 18 to November 12. The calves were then housed and after 10 days half were given fenbendazole (840 g/ton) in a feedblock for 10 days (dosage 1.0 mg/kg body-weight/day)....

Abstract

On 9 farms in north-west England adult winter-calving dairy cows were treated in the dry period (November) with fenbendazole at 7.5 mg/kg body-weight. Comparison of treated and control cows with regard to the difference in milk yields between the lactations before and after treatment showed an...

Abstract

Observations of growth, nitrogen (N) balance and digestibility were made during the first winter housing period on 3 groups of calves which had previously been naturally infected with Ostertagia ostertagi and which were left either untreated (A) or treated with fenbendazole on 3 occasions (B) or...

Abstract

Fenbendazole was administered in January or February at 7.5 mg/kg body-weight to calves infected with Ostertagia ostertagi and Cooperia oncophora. The infections had been acquired in various ways: by grazing (in November and December) naturally contaminated pasture; by grazing (in December) pasture ...
