Abstract

The persistent anthelmintic effect of ivermectin as a topical treatment at 500 µg/kg was evaluated against induced infections of Ostertagia ostertagi, Trichostrongylus axei and Dictyocaulus viviparus in eighteen 2 to 3 month old calves. The results showed a highly significant anthelmintic activity...

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

Two groups, each of 7 naturally infected calves, were given single oral dose of 10 or 25 mg/kg closantel and, along with 7 controls, killed after 7 days. PM worm counts, after artificial digestion of abomasum and small intestine, revealed high efficiency against adult and immature Haemonchus...

Abstract

Levamisole (pour-on) was applied to the lumbar region of 161 cattle at 10 mg/kg body-weight (no dose exceeded 45 ml of the 10% solution). The drug was 98.05% effective against gastro-intestinal strongyles, as shown by faecal examination 5 days after treatment. Further trials using smaller numbers...

Abstract

Three-month-old calves were experimentally infected, in 8 groups of 4, with 8000 infective larvae of Dictyocaulus viviparus. A 9th group remained uninfected. The next day, groups 1 and 2 were treated with levamisole (7.5 mg/kg subcutaneously), groups 3 and 4 with oxfendazole (5 mg/kg orally) and...

Abstract

Two formulations of avermectin B1a, C-076 and MK-933, were examined for anthelmintic activity in two trials, each using 20 calves with experimental nematode infections. In one trial, C-076 was given orally, and in the other trial, MK-933 was given by injection at dosages of 50, 100, and 200 mu...

Abstract

In the Piedmont area of Italy, naturally infected lambs were treated with oxfendazole suspension (5 mg/kg) which, judging by worm counts on treated and untreated animals after 11 days, completely eliminated Ostertagia spp., Trichostrongylus axei, Haemonchus contortus, Nematodirus spp., intestinal...

Abstract

Paraherquamide, an oxindole alkaloid metabolite of Penicillium paraherquei and Penicillium charlesii, was tested against the adult stages of 9 common gastrointestinal and lung nematodes of calves at single, oral dosages of 0.5, 1.0, 2.0 or 4.0 mg/kg. At dosages of 1.0-4.0 mg/kg there was 95% or...

Abstract

Four experiments in 1978-79, and two in 1982 designed to define the optimum dose rate of dermally applied formulations of levamisole are described. These experiments showed that the absorption of levamisole with resultant blood levels and anthelmintic activity is strongly influenced by temperature. ...

Abstract

In 5 trials, in which 115 artificially infected calves were used, larval anthelmintic tests were done to assess the activity of oxfendazole at 4.5 mg/kg against all 3 parasitic stages of 6 species of nematodes. An efficacy of over 98% was demonstrated against 4th-stage larvae (L4), 5th and adult...
