Abstract

Samples of slurry produced by young cattle in Ireland were collected between spring 1976 and spring 1978 from over 100 farms. Viable eggs (mainly Ostertagia ostertagi and Cooperia oncophora) were present in 87% of slurries that had accumulated under slatted floor housing units and that were sampled ...

Abstract

Calves treated at turnout with a bolus which slowly releases fenbendazole and untreated control calves were grazed in separate, adjoining plots from late April to mid-October. At the outset, the pasture of both plots was seeded with the lungworm, Dictyocaulus viviparus, and had a natural residual...

Abstract

In 2 successive years calves were grazed on pasture (A) which had in spring received slurry containing trichostrongylid eggs or on an adjacent pasture (B) that had not received slurry. In the first year pasture larval counts were higher on pasture A and the calves on this pasture had consistently...

Abstract

During their first grazing season one group of calves (group E) which had an oxfendazole pulse release bolus (OPRB) administered at turn out in April experienced only a mild degree of parasitic bronchitis when exposed to Dictyocaulus viviparus infection (introduced by seeder calves) in June...

Abstract

One group of first-season calves was dosed with an oxfendazole pulse release bolus at spring turnout (April 30), and on July 15 a second group received the front-loaded oxfendazole pulse release bolus. The objective was to test the boluses for the prophylaxis or control of nematodiasis. The control ...

Abstract

Reduced trichostrongylid infection on herbage and in calves was obtained when first-season calves, grazing a common area of pasture, received low-dosage phenothiazine (PTZ) in two successive years. The average daily dose of PTZ was 7 or 10.3 mg/kg in the first year and in the second, between 5 and...

Abstract

The efficacy of netobimin at daily dose rates of 1.5 mg/kg and 2.8 mg/kg and that of oxfendazole at 1 mg/kg daily when administered to calves in drinking water over a 7 day period, were compared. The calves, weighing approximately 118 kg, were artificially infected with Ostertagia and Cooperia...

Abstract

The anthelmintic Netobimin was given orally to calves at a dosage of 7.5 mg/kg body weight at three and six weeks after spring turnout (May 7). Pasture grazed by control calves showed a great increase in trichostrongylid infection in mid-August, while the numbers of infective larvae (L3) on the...

Abstract

Several anthelmintics suppressed the output of Ostertagia ostertagi and Cooperia oncophora eggs and Dictyocaulus viviparus larvae when administered at low dosage in the drinking water to artificially infected calves kept indoors. Under grazing conditions, morantel, levamisole and oxfendazole...
