Abstract

In Louisiana, USA, post-mortem worm counts on the abomasa of 7 yearling beef steers in early February (1977) revealed from 5,000 to 20,000 Ostertagia ostertagi/steer of which 13.7 to 51.6% (average 36.2%) were inhibited (early 4th-stage) larvae. In controlled tests at the end of February...

Abstract

The efficacy of albendazole in removing gastrointestinal nematodes and tapeworms was studied in 16 treated and 16 untreated (control) beef calves. It was administered as an oral drench at 5 ml/45.5 kg of body weight (5 mg/kg). Percentage of efficacy against the various genera was: Trichostrongylus...

Abstract

Oxibendazole was given to 12 cattle naturally infected with gastro-intestinal helminths as a feed premix (mixed with 0.45 kg of a commercial ration) at a single dosage of 15 mg/kg. The treated and 12 control cattle were slaughtered 7 days after treatment. Based on the numbers of worms recovered the ...

Abstract

In northwest Louisiana, USA, beginning in November 1977 two or 3 cattle were removed each month from a grazing herd and examined post-mortem to find out when inhibited 4th-stage larvae of Ostertagia ostertagi were most numerous. Peak worm populations (50 000 to 100 000/animal) were discovered in...

Abstract

Albendazole, as a paste formulation, was evaluated for its efficacy against inhibited early fourth stage larvae of Ostertagia ostertagi in naturally infected, yearling beef cattle in April. The mean number of inhibited larvae in 11 untreated control cattle was 107,166. At the dosage level of 7.5 mg ...

Abstract

In Louisiana, USA, 2 yearling cattle were removed from pasture in late January, 2 in early February and 3 in early March. All were held in drylot for 2 or 3 weeks before slaughter. Ostertagia ostertagi worm burdens of those removed in January and February were similar but in the February group the...

Abstract

At 3 locations in Louisiana, USA, naturally infected yearling cattle were killed monthly over a 3-year period (1977-80) for worm counts. At 2 of the locations in 1978-79 tracer calves were grazed for monthly periods from late autumn to summer and these were also killed for worm counts. Ostertagia...

Abstract

This review pays special attention to Ostertagia ostertagi, but also mentions Haemonchus, Trichostrongylus and other genera of lesser importance in North America. The anthelmintics currently available in USA are coumaphos, haloxon, levamisole, phenothiazine, thiabendazole and morantel tartrate....

Abstract

The features of pre-type II and type II ostertagiasis in cattle are briefly described and compared with those of Menetrier's disease in man. It is considered that the elucidation of the mechanisms of irritation and the probable role of the immune system in ostertagiasis could produce useful...
