Abstract

The study was carried out on faecal samples, both in 1968 on 688 animals, and in 1972 on 562 animals from the same area. In 1968 64% of the cattle were affected, and, in 1972, 44%. In descending order of frequency, species found were: Ostertagia, Haemonchus, Oesophagostomum, Trichostrongylus,...

Abstract

Ostertagia ostertagi was found in the abomasum of 45 of 99 cows (8-10 years of age) slaughtered at Milan and Paullo abattoirs between December, 1983 and April, 1985. The abomasum of a few of these 45 also contained Ostertagia lyrata and Trichostrongylus axei. The mean serum pepsinogen value of...

Abstract

Between December 1983 and April 1985, abomasa were examined from 147 cattle slaughtered in Milan, Italy; 67 (45.6%) were infected with nematodes. Parasite burdens were ≥2000 in >75% of cattle and the overall mean 2535/animal. Ostertagia ostertagi was present in all cattle. Serum pepsinogen levels...

Abstract

Samples of faeces were obtained from two groups of 30 and 40 cattle, infected with a range of gastro-intestinal nematodes, at intervals up to 15 days after administration of albendazole at 7.5 mg/kg. Most cattle stopped discharging helminth eggs by 24 h. The drug was effective against Ostertagia,...

Abstract

Blood was taken from 46 cows, just before slaughter, for determination of the mineral content, and their abomasa examined for parasites. No evidence of interference by parasites in the metabolism of Na, K, Ca, Mg or Cu was obtained, but there was a suggestion that increasing parasitism might lead...

Abstract

Measurement of antibodies to Ostertagia ostertagi in bulk tank milk (BTM) has value as a diagnostic indicator for potential production losses and anthelmintic treatment responses in dairy herds. Most of the recent data on O. ostertagi antibodies in milk have been generated in Belgium and Canada;...
