Abstract

The objectives of this study were (1) to determine the effect of a treatment with eprinomectin in autumn of pastured dairy herds on the anti-Ostertagia ostertagi bulk-tank milk antibody level, (2) to determine the overall effect of this treatment on three milk-production parameters (milk yield,...

Abstract

Our primary objective was to determine the relationships between Fasciola-specific antibody levels in bulk-tank milk and measures of productivity to estimate economic losses that are associated with Fasciola infections. A bulk-tank milk sample was collected in March 2004 from 1105 dairy herds in...

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;...

Abstract

Cooperia oncophora total adult extracts were examined by Western blotting with sera from C. oncophora- and Ostertagia ostertagi-infected calves to determine species-specific antigens. It was shown that 2 antigens with apparent MWs of 14 200 and 14 900 were only recognized by calves which received a ...

Abstract

Antigenic differences between the developmental stages of O. ostertagi were studied by SDS-PAGE and Western blotting. Gel electrophoresis showed a complex protein pattern different for every stage with the O. ostertagi fourth stage larvae (L4) showing an intermediate protein pattern between the...

Abstract

The persistent efficacies of doramectin and ivermectin injectable against moderate and high infection levels of Ostertagia ostertagi and Cooperia oncophora were evaluated in cattle. Calves were allocated to 6 groups of 6 animals. On Day 0 animals of Groups I1/I2 and D1/D2 were treated with 0.2...

Abstract

Of 1249 male cattle examined in the slaughterhouse at Kandy, Sri Lanka, during 1987, 40% were infected with M. laryngeus (range 34 to 52%). The infection rate was highest (47%) in 2- to 2.5-year-old animals. In infected animals an average of 6.4 parasite pairs was found with higher numbers in older ...

Abstract

Between February 1994 and March 1995, faecal and serum samples were collected monthly from Zebu cattle of 1 to 30 months old on 3 ranches (20-25 animals ranch-1 sample-1) in Mindanao, Philippines. On 2 of the ranches one ivermectin treatment was carried out during the experimental period....

Abstract

Estimation of serum pepsinogen concentration in cattle is used to aid the detection of clinical or subclinical infections with Ostertagia ostertagi. An inexpensive, simple micro method for the routine determination of pepsinogen concentration in bovine serum samples is described which is based on...
