Abstract

The effect of an ivermectin sustained-release bolus (I-SRB) on the epidemiology of nematode parasites and on calf productivity was evaluated in a field trial under Northwestern European conditions. 20 parasite-naive female Friesian calves (principals) aged 5-9 months were used together with 6 male...

Abstract

Chemoprophylaxis with an ivermectin sustained-release bolus in the first grazing season on the resistance of cattle to gastrointestinal nematodes during the following grazing season was investigated. In 1993 and 1994 dairy replacement calves were either given one bolus at the start of their first...

Abstract

Cellular and humoral immune responses of beef (Belgian White and Blue, BWB) and dairy (Friesian-Holstein, FH) cattle to P. ovis infestation were compared and the effects of P. ovis infestation on the immune responses to infectious bovine rhinotracheitis virus [bovine herpesvirus 1] (IBR) vaccine or ...

Abstract

Thirty parasite-naive Holstein-cross heifers aged 7 to 12 months were allocated into 3 groups and were treated with either an oxfendazole pulse release bolus (Repidose) administered orally at turnout or ivermectin (Ivomec) injected s.c. at 200 µg/kg at 3, 8 and 13 weeks after turnout or untreated...

Abstract

A sandwich ELISA was developed using polyclonal antibodies from P. cuniculi-infested rabbits and a crude P. cuniculi antigen. Sera from 133 P. ovis-infested and 137 uninfested cattle were serially diluted from 1:100 to 1:102 400 and analysed. Curves obtained by plotting log dilution versus optical...

Abstract

The epidemiology of gastrointestinal helminth infections in beef cows and calves on pasture was studied in Belgium during the 1990 and 1992 grazing seasons. Weight gain, faecal egg counts, generic differentiation of infective larvae, serum pepsinogen levels, herbage larval counts and worm burdens...

Abstract

Two outbreaks of parasitic gastroenteritis were observed in a group of 10 first-season grazing calves, one in mid-July and one in mid-September. In both cases emergency anthelmintic treatment was needed to prevent further damage. Severe clinical signs were observed together with high faecal egg...

Abstract

In 2 experiments, groups of calves were exposed to different levels and patterns of infection with Ostertagia spp. and Cooperia spp. The experimental design simulated the stereotypic pattern of herbage infestation, including a normal or a delayed midsummer increase, under conditions of...
