Abstract

In Experiment 1 three groups of worm-free lambs were given 5000 Trichostrongylus colubriformis larvae daily for 23 days. Two groups were medicated in the food for 28 days with either 1.0 or 1.25 mg/kg/day morantel tartrate. The third group remained unmedicated as control. Post-mortem worm counts...

Abstract

Five controlled anthelmintic trials involving worm counts in 71 calves with experimental infections of gastrointestinal nematodes and lungworms were carried out using various dosages of morantal tartrate administered by drench. High activity (98-99%) was recorded against 14- and 21-day-old H....

Abstract

In England, in 1970, field trials involving 355 first year grazing calves on 10 farms were carried out; conditions of clinical infection with gastro-intestinal nematodes, mainly Ostertagia and Cooperia, were observed on 7 farms and parasitic bronchitis on 2 farms; one farm showed no symptoms of...

Abstract

Ten anthelmintic trials involving worm counts in 130 calves with experimental infections of gastro-intestinal nematodes and lungworms were carried out using combinations of morantel tartrate and diethylcarbamazine. High activity (95-100%) was recorded against seven, 14 and 21-day-old Haemonchus...

Abstract

Twenty-four castrated Friesian calves were divided into 2 equal groups on a body-weight basis and grazed separate halves of an infected pasture in England. One group was given 1.5 mg/kg per day morantel tartrate in the feed over a period extending from 2 weeks before turning out in early May to...

Abstract

Third-stage larvae were demonstrated, 14 hours after infection, in the lungs of gapes dosed with 4, 000 to 10, 000 normal D. viviparus. Development to the early fifth stage occurred, but the numbers of worms fell rapidly after day 10 and the infection was eliminated after 16 days. Immunisation with ...

Abstract

The epidemiology of parasitic gastroenteritis (p.g.e.) and incidental observations on lungworm infection were studied on two equal-sized paddocks (1.9 ha) of permanent pasture. Groups of 10 calves were exposed for the first time to each paddock in May and grazed until the end of October. Faeces...

Abstract

Infective lungworm larvae attenuated by exposure to 07% triethylene melamine (TEM) were capable of immunizing calves against experimental challenge. The calves were given two doses of 1, 000 attenuated larvae, 2 or 4 weeks apart. It compared well with X-irradiated larvae. In a field trial, calves...
