| strains of cattle parasites in the netherlands with different propensities for inhibited development. | a field study was undertaken of the possible differences in propensity for inhibited development in strains of cattle nematodes from two different locations in the netherlands. in one location (lelystad) the strains were thought to lack the ability for inhibited development as a result of environmental stimuli on the infective larvae, while in the other location (utrecht) this ability was presumed to be present. the lelystad strains were kept at the original location and were also transferred to ... | 1987 | 3590614 |
| exposure of dairy cows to nematode infections at the end of the grazing season in the netherlands. | in autumn 2000, a study was carried out on 25 dairy farms in the vicinity of utrecht with the aim to estimate infectivity levels for nematode parasites in cows. on each farm, faecal samples were collected from 15 cows, blood samples from 5 of these and herbage samples from 2 cow pastures. faecal examination demonstrated a variation between farms and within farms in faecal egg output with a mean number of 4 eggs/g faeces (epg) and ostertagia spp. and cooperia oncophora being the dominant species. ... | 2002 | 12446093 |
