Sentence examples for ewe egg from inspiring English sources

In flocks which lambed before the main lambing season in spring, the ewe egg counts remained very low (less than 100 epg) until the spring lambing period.

There was a high correlation between the magnitude of ewe egg output in spring and lamb egg output later in the season, indicating a direct relationship between the degree of pasture contamination and subsequent levels of larval availability.

If moving and weaning coincide or lambs at weaning are moved a second time to clean pasture, the ewes' egg output will not contribute to the increase in pasture contamination in late season and better control is likely to be achieved to avoid the late cases of diarrhoea and high numbers of immature nematodes.

Herbage infectivity of Ostertagia/Trichostrongylus remained very low in the paddocks of both treated groups throughout the season, apart from a brief increase in July on the set-stocked paddock (A), probably derived from the ewes' egg output in May-June.

Required input data included ewe parasite egg output, pasture-related information and management dynamics.

Thus there is an important seasonal component, whereby the post-parturient rise in ewe faecal egg counts is indeed a "spring rise" phenomena in Sweden.

Subsequently, the ewe faecal egg counts remained low at the second sampling, but showing a modest rise after 1 month on pasture.

In accordance with the policy of the Swedish Animal Health Service, owners of any flocks that had a positive ewe faecal egg count for H. contortus at the spring sampling, were recommended to treat all their ewes with an anthelmintic.

Therefore, with the ewe faecal egg counts being so low during the first 6 weeks following turn-out, the feeding of fungal material at this time (with the aim of reducing the number of infective larvae originating from this contamination in the latter part of the grazing season) could, in retrospect, reasonably be considered to have been of limited value.

Pre-experimental sampling (6 May) of ewes on farm L, showed that the majority of ewes (9/16) had egg counts less than 50 epg, however 3 ewes had egg counts exceeding 1,000 epg, which were shown by larval differential to be predominantly H. contortus.

Dolly, born in July 1996, was created when Ian Wilmut, Keith Campbell, and their colleagues inserted the nucleus of a mammary cell taken from a 6-year-old ewe into an egg cell from which the nucleus had been removed.
