Confirmed Cases

The SCOPS Nematodirus Forecast is based on temperature data from 140 weather stations across the UK. It is a vital tool to help farmers, vets and advisors predict when nematodirus pose a risk to lambs. However, nematodirus eggs can hatch early in warmer, more sheltered fields and it is important to take into account potential variations from field to field and farm to farm.

When deciding whether or not to act, it is important to assess the risk to each group of lambs based on the history of the field and its aspect and altitude. South-facing fields tend to have an earlier hatch and, as a guide, every 100m increase in altitude will delay hatching by about seven days. So, for example, if the nearest weather station on the map is at 200m above sea level and the farm 100m above sea level, hatching could be around seven days earlier than the forecast.

The cases below are incidents where nematodirus has been confirmed on a farm before the area was highlighted as high risk on the SCOPS map - and are intended as an additional tool to be used alongside the SCOPS map. If you have experience a case of nematodirus before your area was highlighted as high risk on the map, please help SCOPS build a better picture of the challenge this year by completing this very short survey to report a confirmed case.
