Over the last week or so, weโve done several FEC (faecal egg count) samples from ewes that have shown higher worm burdens than we would normally expect to see at marking time.
In a more โtypicalโ year, we wouldnโt usually expect ewes to need much attention for worms around now. However, this season has been a bit different. The very wet winter followed by a cold spring seems to have made things harder on many ewes going into lambing, which may have knocked their immunity a wee bit.
Around lambing time, ewes are already under a lot of pressure physically, and with grass growth being slower and poorer than usual this year, nutrition may not be quite where weโd like it to be. Ewes are also grazing much closer to the ground, which can mean picking up more worm larvae from the pasture.
Because of this, we would encourage people to keep an eye on their ewes around marking time and consider doing some FEC sampling before deciding whether a worm drench is needed.
We wouldnโt recommend routine worming of ewes as a standard approach, but this year may be one where checking first with a FEC could be particularly worthwhile. For lambs, we still recommend keeping an eye on the Nematodirus forecast in the next few weeks.
As always, if youโd like to chat things through or arrange some samples, just get in touch ๐
