2015 Barberpole Worm Project- Invite to Participate

We’re getting the parasite project under way again for this year. There are several things we’re planning to follow:

• The rise in fecal egg counts from now to the end of July: when does the danger period start?

To see how soon and how fast the counts are rising, we would like to have counts done on some lambs on pasture at 2-week intervals over the next few weeks. Our animals went out to pasture on May 15, and the lambs’ counts are rising now; so far, about the same time frame as last year but the counts are higher, as high they were in 2013. We would like to follow a group of 10-15 animals per farm, either lambs or yearlings if they are in their first grazing season.

• Fecal egg count reduction tests, to see how effective your wormer(s) is/are.

• Sampling to select for more resistant lambs (probably September/October)

• Usefulness of different grazing practices. We are looking for any examples of grazing management for lambs or yearlings, such as:-
– rotational grazing,
-grazing with cattle or horses,
– weaning lambs onto separate pasture or into the barn,
– increased clover/birdsfoot trefoil for grazing lambs,
– targeted selective treatment (dosing based on eyelid colour or weight gain),
– as well as farms where lambs graze with ewes all season on the same pasture.

We’re looking to follow a group of 10-15 lambs per farm, to see what effect, if any, your management practices have had on egg counts, anthelmintic use, and/or weight gain: essentially, to demonstrate how different farms are dealing with the Barberpole issue.

This would not need many sampling periods, maybe early, mid- and late-season
We can usually provide some sampling assistance, if needed.

If you have any interest in monitoring the animals on your farm, please let us know how we can help.
