Worm Watch

It’s that time of year again: worm fecal egg counts are rising on our two sentinel farms.
June was very dry, and that will have held the larvae back (only 21 mm of rain on our farm for the month) but now that it’s wetter we can expect lots of infective larvae to move from the fecal pellets onto the grass. Very soon we’ll need to think about dosing: will the new wormer make a difference to my animals? Are my yearlings at risk if they stayed in the barn as lambs? Is my rotational grazing or co-grazing with cattle an effective strategy?

We are particularly interested in producers who plan to use Flukiver (closantel) this year: we would like to recruit participants, for at least 10 farms, to compare the results of using this wormer in a group of 10-15 lambs (or yearlings) with another group dosed with one of the regular wormers. What is the difference in worm egg counts? Is there an improvement in weight gain or FAMACHA score? These results can help all of us make the best use of the new wormer. Please help us if you can.

We are again offering free faecal egg counts and faecal egg count reduction tests (for wormer efficacy). Do you need to know the general worm burden in lambs on pasture? Would you like to monitor the flock through July and August? We can help: contact me at gjones(at)smu.ca or through SPANS (Brad McCallum, 902-893-7455) or Jonathan Wort at Perennia (902-896-0277).
