Used them for years, had 60 First Grazer delivered today actually. Excellent for developing immunity, no negative affects on soil biology, unlike Ivomec type products, labour saving, tax allowable, apart from being a tad expensive, what’s not to like?
Used them once yonks ago when huskvac was unavailable for some reason.
Did the job but you couldn't half tell when they needed to pulse.
Haven't needed to use any wormer for years. Closed herd autumn bias bonus I guess.
What’s a closed herd got to do with worms? Surely you must worm your young stock ?
This is where we need to get to I think, never done a fec count but fairly sure they’d manage without being wormed, it’s the huskvac element we need to put into place for lungworm, had a mate have an awful do with it a few years ago, anybody know what it costs?
