3 weeks after they go to grass.
5 weeks then after.
Using ivomec super

greysides

When Ivomec first came out a 3,8,13 weeks at grass strategy was recommended. Where calves were set-stocked this was meant to suffice for the whole grazing season as the early hammering of the worms would mean that there was little left to cause problems later.
When Dectomax came out with it's longer period of inhibition a 0,8 week recommendation for set-stocking came with it.

we normally dose when they start coughing

onyerbikepat

With the suckler spring calves. I normally do first time in mid June or thereabouts. This year I didnt do them till a week ago and none had showed any signs of coughing yet. Down to the fine year, I guess.

have always done it that way here, maybe we are wrong but why dose if there isnt a problem, is it not a treatment not a preventative

well im just asking cos i had to get injections for cattle 1 year to clear up coughing, vet said i hadn't dosed on time. anyways when something works well for you there is the golden rule "if it aint broken why fix it"

wouldn't worry about young stock getting slight hoose, it helps to build up immunity for later on

unnecessary dosing with with ivomec type means calves dont build up self immunity

levacide is the best dose if animals are coughing badly , it kills the worms slowly thus lowering the risk of virus or hoose related pneumonia


anyhow to answer op we dosed about 6 weeks after turn out with levacide,
again with albex about 6 weeks further on ,

the calves are getting fresh aftergrass every 2 to 3 weeks now so hopefully shouldnt require dosing until after winter housing

6-8 weeks from turn out with albex here too.

Sorry to disagree but Levacide kills the worms so quickly it can be used as a diagnostic test. Within a sort period of time they'll be coughing worse, coughing up the dead worms..... or so my source in the Regional Vet Lab tells me.

For slow kills, it's a toss up between a white dose and an avermectin. A white dose would get my vote but MSD claims ivomec will work slowly too.

I used levicide injection month ago when the calves started coughing. It'll be paramectin injection every six weeks from now on. Was talking to my vet of thirty years experience last week about worms in calves etc. and he said that levicide kills the worms slowly over thirty days whereas paramectin kills them all in one go.
If anyone is using levicide pour on, be very careful not to overdose calves with it. A farmer put ten times the recomended dose on his calves and they started staggering around the yard. Only he had a power hose handy to wash it off, he could have lost them.

Speed of action of some anthelmintics against Dictyocaulus viviparus infection in cattle- GA Oakley


Abstract

In a study of the comparative speed of action of anthelmintics against Dictyocaulus viviparus infection in cattle levamisole reduced the lungworm burdens by 87 per cent within three hours of administration whereas fenbendazole and febantel required 36 hours to achieve 80 and 87 per cent reduction, respectively. The more rapid action of levamisole may be advantageous in the treatment of bovine parasitic bronchitis since it allows virtually immediate elimination of the majority of the lungworms and limits undesirable sequelae dependent on the continued presence of the parasite.

just realized that dosing with ivomec or similar did cause a problem for me when in dairy stock about 6 years ago vet mentioned about inability to build up immunity due to overkill,had to worm cows with a bolus(non milk withdrawal type) once a year for 2 years (scouring),use pour-on closamectin (i think, in yellow carton)
covers lungworms fluke, i have wet ground. used with 3 years now and no problems since, barring stomach problems so advised to give milk in bottle with teat before bucket feeding (just for week or so)to overcome this,vet said it gets stomach working properly,changing to milk replacer didn't work. but that's off topic here.so dosing at 6 weeks after turnout now and in sept weather depending. no fluke in cattle going to factory and no coughs either.
