Is it too early for lungworm ?

[Water Wheel]

Milked at weekend and this morning, a few cows are coughing, perhaps 1 in 15 ( a row)
It seems too early to be thinking of lungworm , but is it ?
We have been grazing since mid March, and had a bad attack last year, so I suppose could have a high burden of infection.
We treated them 3 times in total last year, I think ! We thought one treatment had failed completly.

Maybe a bit of lung damage from last year. Suppose there’s been enough heat, I don’t think there’s a line or a date when to worm grazers, when enough start coughing I order the wormer

Should be some resistance if there was plenty last year, apart from new herd members?

Thats what I thougth.
Thought the same last year, but that was a faliure!
Went 30 years without worming any adults , now seems an annual event

If it sorted em last year then it's a fair assumption to go again, there's supposed to be a payback in milk for controlling regular worms to cover the hassle. We tend to just do 1st lactation if any, but nothing routine.

We started using huskvac on the yearlings because we were having to treat the milkers up to 3 time’s a year.
The huskvac works, we haven’t had to use any pour in on the milkers for the last 2 seasons

Interesting.
We stopped using huskvac on first season grazing calves 6 or 7 years ago. Now we have trouble in milkers , but not youngstock.
Suggests huskvac is giving better immunity than natural infection, which seems odd, but privious infection in the cows dosen't seem to be doing the job.

We stopped using huskvac about 15 years ago. We started using it again 4 years ago because we seemed to be treating the milking herd almost constantly through the grazing season. They just didn’t seem to be getting natural immunity anymore

I was on a Webex meeting on lungworm and a vet suggested because of the unseasonable early hot weather the lungworm spores in the dungpats weren’t spreading because there was no moisture. Then the rain came and the spores have spread, I’ve had at least 15 of my customers have confirmed lungworm already in the past 2 months where usually it’s not present until sept/Oct.

We have dung sampled calves, very little in way of lung or gut worms but a raised level of cocci. No clinical signs though.

Historically seen out break of LW in July.

 

[I thats it]

Did our milkers yesterday

Don’t understand why more people don’t use husvac it saves getting infected cows and then having to use wormer.

We lost "Huskvac'd" calves mid summer.
Don't see home bred cows with a "cough"

Very quick PM on an in calf heifer. She had eprinomectin 40 days before this infestation.

Sorry but what are we looking at?

Lungworm in one that went downhill very quick, the vet cut open the trachea and worms and a right load of bloody crap came out. Theoretically she was only 12 days past being protected by the wormer. I say theoretically because there is variation in efficacy across individuals.
