Fluke dosing

[Greythundercloudys]

I just done all of mine with a straight fluke dose and a straight wormer about 3 weeks ago, been very dry here till today, next one in January.

 

[Bury the Trash]

20% of our lamb livers spoilt by fluke in the last batch sent 3weeks ago, so since that ive dosed all the remainder with Flukiver as its got the lowest mwd and we need them gone before Christmas else we will run out of keep later.
Does haemonchus as well.

heck of a wet May here every day infact. milder now as well and generally milder winters

You need adult fluke to lay the eggs to get immature fluke... You will have adult fluke all summer - which is why Zanil and Albendazole are recommended for summer dosing as it is only adult fluke you are treating for.

You will have adult fluke almost year-round. But it is only in the Autumn to early spring you have all age groups (weather depending)

But the fluke cycle can go on for 6 months or more outside an animal, during which time there is no need for an adult, when they could have been cleaned out.

That depends when your last dose in the spring was

Most flocks will be carrying adult fluke over the summer (hence why @shearerlad vet told him to dose Supaverm (Closantel) in the summer at weaning to clear out more mature fluke.




As an aside, even this summer with the drought we had - the wet holes never baked out, the ground was still moist, so the mud snails survived in decent numbers (they also survived the very hard winter back in January and February - as it was neither cold enough or lasted long enough to kill), so soon as the rains came, and there's been plenty this past 3 months, they'll be active and ewes are hoovering up

Levafas Diamond has the shortest withdrawal period, but will only kill adult fluke. Withdrawal is only 5 days, which is shorter than the levamisole wormer that it also contains, for some unfathomable reason.

My point was that the fluke cycle isn't dependent on adults surviving the summer in an animal.

If that were the case we could wipe fluke in a season

No. But saying some doses will do nothing is still not correct, either.

They all have their place, as long as whoever is using them knows what that flukicide will do and what plan is needed (follow up doses etc) to get the desired effect in managing the fluke population

Some doses will do nothing, unless there is fluke present at a suitable age for them to kill.

generally they were looking ok outwardly, maybe stalling
was only the kill sheet that made me ut 2 and 2 together about a couple of unexplained deaths . Acute ?

have also put them over the weights so will see.
will be doing more to weighing next year
....., and maybe get a microscope...

I give my ewes flukiver or similar at time off flushing in September, will do same again next month and then again when thet get their booster pre lambing. They come inside mid December. Can’t use anything else as resistant to tricalbendazole badly

 

[Frank-the-Wool]

I'd agree, but it's surprising at how many don't realise that.
It will be down to how wet a summer you've had compared to normal

This is a dangerous assumption.
Our worst Fluke years in the south are after drought years as the sheep and cattle graze the areas on the edges of the dykes and along ponds where the mud snails live.
In normal grassy years it is seldom an issue at all except on some well known areas of low lying land.

I was speaking generally of course, and more water suits snails and larvae best.
Of course it's not just about snails it's got a lot to do with how it gets into the Ruminant and dry years don't suit that as wet grass is the main factor for ingestion.

Your own personal situation is individual to you, if you have water and wet grass all year round every year you're unlikely to have a year you're not bothered by fluke regardless of the summer.
But I struggle to understand how giving fluke a broader more suitable environment to thrive will add up to a better result in a wet year.

When you say a worse fluke years, how do you find it worse in dry conditions?
High levels of individual breakdowns and deaths or is the whole flock suffering or do you do faecal counts.

 

[Old Tip]

I kill sheep every week for the local butcher, not had one with any sign of fluke so far, we had an exeptionaly dry summer so expecting fluke to be low but usually have signs by now.
one of the near by farm vet groups did a test on twelve farms in 2019, they took blood samples monthly and alerted the farmer to start dosing when they identified any signs of fluke. Only two farms bedded to dose in December and half never needed to dose at all. These were all farms that had been dosing for fluke three to six times a year previousl, they saved hundreds in dosing plus time, labour and retention.
The days of doing it because your dad or neighbours do it are gone there is many more tools now to guide us

wasnt thinking straight , it was actually 20 condemned livers (fluke) in a batch of 50

but we're in the sunny SW yes

very dry could focus the stock into drinking or grazing on or near wet holes that they wouildnt normally go to because theyre not that desperate usually. ?

of course we know proper water drinker s can be supplied for sheep but they often dont bother with it all cattle are a bit different.

Fluke with us is not normally a problem, even though we are on what is known as a Marsh, with low lying areas that are wet in the winter and all border dykes around relatively small fields.
Fluke only becomes a significant problem in drought years as sheep and cattle rend to graze into the dykes where the mud snails live.

Funnily we have some wet areas, but only see fluke activity in wet years, in dry years there is always pretty much zero evidence.

To be fair, I would expect your ‘dry’ years to still be considerably wetter than a dry summer in Kent.

We're about 30 inches

Are sure it was fluke, could have dog worm cysts or was the info clear it was definitely fluke
