How fast does ivermectin work in cattle?

[TelesnaAg]

I have a tennant farmer, who os not a farmer by any stretch. Had 1 200kg angus hereford heifer here, was going backwards, so i cracked it and got it in and said im treating, another story.

Anyway i have the girl in the yards, called vet, gave ivermectin pour on, i would rather use injectible now. Anyway there is not much literature on how quick it works, the heifer "Betty" is spraying her poop, shes a mess.
I also gave multin min subcutaneous, and penicilin for respiratory and relief.
Shes on hay and lucerne hay in yards, she was very weak comibg out of paddock, fell over a couple of times, i walked her in on foot.
Shes better today, day 2. Eating and drinking. Cleared up in the eyes alot.
When in the crush i cleaned around her back end as skin was looking poor, she just stood there and didnt argue.
Will take a couple of goes to get her cleaned up.
Ive never let cattle get poor before.
So should i see a clumpy stool in 3,5,7,14 days??? Id class here infection of worms as severe.
Vet thinks 7 days should see a change, but peolle experience is the best measure.
Any nutritional things i should be doing? Shes off fresh grass which im not sure right or wrong to do? They all say dry hay.

Any stories of poor cattle peolle have turned around id love to hear.

Cheers, Ant

within a week it should work. have seen some cases of lice resistant to deltamethrin and cattle rubbing, dose of ivermectin and a week later cattle not rubbing.

If she is that poor she may suffer for a while longer as the worms die and release from the guts.

How is she now?

 

[upnortheast]

The worms will be killed within 48 hours. The problem will be how quickly the gut damage repairs. with the severe situation you describe could take a month before she turns around.
May benefit from the high energy drinks that are sold for new calved cows. this sort of thing https://www.gshepherdanimalhealth.c...thirst-fresh-cow-drink?sort=pd.name&order=ASC

Has the vet confirmed that Ivermectin is the appropriate anthelmintic for the parasites she hosts? It is not universal in its efficacy.

Seconded - do a FECRT to check.

Could be fluke - do they get that in Victoria?

 

[TelesnaAg]

Update, yes they get fluke in vic, but not around here.

Yes they tested poop, ivermectin was fine, on saturday she had an injectable of doramectin. Her egg count had come down from 1200 to 300, so this last drench should bout knacker them. Shes alot better but slow process, she's maintaining atleast, which is a good sign, id say 3 months until the gut really gets functional if ever, she is looked after like a sick cat here, so she is as comfortable as i can make her.

Ill get some update pics.

I will only use injectible drench in future.

This would have had a lot more replies if in livestock. Maybe a mod could move it
@Bald Rick
Let us know how she's doing

Well, it is now.

Betty is not keen at all on grain and even lucerne, like shes avoiding richer foods? She is eating plain hay and grass, not sure how to get more nutrients into her? Shes had multimin injection, cant go again for a month yet.

[wrenbird]

Maybe something sweet, perhaps with molasses in would tempt her? Perhaps it’s no bad thing for her to build herself up slowly without too much rich food all at once, her whole digestive system must be in a pretty delicate state still. Well done to you for doing your best for her, I hope she starts to show the benefit of your care soon.

Do you have a set of wild plants that sheep will nibble for self medication @TelesnaAg ?
As well as the hay and grass, is there something equivalent to (common here) bramble, hogweed, wilted stinging nettle that you can offer to help her diversify her gut flora after her treatment?

 

[Cowmansam]

Hays probably good enough something to rich will just scour her
