Older Cow - Worms

onyerbikepat

I did a 6 year old cow with Noromectin Pour-On there about a week ago.
She was in the yard at the time with the calves I was doing for worms. She was very scoury so I said what the heck, can't do any harm.

Scour is well gone now, so question is - Could she have worms at that age?
You would expect she would have good immunity by now. She is homebred aswell and was dosed as a calf during the first year.
If not worms, what else could it be?

old cows/cattle can have worms.if dried-up in scour that was probably what she had..i don't think you would be wasting money by giving your year and half olds a dose either

All cows here get dosed here at drying and calving again.. Heifers get a dose every few weeks too

Had one I kept dosing and she would dry up a bit then start it all again . I got her tested for johnes and it proved positive. It's not a dear test if the vets in the yard

would ya need to do your heifers that often greengrass,would they not have a level of immunity built up from the first year

Had trouble with worms in cows and had poor thrive with heifers so just as easy do them now. They might get done 3 times in the yr

Scour and rapid weight loss and in the later stages a lump under there jaw, no cure on the hook if they aren't to skinny.if they are 2 skinny they will be for the knacker

It would be unusual for a cow of 6 years old to have a parasite burden sufficient to cause a scour on it's own. You'd be worried with a cow like that that something else is hitting her immune system and suppressing it.

Could also have been a scour from acidosis if getting alot of meal or very high quality grass? Keeping her in with the calves on hay then would have dried it up. Lots of things it could have been depending on what else is going on.

Had vet here last week said to only do the younger cows. older lot should have built up immunity. Also to build up immunity you need introduction of the worms to the immune system. He was of the opinion that you can over do it with worm dosing.

I'm just after getting a bottle of a worm pour on with zero withdrawal, as the bulk tank test for worms was quite high. So should I just give it to cows 3rd lactation and under?

id say give it to all. thought it was younger stock too but vet told me dose all a few years ago, so got a bolus had zero withdrawal at time , worked well, vet blame overuse of certain injection i had been using covering all administered to young cattle as herd had no immunity to worms- his opiniion so dosed cows once year for 2 years and it worked,cleared dung like water anyway in 3 weeks and butterfat and protein improved ,could have been grass too but he claimed its effects all including fertility similar to lack of copper,

There's going to be serious errors made here if you start applying one rule to everything. Nature doesn't work that way.

A beef cow and a milking cow are two very different animals.

A beef cow is the best to apply the rule of thumb to but you want to watch out for the exceptions. The young cows under pressure, the old cows struggling a bit and the cow that is/was sick.

A milking cow is a high performance beast and as close to a beef cow as a donkey is to a racing horse. She's always under pressure to perform. When Eprinex first came out MSD produced evidence to support it's economic use in milking cows. I've no reason to dispute what they claimed: Extra appetite, extra milk, better fertility.

I'm still talking about stomach worms. Hoose is a different animal altogether. Strikes out of no where and destroys lungs better than a conventional pneumonia. Ignore that one and if you're unlucky you'll lose animals never mind milk.

The best approach is to talk to your vet as every person will have/need a different solution.
