The only animal that should ever see LR is something that's gonna have its head cut off, like stockers - which should not run with, or on same ground with the cow-calf herd.
Use in a cow-calf operation is a disaster in the offing, with regard to rapidly selecting for resistant nematode parasites. It's there every second of every day for months. Is the dose you gave that 200#calf still appropriate and effective 5 months later when he's 300-500# heavier? IDK, but I've got doubts...but regardless, it's still there, selecting for resistant parasites.
LR-treated heifers should not be brought back into the breeding herd...they'll be bringing resistant worms with them.
Resistance to the ML and benzimidazole dewormers appears to be 'forever' once you've selected for it in your herd/on your premises.
And, using LR - or any pour-on macrocyclic lactone(ivermectin class) for 'fly control' is sheer lunacy.
SBMF 2015 said:I did an on farm two year trial. We have five pastures that are with in a township of each other. So we decided to run our own trial on Long Range, injectable Cydecton, and injectable Dectomax.
The first year our drug rep gave us enough LR for 40 pairs. So we treated 2 pastures with LR, 2 with Inj Cydecton, and 1 with Inj Dectomax.
Our nutritionist ran fecal tests and we were pleasantly surprised at the results for the LR. Cydecton was ok and Dectomax in satisfactory.
All the cow winter at home, co-mingled, and are given an oral wormer (Safeguard, Synanthic) at preg check time.
Year 2- We had to buy the LR this time, we treated 1 pasture for a 2nd year and one for a first year. The other 3 were given Cydecton.
The cattle on the pasture that had been given LR for the second year was the worst parasite load. It only took a year to build resistance.
The one thing I like about LR is that cattle treated with it will have no flies. That's a nice side effect.
I know some producers that give LR just to their suckling calves, and claim it reduces the flies in a pasture. It doesn't cost a lot of you are only treating the calves.
Most vet clinics can do them. If not, they have access to a diagnostic lab they could send it to.Brute 23 said:SBMF 2015 said:I did an on farm two year trial.

How hard is it to do a fecal test or is there some where you can send it off?
What I am getting at is I wonder if worming spring and fall is necessary ever year. I would rather test it and see when it is necessary.

What would a microscope good enough to do it myself cost?
I can count sperm on a slide so surely I can see a worm egg or larva.
Any microscope good enough to see sperm will work for parasites. The hardest part is learning to identify the parasites you see.
