Time to think deworming the beef herd (with avomecterin products)

[Faster horses]

We have done extensive work on this several years ago, when Dr. Bliss, one of the world's foremost parasitologists did some
research in SE Montana. He set up a Wisconsin spinner at different ranches to check fecals for worms. He found cattle built an immunity to avermectin products. He was very brave at the time and talked about it in interviews which was published in magazines and newsletters. The people working for the company that made avomectrin products pushed back and not a lot came of it.
Now it seems universities are finding the same thing he did. We recommended SafeGuard (fenebenzole) in the mineral or drenching with SafeGuard oral drench. It's easy to do strategic deworming which cleans up your pastures, with mineral containing SafeGuard.

Time to Rethink Deworming the Beef Herd

The use of commercial livestock dewormers has paid off in terms of animal health and productivity, but it has also resulted in resistance

I found tapeworm egg sacs(?) or segments showing up in one of my cows early last fall. Had not seen that in cows before. The only information I found said the white wormer, Safe-Guard would address tapeworms. So not wanting to try wrestling with drenching the cow, I used the Safe-Guard feed pellets, the information recommended giving it for three days.
Information also indicated that the Safe-Guard has less impact on the Dung Beetle, which are present in the pasture my cows are in.

You are correct. SafeGuard is the only product that controls tape worms. We had several fecals run on our cows (veterinarian using the wrong implement to do a parasite analysis on cattle) and the results always showed tapeworms. The vet said that tapeworms did not do economic damage (hah!). After having 2 parasitologists do on-site ranch analysis of parasites (they set up at one ranch and we had neighboring ranchers bring their samples). Ours showed tapeworms and stomach worms, and...so we dewormed our cattle with SafeGuard. You could actually SEE the results. Our cattle kept better condition after deworming with SafeGuard.

At one point I was a hard person to convince cattle that ran in arid hills, had a worm load. We did our own test. We had young cows at home and older cows at another ranch. We dewormed the young cows at home--strategic deworming 6 weeks after turnout. That fall calves from those young cattle (2 and 3 year olds) out weighed the cows calves by 20 pounds. That made a believer out of me. We used mineral with SafeGuard in it.

Yes, deworming over 3 days is good. Dr. Bliss said that deworming over a longer period of time vs. one
big blast, gets rid of more worms. Young cattle carry a bigger worm load than older cattle. That has been proven true over and over with the fecals we have run.

Is the mineral/SafeGuard mix a pre-mix, or one you did for yourselves?

I actually invested in a computer run program to check for parasites in the horse. The microscope connected to the computer and put the image from the slide onto the computer screen. Made it easy to do egg counts. It would work for most any animal. When Windows 7 went away so did the program I had down loaded. Don't know if I could get it up and running on the new computer. But it was interesting to see the timing/fluctuation of the higher levels of egg counts. They were totally out of sequence compared to what the recommended worming charts showed. Even on a twice a year worming program the horse was showing really high egg counts in July.
