We started with Ivomectin and was using it once per year in the fall after it cools down.
We switched to injectable for new arrivals only, the rest are managed with pasture management.
As an aside, after we quit with regular use, our Dung Beetle population exploded and piles are quickly taken down.

Most important thing I can say: Alternate between dewormers. Resistance can occur with parasites, just like bacteria.
Don't use the cheapest one you can find thinking every dewormer is the same. Some generics are not effective and a waste of money.
Treating cattle one time does not kill all parasites they harbor, and it does not prevent re-infection.
The moisture, temperatures and tillage/lack of tillage (direct sunlight exposure on parasites eggs/larva) of your environment may alter deworming protocols in your area. As always, cost vs benefit.
In our area, studies support that deworming twice yearly is economically advantageous.
We alternate between Ivermectin and Dectomax.

Pour-ons dewormers are losing effectiveness. The best way to deworm
is over the gums(oral)...Safeguard or Valbazon (watch Valbazon because there is only a window of time
to use it~it's written on the label.) Injectible
dewormers are second in effectiveness, way more effective than pour-ons.
Pour-ons work well for lice and grubs, but they aren't an effective
de-wormer. Only 50% effective...BEEF Magazine, Drover's, etc have
all ran articles on this very subject. I've been telling you all this for
a few years now.
If you deworm early and you get some warm weather and some moisture
there it is highly likely that your cows will get reinfected. Best to wait
til late November...FWIW...
I did find this:
RESISTANCE IN THE U.S CATTLE HERD
To date, research of anthelmintic resistance around the world has focused primarily
on sheep and goats. Researchers in the United States have documented resistance in
horses as well. But only in the past couple of years have reports of resistance in U.S.
cattle herds been documented and presented to the veterinary community.
One of the first cases documented in the United States was described by Dr. Lou
Gasbarre, research leader with USDA's Agricultural Research Service, and Larry
Smith, DVM, Smith Research and Development, Inc., Lodi, Wis., who studied a
Wisconsin background operation where the owner noticed an apparent decrease in the
effectiveness of his strategic anthelmintic program. Upon evaluating parasite loads, it
was noted that treatment with ivermectin injectable, moxidectin pour-on, doramectin
injectable, eprinomectin pour-on or albendazole oral did not result in parasite burden
reductions of at least 80 percent.
"In the past two to three years, it has become evident that the modern anthelmintics
upon which the American cattle industry relies have begun to show diminished efficacy,"
said Dr. Don Bliss, parasitologist at the MidAmerica Agricultural Research Center,
Madison, Wis., who has monitored thousands of fecal samples from cattle throughout
the United States over the past 20 years. Bliss said he sees examples of anthelmintic
resistance on a daily basis.
