Wouldn't cydectin (moxidectin) be a better choice than ivermectin for deer? Longer effect, less restriction on consumption before slaughter.

Some encouraging results out of connecticut

Recipe they used is bottom of page 3 and 4 (not that I would ever need that), pictures on page 7 tell the story better than the text does imo.

We are using Cydectin on our cattle with Cotran for wounds.

Totally different landscape. 60s and 70s were family ranches where the ranchers all pretty much did due diligence but there was no wild hog overgrowth, no hobby ranchers who will not spend the time being educated or follow procedures, and entirely different deer hunting system without feeders, baiting, population sizes, etc.

I'm one of the multi-generational ranchers with 6 section, 4 section pastures in multiple states. The hobby ranchers and feeder deer hunters will cause massive issues that we didn't see in the previous outbreak generations ago. The me, me, me, I'm small potatoes so no issues on my end will cause this one to be bad. Real bad. Bookmark this - the masks and toilet paper hoarding will be nothing if this things goes wild in the US cattle population - sadly, I think it will. Lord, oh, lord, may I be wrong.

Watch just one episode of Lone Star Law and see the average intelligence of the deer bait/feeder station population. Now, there are some smart ones but sadly that's the definitive minority. And I'll call out L&E for wanting to medicate their feed. Total PR ploy. No way to control or monitor consumption and distribution.

I am not going to pretend like I know how this is going to play out, especially given I wasn't alive for the last outbreak. However, I do know of the stories the ranchers told about how bad it was in their sheep and cows and how their lands were almost void of deer too - especially where I have hunted for the last 25 years.

What I don't understand is how you're already blaming hunters for something that has nothing to do with them right now… not trying to be a triggered little snowflake, I'm just genuinely confused on the lashing out.

Perhaps all of these hunters and ranchers with the billions of dollars they spend every year on deer hunting/ranching, are going to bring more attention and potentially more innovation to help slow or stop the spread?

It's also not really an fair comparison given the deer population in the state is anywhere from 5-10x what it was in the 70s, so it will inherently be worse regardless of feeder hunters or whatever term you used…

We all want to stop it and I don't want this thing impacting the cows, sheep, deer, or anything (well, maybe not the aoudad).

Knowing this came up from central America to Mexico to Texas, we will have to solve the Texas population AND the Mexico / Central America population. Or it will continue to show up in Texas.
Will be an interesting summer and fall. We need an early freeze this fall.

Every domestic and wild animal can potentially get and transport. The deer you are harping on are just a small part of the overall population. Deer feeders don't have anything to do with it. Most wild animals don't eat deer corn.

It would be great to find a way to save the deer herds by feeding but that's a long shot and it won't solve all the other animals getting it. L&E is trying to help so don't blame them. Smart people are working on this so maybe they will find a magic bullet.

Go to a Tscra meeting and educate yourself on this subject.

We can weep for the land ownership changes that are in play now compared to the 60s and 70s. Maybe it's a shame that the big properties with horseback ranch hands who could treat livestock with screwworms are a thing of the past. Should we point fingers at the heirs of those properties who sold their divided shares to folks who purchased the smaller properties for recreational hunting?

Seems unproductive to me.

Irregardless, the situation is what it is and it has to be dealt with accordingly with all landowners being active and responsive. The good news is that NWS has been eliminated before and it will be done again, even more prescriptively than it was 60 years ago.

so in reading here a younger guy asking question is belittled by an older guy that was around for last outbreak! Seems like a great educational method! I myself have questions, but spare me the belittling, i'll just do my own research. So many times this board is a great educational tool.

L&E isn't trying to help. Sorry, not sorry. They are opportunists. No way to medicate a wild animal feed that's effective, it actually could do more harm than good.. Yea, they fill your feeders fast and on time but they are not the saviors. They saw a monetary option and pursued it. It wasn't a good will gesture.

Then why are they trying to medicate wild animal feed?

As for education on this, we are a front line control outfit and are working with some "smart people" on this.

Yeah I'm not so sure about that and don't like to think never going to happen. Maybe ivomec treated corn isn't the answer but what about fluralaner or something else in the pipeline? I don't have a dog in this fight relating to the feed business, but realize we need to try something or do nothing occasionally.

Interesting that Fluralaner is the approved topical pour on to treat and prevent the NWS in cattle - Exzolt, And is the ingredient in the 12 week dog flea/ tick prevention Bravecto, And is the ingredient in the 365 day flea/ tick prevention shot Bravecto Quantam.

Will the Dog flea/ tick long term prevention meds also prevent NWS? Will it work on Deer? Cattle?

ETA. Treat a sample study in the quarantine zone with the injectable 365 day dog med, put trackers on the treated, and find out. Goats, deer, cattle, etc.

I recently read that biologist are predicting 80-90% fawn mortality. I'm just not buying it this year. The flies are here and showing in small numbers but I just don't think they will be that big of an impact this year. Hope I'm right.

I hope you're right. Our fawns drop in the next two weeks based on history. We had one calf drop in last two or three days and he is clear as of yesterday.

Some bad information there sir. I have been in the wildlife field since getting out of TAMU in WFS in the 70's. I have game managed ranches and my own and we have used medicated feeds for worming deer and exotics since the 1970's with great results. Used pellet medicated feed every spring on many ranches as a dewormer with very great results.
Right now, in Missouri, there is some conversation that they are testing treating pellets with Ivermectin and having some encouraging results with keeping ticks off deer and elk.
Deer feeders have been used in Texas since the late 60's and early 70's. 50 Gal barrel feeders were very common in those years. They are not a new thing. People have been baiting deer in Texas since the 1950's.
The late Gene Bode of Bode Feeds in Harper Texas was on the forefront of developing medicated feeds for cervidae and exotic hoofstock in the late 1960's. It was used by many ranches in the hill country with very good results.
L&E sell feed for sure but they also have some very knowledgeable biologist and animal nutritionist on their staff (some Aggies) that have great knowledge in this field.
Deer feeders and deer hunters don't have a thing to do with NWS.

Some isolated areas my see some high fawn mortality.
If we get a good handle on this thing, and minimize the longevity of it to a year or less......the worst case scenario of fawn mortality will effect just one generation of fawns. If this thing is indeed wiped out quickly (sure hope it is)....and even if we do lose some fawns this year, mother nature usually adjusts to that change quickly and the next year we could have a very high fawn success year.

Yea? I'll add that range conditions are far better in much of the state due to more rainfall and cooler temps. I think otherwise this year may have a much lower mortality rate. I do agree that higher density on some of these ranches could negate the potential for better range conditions.
Going to be some bumper coyote crops.

You and I been doing this long enough to know that range conditions in some areas may "appear" to be good right now due to the recent rains. However, many types and species growing good right now are legumes and forbes that have a very low tolerance of hot and drier weather and will quickly not sustain once the rains stop....they will be the first to die when it dries up a little.
This can have a very negative effect on fawn survivability long term..... as when conditions are good, and as all the mama deer have plenty of food the doe/fawn ratio number spikes. But then those wet weather legumes and forbes peter out when it gets a little hot and dry and you have a large fawn mortality because of it.
To have a long term "repair" of the rangeland, many areas of Texas need multiple good years of rainfall like what is going on right now in some areas. That way the base dry weather legumes and forbes will have a chance to reestablish in the range.
You and I both know that it going to take multiple back to back years to bring the range back in many areas long term. One good year is not going to fix the 7 bad years before it.

Would be curious to read that prediction and also see who's making it.

Not to stir the pot, really just to get the biologist's take on the matter.

We have had 6 detections this week which may seem like small numbers, but we don't have detections where we are seeing them without A LOT more flies out there. I think we are way underestimating what is actually going on out there.

I feel like breeder/high fence operations are going to be just fine since they can keep a better eye on things.

Breeder operations will be able to monitor easily. The question is will they bother to report anything with all the CWD stuff going on. But if there's a spot where treated feed could work, a breeder one is one of them.

I agree. The fact that so many detections popped up so quickly suggests this is just the tip of the iceberg.

Oddly enough, no wild NWS flies have been detected in any of the thousands of fly traps deployed along the border.

The choice to not report is a concern, in my opinion. People don't trust government. So many rumors out there the gov't will come on your place and implement crippling measures. So people won't report.

Aside from the fact it is the law to report, I think the most compelling reason is that the infected area will be concentrated with sterile flies. And flies are the proven way to eradicate.

I was talking to a buddy of mine this morning who runs a cattle operation. He was saying he was listening to Sid Miller in the radio and he even said if his cows had it he wouldn't report it because of the headache that's about to come from it.

So the major heachaches i guess are quarantined. Vet inspects the livestock before moved out of that area. Rancher I imagine has to pay for this vet service or is this by governmnet?

Rancher if they choose will have monitor the livestock more frequently.

Are those the cons? I am wanting to understand this from the perpective of someone whose livelihood is the livestock or even others to further my knowledge from real world instances not the internet search button.

What are the pros of reporting?

Thisguy1
How long do you want to ignore this user?
I'm not sure the specifics of it. My buddy said he thinks it'll get pretty bad, but he isn't worried about his cattle because they're checked regularly and it's easy to treat. He thinks it'll get pretty bad for wildlife and just the amount of cattle around here that don't get checked regularly.

He's more worried about some type of mealybug that's posing a threat to pastures. Called it the chinch bug of pasture grass and there's not an approved treatment for it.
