Pinkeye after being worked

Postby ClinchValley » Fri Jul 13, 2018 7:11 am

Got all cows and calves worked in May. Cows were given a pinkeye shot, amongst other things.

Noticed yesterday i've at least two cows that have pinkeye coming on. Might be more, going to check and treat today.

Was talking to my neighbor. He said the pinkeye vaccine medicine can be cloudy or clear. He said the clear works where the cloudy does not. same stuff. One bottle can be clear, on can be cloudy.

Does anything about clear/cloudy bottles make sense? anyone ever heard that?

There are two species of bacteria that cause most pinkeye. Both of the genus Moraxella. My vet is Dr. Darin Stanfield. He says that only custom -autogenous vaccine - vaccines are effective. I use the vaccine he has custom made for the strains of Moraxella in this region. I have not had a single case since using it.

Adding to this, dont quote the number but there is like 140 possible strains that could cause pinkeye. 2 years ago I used a vaccine that covered 104 strains. Had the most pinkeye I had seen in years. I think good pasture management and using the custom made can help. This year I didn't vaccinate for pinkeye and have 1 case where the grass heads got big.

I have always mowed pastures on a regular basis. Some areas 3 times a season. I still had pinkeye until I used the autogenous vaccine. Nevertheless, I still wonder if it really does anything or whether these outbreaks of pinkeye in my herd are a cycle. So much of what I see is anecdotal evidence and dangerous to draw hard conclusions on that evidence.

No evidence at all but I feel they develop some immunity as a herd after being exposed. After a year of having it I have nothing usually the next year. Bringing in New animals may change that and I'm always bringing in New.

100 % agree. I sometimes think it is a natural immunity function. Pinkeye ran through my herd about 5 years ago. That is when Dr Stanfield recommended the autogenous vaccine. I used it and have had maybe 2 cases in the last 4 years. I often wonder if they simply developed natural immunity to the strains I had here and I am giving the vaccine undeserved credit!!!!!

Noticed one of my girls had a cloudy, watery eye about 6 weeks ago. Could not get her caught but after about a week it started clearing up, never ulcerated. Couple days later I went down to the barn & she was literally standing next to the chute but I didn't run her through because it was almost completely gone, just a tiny white dot. Can't see anything now, it's totally clear. I vaccinate every year so was it the vaccine that essentially healed it? Or natural immunity? A small abrasion or seed that worked its way out? Things that make you go hmmmmmm . . . .

I wonder. We had a really bad outbreak in the replacement heifers, also about 5 years ago. Did absolutely nothing to prevent future outbreaks and to this point have not had another case. Which isn't to say I won't have another.

We have not had it for years; this year 6 cases now, of which 3 were calves still on the side of cows! It comes on FAST, and is resistant to treatment. I had the vet out before we left to the National show, 5 treated at that time but 4 were still symptomatic several days later. Vet injected 3 of the 4 in the eye to help clear it up. My new case popped up three days ago, we treated it as soon as we saw it. Her eye is still white, and irritated. I might have to call the vet out again, this strain I am dealing with is persistent. We have almost NO flies (ask Ron, he was here for 9 days watching our place), but there is some stem in the fields we are grazing (it was brush hogged, but some regrowth sent up seeds). No rain for 30 plus days (we are in d-2, severe drought category according to the US Drought Monitor), we are VERY dry and crunchy, so everything is sharp and painful when you step on it! I imagine the cows don't care for it either when they put there heads in it grazing!

Lots of factors, but stess is a really big one.
So heifers are more likly to break than cows, poor pasture is more likly to experience a break than good grass.
We see it here most often with the pasture hos who set stock some young cattle on rough rented ground till it is eaten down to the roots.

Interesting. Thanks to all for the info so far.

I used pinkeye shield from our local CO-OP. New to all this, didn't know there were so many strains, and definitely wasn't aware there are custom tailored vaccines for this area. Now I know.

I've mowed once already. About to have to mow again. I'm thinking my problem area is having only so many water locations. And limited shaded areas. Pasture has been good so far, knock on wood. Maybe one or two seed heads per square foot in places. In places, none. Maybe 10 percent of pasture is inaccessible to a tractor, and is stemmy. But cattle see that ground maybe 4 days our of a month.

What do you all do for flies? This far, i've sprayed them from time to time. Due to how this farm is set up, a rub wouldn't work but half the month at best. Have considered putting the mop things on my homemade (plastic barrel) mineral feeders. Anyone use the mops?

Thought about it, i could come up with a mobile rub…maybe.

Right now I am pouring about every 18 days with UltraBoss. Real effective but it would be a pain if I had cows that would not stand to be poured in the field. In that case, I would spray with a Synergized Permethrin in a small pump spray.

You ask "was it the vaccine that essentially healed it?" Probably not. Look at some of those old tests where they test 100 or so calves that have pinkeye using different vaccines. They always have a control group where nothing is used. It always surprised me how many of the untreated just got over it. In some tests I have read about, the percentage of untreated "heal ups" was not much difference than the treated cases.

I think one of the best things to do this time of year is to just get them out of the sun for a while. Lock them in under a cover.
To me that is why patches seem to work well They keep the eye shaded.

I have seen some of those studies where the vaccinated group does no better than the control group. Some bacteria are difficult to vaccinate for, i.e., Moraxella. Virus vaccines as a group provide better immunity.

Another example - there are studies on the practice of giving GnRH at the time of AI. Some studies show the conception was just as good in the control group as it was in the group getting GnRH.

Sounds like a chance to see some immunity to Ultraboss and similar products pretty quickly at that pace. Are you using the 200 flies per cow threshold to treat?
