Trichomonas

[inyati13]

I am getting 4 heifers ready for breeding. I was going to give them Bovi-Shield Gold 5 FP V5L. Then follow up with TrichGuard V5L to give them the second round of V5L as is recommended (Pfizer recommends Spirovac as the followup in 2 to 4 weeks after the Bovi-Shield so I would be using the TrichGuard in its place). That would provide protection from Trichomonas which is not in Spirovac. Does anyone have any experience with the Trichomonas vaccines that they could provide me? Thanks.

we dont have any trich problems around here yet but hardjo is here and im told is the lepto around here we have most of. i would add the HB into your bovi gold you can get it with the HB for about another dollar a dose. then come back with spirovac vl5 if you want to and i know this is not an answer on trichguard but just saying if i was vaccinating for one or the other which it would be. and do it 30 days before breeding date.

bse, that is good info. Since bulls are the prime pathway for Trich, do you know who provides a test for that? That way if you knew your bull was clean, it is unlikely it would be in your herd. On the otherhand, looks like you could bring an infected cow in. Infect your bull. Then the bull you thought was clean would infect your herd.

a vet would have to do the trich test id think. your are right on the bull being the carrier if you only bring in virgin heifers and the bull is clean no problems but a cow could possibly bring it in. if you havent had any problems with cows getting bred id think all is well with trich, and i was glad to see your bull was free of those defects.

Virgin heifers and virgin bulls are not problems. It's bulls that have serviced cows or possibly a cow that was serviced by a a trich infected bull. Check with your vet. In MO since last year any bull that has been used has to be tested fro trich before it can be sold except for slaughter. In MO the state lab does the test and it only costs a couple of bucks.

I am not having any trouble but with the new bull I probably would not see problems until the next time they are up for breeding if he is infected. He was never on cows before he came to me. He was pastured with a group of bulls his age. There have been several articles lately on Trichomonas and they have stated it is most common in the SE. KY is right on the line that normally is condidered SE. You and dun were helpful. Thanks.

It used to be considered a western problem. Startyed shouwing up more in the eastern areas after so many of the drought cows from the west were brought in a couple of years ago. Some states won;t let any bulls in unless they have a negative trich test

Hey, thanks again dun. Trich looks like a coming problem.

Hey, thanks again dun. Trich looks like a coming problem.

Only if you use bulls that aren;t tested or cows that abort.

 

[Red Bull Breeder]

You better just get the whole herd tested just to be sure.

BTW, The TrichGuard does have HB in it. I am not sure that the breeder included HB in their initial work-up, but the TrichGuard looks to me like it covers everything Spirovac VL5 does.

There is a full page on Trich in the undercover of Valley Vet Supply. It has also been featured in KCA, KY Cattle Asso. The Trichomonas is a protozoan. That in my mind would make it hard to vaccinate against. In fact, vaccines don't work well for some bacteria. But you have to be an immunologist to know the full scope of that subject. I would like to know what Lucky_P thinks of vaccinating for Trich or any other protozoan. For example, if their was an effective vaccine for Trich why wouldn't there be for Entamoeba histalytica, amoebic dysentery. Everyone going to africa or south america would get the shot. I got it once in Zimbabwe.

Just looked. They have developed a vaccine for E. histalytica. Don't have time this morning to google anymore on it. So much for that, still like to hear why Lucky_P has to say. Not sure how much immunology he has dug into but I know he is a vet pathologist so he has been exposed.

dun, same pathway with anaplasmosis. The vet said he never saw a case here until the cattle from the drought areas started coming in.

Got a guy flying in next week from Northern Arkansas to do just that. He said that is all he does!

Good then he might tell you that a long bred cow will not have Trich. Even a 2nd period cow likely would not have trich. Virgin bull will not have trich. Glad to see your getting some one with some smarts to help you out.

That's why I mentioned cows that haven;t aborted as being safe.

 

[Red Bull Breeder]

yep i saw that Dun. Thought the OP might just be amused by it is all.

That rules you out. First, you suggest that I have my whole herd tested. I thought you said that in humor, thus, my response which was sarcastic. If your suggestion to have my whole herd tested was sincere then I have two comments; First, I would apologize for misinterpreting your intentions; My second comment would be that your suggestion, however well intended, doesn't make sense in light of your second message. Your second message stated that none of my long bred cows would have Trich. Then why would you have made the recommendation to have my whole herd tested when almost every cow I have right now is long term bred. I ignore most of what you have to say and as far as I am concerned you can ignore me and we will get along just fine. You showed me what you have to offer on my thread about my bull.

 

[Red Bull Breeder]

I found it amusing.

Then, both of us are having too much fun.

As stated, virgin bulls are not a problem - and there's even some evidence that yearling bulls that become infected *may* be able to clear the infection - but older, mature bulls, with well-developed crypts in their preputial epithelium, must be considered infected for life, once they're exposed.
If you maintain a closed herd and only purchase virgin bulls - or bulls that have been tested and shown to be negative - you should be OK.

Most cows that are infected will conceive, but abort early in the pregnancy. You usually don't see an abortus or membranes - just a cow that you thought should have been 3 months or so along, coming back into heat. Most cows will eventually develop local immunity and will conceive and carry to term.

bse, hate to tell you, but I've seen positive Trich tests on bulls out of southern middle TN as far back as at least 4-5 years ago.
Anaplasmosis - I never saw or suspected a case when I was in practice in Giles Co., TN back in the '80s, but had a classmate 70 miles south of me, in AL who saw it all the time. Have been here in southern west-central KY for nearly 20 years now, and have seen cases of anaplasmosis coming through the lab every year - some years worse than others.
