I talked to a friend this morning that has taken in around 125 head of 5 wts and currently he has lost 20+ to mycoplasma. He had the vet out and did tests. I am not very educated on this but I've been told there isn't much you can do to vaccinate for it? Any and all help and suggestions would be helpful. Thanks
If he's already lost that many, he needs to mass treat everything else with Draxxin. I hope he's already done so. A lot of these calves with Myco that you think you've got straightened out will end up as repulls two or three weeks later. The Draxxin will take care of most of that.
With what I've learned about Myco over the last couple of years, you can't fool around. Some of the early symptoms are so benign that you just can't waste any time. You've really got to be on top of things and spend a LOT of time with those cattle. You'll be way behind and it'll be too late if you don't get to know them and let them get to know you so that they're comfortable telling you when they don't feel good. Things like a calf having one ear down, or just having the neck stretched out a little more than normal, or walking a little stiff are things that you need to be watching for and at least pull to temp. Get to know those cattle and let them be comfortable with you, so they don't see you as a threat and fake feeling good when you're around.
If I can only treat once, my first choice for treatment of an active case would be 3ml/cwt of Baytril, plus 1.1ml/cwt of Draxxin, plus 2ml/cwt Banamine, plus a Probios bolus. The Baytril will start working faster than the Draxxin, but the Draxxin will give you longer protection.
If you want to try to save a little money and have the time to keep messing with them, I've had some success with LA300 at 3ml/cwt given every other day for three treatments. I give the first day in the muscle and the next two SQ. That has worked on about 60% of the ones that I've tried it on, but I'm not sure that a person isn't better off to go ahead and spend the extra money and get them back to work quicker.
If the calf is already crippled or has a severe head-tilt, I wouldn't spend much on him. Probably the best thing to do is to go ahead and shoot those, but I really have a hard time doing that without trying something. In the case of those, I'd just give a big dose of LA300 and hope for the best. If you see some improvement the next day, you might hit them again, but most of the ones that I've had like that usually end up in the dead pile anyway.
I've not seen anything about the vaccine that makes me think it would be worth it. Especially on calves that are shipped-in and that are most likely already exposed. I'd spend that money on a round of Draxxin instead.
