[QUOTE="Dempster, post: 1776481, member: 32761"] So before we all jump ship from Inforce to Nasalgen, a couple questions. Does anyone have issues with bacterial pneumonia in pre-branding age calves? Mannheimia in these calves certainly exists, but it isn't common. I see it by far most commonly in calves out of first calf heifers, but not all that much in the cow herd. If it's the cats meow, why haven't we all already been doing it? Merck has had the Once PMH IN Mannheimia/Pasteurella product for a number of years now, add it to either inforce or straight nasalgen, and you basically have Nasalgen PMH. That option has been around for quite a while. Does it work? I know merck has their studies show duration of immunity, but can you give pasterurella to a newborn and really expect any kind of decent immunity. When a calf hits the ground, everything its immune systems experiences is new. If you squirt a viral/PMH vaccine up its nose, it is trying to respond to that now on top of everything else, how much can an 8 hour old immune system really do all at once? I don't know the answer, but I am skeptical. I'll offer up my experience with these products. If you have a herd that doesnt have issues with pneumonia in the first 6 weeks of life, these products will work great in your herd. I don't care which one you use, you will probably still not have issues with pneumonia. I've worked with a number of herds that have pneumonia issues in these calves, I've tried all of these products in newborn calves in these herds and have yet to find one that seems to consistently improve the problem. My opinion on these products is if you have disease in these young calves and are looking for vaccine options, the vaccine needs to go into the cow, doesn't matter if you are dealing with scours, purple gut, or pneumonia, the cow has an immune system that can handle these products and make antibody. PMH vaccines are all expensive, if we aren't having issues with the disease, maybe we should wait to make that vaccine investment until branding time when the calf is likely to respond a little better to it. In baby calves that do have these issues, I think there are better interventions. [/QUOTE]
