[QUOTE="regolith, post: 1091312, member: 9267"] Do you get a lot of ryegrass staggers/FE where you are? The rust has been showing through on the pasture this last three weeks, getting pretty bad. What surprises me is that it's appeared at its usual time of year, no earlier. I would have expected the warmer conditions to have created an earlier boost in fungal impacts, but it doesn't seem to have happened. [except in my garden - pulled some blighted tomatoes up yesterday] I suspect the example given earlier of an un-noticed infection is the most likely trigger for the hoof growth. I wouldn't say laminitis never occurs in these conditions, but it's rare. Neurotoxins are always a possibility and I doubt you'll ever identify them. I see spring eczema every year which I believe are caused by neurotoxins (not sure what the official view is at this stage) but all these years and no one knows what causes it and there's still no treatment. Had the vet out to see a cow who'd dried up (it was pneumonia, no typical symptoms, she didn't look sick) and she told me the spring eczema had been occurring in waves this year, not continual. I could name three of those times - early to mid October, early December, late December/early Jan - because that's when I was seeing it in my herd. That late Dec/early Jan period I think my herd have taken a big hit to their immune function generally, not sure why and not sure if we're out of it yet. [/QUOTE]
