[QUOTE="som farmer, post: 9273295, member: 86168"] 6 weeks was the recommended age to wean them, that used to come from the likes of ADAS, powder people the trade, BOCM etc. did some work with denkavit back in the early 20's, some of that was weaning earlier, and increasing the amount of powder used, with less water. l think it was BOCM that recommended you didn't wash out your milk buckets, from start to finish, wouldn't dream of doing that now. The idea was that the residue grew the correct bugs etc, actually tried that, with a batch not doing, and to be fair, it worked. l am one for clean buckets, so only tried the one batch, but it really isn't much different to adding natural yogurt to the mix, just to messy. we do things differently now, like us, a lot of people wean 8 ish weeks. Stuck with only feeding 2 litres/feed, or less if a small calf. Certain reducing liquid volume in milk, gets them eating conc quicker, and more of it. the 6 week weaning, came with the proviso, had to be eating 2 kg of conc, so really, if they are eating 2kg, they should be ok to wean. And to be fair, OM always weaned at 42 days, and the calves always did ok. But then hfrs calved at 3yrs, not 2. We probably wean more by size, than age, some might be 10wks +. Perhaps that's more to do with not buying much powder ! what works for us, might not work for others, we usually top the mkt with our stirks, so must be doing something right. vaccination, we did our dry cows with rota vac, and an excellent response from that, this last winter was the 2nd we vaccinated the calves, at 7/10 days old, with bovolto, respiratory one, vet tech calls in x1 a week, and did them. This year, we didn't do the first 15 or so, not deliberately, just 'drifted', but it did give us the opportunity to compare. And an unhealthy winter, we didn't lose any, but had more trouble with that pen, than the rest, calves were a bit smaller, perhaps. vaccination is firmly on the to do list. Farm we are taking from, is doing it (y) (y) [/QUOTE]
