rego the dry cow period of nutrition i just as if not more important than the lactating feeding. Ca is one the primary culprit in milk fever but it is not lack of calcium but rather feeding too much calcium during the dry period in both the grain ration and the grazing and/or hay fed. One reason a well formulated and balanced dry cow feeding program will eliminate a huge majority of milk fever cases as well as retained placentas.regolith":3djtolry said:It's not uncommon at any stage of lactation in NZ dairy herds... in fact, I think a lot of farmers don't recognise it when it happens at an unexpected time. Being on heat is a risk factor for MF, so is supplementation with certain minerals (zinc).
Just agreeing with TB: it's probably not the case here but it's the first thing to cover with a down cow for any reason... doesn't hurt, as long as Mg not given too fast into the vein.
