Got dung samples of weanlings tested n November as doubted may have rumen fluke as scoury. Doubts confirmed and advised to treat with levacide diamond. All weanlings treated shortly after housing no problems alls well. Some of cows scoury also so decided to treat same last Thursday after being housed 7 weeks. Dosed cows guessin weights. All fine Friday, Saturday two cows unable to get up like as if no power n back legs. Cows lively n head eating and drinking. One of them up tis morning and a different cow unable to get up on back legs today. So have two cows un able to get up again tis eve. Is it a case of being over dosed? Will they an unborn calves be ok due to calve Feb / march? Worried. Tia.
