Hi, Hope someone can help my Dad. He has had a couple calves go down and recover and a couple calves die in the last couple years. They appear to be fine and then they just go down. Seem to be paralazed in the hind end. They are all about 6 months old. Vet has been called on everyone and they are saying it is coccidiosis. Blood and fecal samples have been done on other calves. This recent calf vet was called as soon as she was found and that was Thanksgiving week-end. She is still not getting up. Eating and drinking great. Gaining weight.. Dad is raising and lowering her frequently and massaging her limbs. Any ideas what this could be.
