Two to three month old kids (goat) went down on back end. Animals alert and still eat. Had three other kids do the same thing. Most get weak in hindquarters first but can get weak in front first.

Microscopically- Pulmonary edema and congestion, brevity of Purkinje cells in the cerebellum and axonal degeneration in the peripheral nerves (namely sciatic nerve).

Chemical analysis- Liver copper was 1 ppm (adequate=25-150 ppm).
