Laboratory testing in 10 "Walliser Schwarzhals"-goats included red and white blood cell count, electrolytes, liver enzymes, trace elements and urinalysis, protein determination and cell count of the cerebrospinal fluid (CSF) was also performed. Electrodiagnostic testing included electromyography (EMG) of the head and spinal muscles, motor nerve conduction velocity (MNCV) of the right and left peroneal nerve, brainstem auditory evoked potentials (BAEP) and electroencephalography (EEG). MNCV of the peroneal nerve was 72 +/- 9.24 m/s. Latency and amplitude of the BAEP for P1 was 2.15 +/- 0.08 ms respectively 2.23 +/- 0.7 microV and for P5 5.09 +/- 0.15 ms respectively 0.68 +/- 0.24 microV. P2 (3.2 +/- 0.14 ms/1.37 +/- 0.32 microV) and P3 (3.9 +/- 0.13 ms/0.84 +/- 0.14 microV) were equally distributed between P1 and P5. Whereas the results of EMG and BAEP were similar to those of other species, the electroencephalographic findings consisted of three different patterns depending on duration and depth of isofluran anesthesia. Pattern I had a rhythmic high amplitude (80 microV) and low frequency (1-2 Hz) pattern with aperiodic intervals of relative electric silence. Pattern II was characterized by increased duration of HALF (150 microV), associated with spindles of low amplitude (20-30 microV) and high frequency (10 Hz). Pattern III had generalized delta-activity of high amplitude (70-200 microV). All the results are discussed briefly.
