Oral and Poster Abstracts

Materials and Methods: Serum samples from recumbent cattle were
selected from samples submitted to a laboratory in Germany for
analysis. A questionnaire was completed in order to obtain data on the
duration of recumbency, time of sampling, breed, and treatment
outcome. Serum concentrations of Ca, Phosphorus, Mg, Na, K, total
bilirubin, urea, and total protein were measured, and serum activities of
AST, CK, and GLDH were determined. Analysis of variance was used
to compare serum values of cows that did not recover and were
sampled before (group NR1) and after (group NR2) their first treatment
for recumbency, and recovered cows that were sampled before (group
R1) and after (group R2) their first treatment, respectively. Nonnormally
distributed variables were log transformed before analysis
and P
