Total serum protein (TSP) levels were recorded for the adult cohort in a population of southern Florida raccoons (Procyon lotor marinus) for a period of 1 year. TSP levels were found to fluctuate seasonally, with autumn levels being the highest and spring and summer levels the lowest. Values for males tended to be higher than those for females. There may be a correlation between mean TSP levels and mean body weight. In 10 male raccoons recaptured during the study period, the same pattern of fluctuation in TSP levels was observed.
