... 2-fold for 72 h post-feeding, reflecting ‘specific dynamic action’, whereas ammonia and urea-N excretion rates were elevated about 5-fold. Arterial blood exhibited a modest ‘alkaline tide’ for about 48 h, but there was negligible excretion of metabolic base to the external seawater. P a CO 2 and P...

...Marshall D. McCue; R. Marena Guzman; Celeste A. Passement ABSTRACT Pythons digesting rodent meals exhibit up to 10-fold increases in their resting metabolic rate (RMR); this increase in RMR is termed specific dynamic action (SDA). Studies have shown that SDA is partially fueled by oxidizing dietary...

Over these 10 days, the cumulative energy expended on digestion and assimilation (specific dynamic action, SDA) was significantly ( P <0.035) greater for pythons (376±6 kJ kg –1 ) than for water snakes (323±21 kJ kg –1 ). In contrast, the SDA coefficient (SDA...
