Abstract We quantified the specific dynamic activeness (SDA) resulting from the ingestion of diverse meal types in Burmese pythons (Python molurus) at 30°C. Each snake was fed a series of experimental meals consisting of amino acid mixtures, simple proteins, simple or circuitous carbohydrates, or lipids equally well as meals of whole fauna tissue (chicken breast, beef suet, and mouse). Rates of oxygen consumption were measured for approximately 4 d after feeding, and the increment higher up standard metabolic rate was determined and compared to energy content of the meals. While food type (protein, carbohydrate, and lipid) had a full general influence, SDA was highly dependent on repast composition (i.e., amino acid composition and sugar structure). For craven chest and elementary carbohydrates, the SDA coefficient was approximately one‐third the energetic content of the meal. Lard, suet, cellulose, and starch were not digested and did not produce measurable SDA. We conclude that the cost of de novo protein synthesis is an important component of SDA afterwards ingestion of protein meals because (1) simple proteins, such as gelatin and collagen, did not stimulate levels of SDA attained after consumption of complete protein, (two) incomplete mixtures of amino acids failed to elicit the SDA of a complete mixture, and (three) the inhibition of de novo protein synthesis with the drug cycloheximide caused a more than than 70% subtract in SDA. Breadbasket amplification and mechanical digestion of intact prey did not crusade measurable SDA.
