Abstract

Literature data on apparent ileal digestibility of crude protein (CP) and amino acids in pigs from 79 references (203 observations) including 13 different common feedstuffs, and other data on basal endogenous ileal loss of CP and amino acids from 32 references (36 observations) were analysed statistically. The analyses revealed that the cannulation method as well as the method for determining endogenous ileal losses of CP and amino acids affected the results. After correction for these effects a new set of tabulated values for apparent and standardized ileal digestibility of crude protein and essential amino acids was generated. The results were in most cases in good agreement with three recently published tables for standardized ileal digestibility of amino acids in feedstuffs. Therefore, it was concluded that the data obtained in the present work, together with those given in the recently published tables, would be a suitable basis for a general table for standardized ileal digestibility of CP and amino acids in common feedstuffs for pigs.
