Nutritional and Physiological Functions of Amino Acids in Pigs

Abstract

The measurement of the ileal digestibility of amino acids is a convenient method for measuring bioavailability of amino acids in feedstuffs for pigs (Yin 2008). Because of the presence and metabolic activity of microbes, as well as the absence of amino acid absorption by the large intestine (except in the neonatal period), amino acid digestibility determined at the distal ileum is more accurate than fecal digestibility (Zebrowska 1973; Yin and McCracken 1996). That is why many scientists developed numerous surgical techniques to collect ileal digesta, including the slaughter and cannulation techniques. These latter cannulation techniques include:
