Protein digestion in pigs measured in vitro.
In vitro determination of protein digestibility by treating feedstuffs with pepsin-HCl respectively with pepsin and trypsin yields results that differ considerably from the ileal protein digestibility figures. Comparable results for N and lysine are received when the largest polypeptides in the solution obtained after peptic and tryptic treatment are precipitated with copper hydroxide.
