Growing pigs provided with ileocaecal re-entrant cannulae were fed three rations containing plant protein sources and two N-free rations. The crude protein and amino acid flow in the digestive tract as well as the apparent and true digestibility of the crude protein and the amino acids for the individual sections of the intestines are explained. It shows that relating the calculation of metabolic faecal amino acids to live weight results in more realistic values than relating it to feed intake.
给安装了回肠盲肠再入式套管的生长猪投喂三种含植物蛋白源的日粮和两种无氮日粮。文中解释了消化道中粗蛋白和氨基酸的流动情况，以及肠道各段粗蛋白和氨基酸的表观消化率和真消化率。结果表明，将代谢粪氨基酸的计算与活重相关联，比将其与采食量相关联能得到更实际的值。
