We studied the effect of feeding young growing pigs a semisynthetic diet containing 7.5% white kidney beans-germinated (GB), pancreatin treated (PTB), or untreated (raw beans RB)--on protein and amino acid (AA) digestibilities at the terminal ileum. Eleven castrated male pigs (12.2 kg live weight) fitted with a post-valve T-cecal cannula and two blood catheters were used. The 15N-isotope dilution method was used to determine the amount of endogenous protein passing the terminal ileum and the true ileal protein digestibility. Ileal crude protein losses in pigs fed the RB, GB, and PTB diets were 51.9, 27.4, and 51.1 g/kg of DMI, respectively. The total amounts of AA passing the terminal ileum of the pigs fed the RB, GB, and PTB diets were 48.6, 21.4, and 42.2 g/kg DMI, respectively. The apparent ileal crude protein and AA digestibilities of the RB, GB, and PTB diets were 74, 87, and 75% and 76, 89, and 78%, respectively. True ileal protein digestibilities were 88, 93, and 93% for the RB, GB, and PTB diets, respectively. On the basis of this research, germination of white kidney beans improves the digestion of protein by decreasing the content of bean antinutritional factors and increasing the bean true ileal protein digestibility.
我们研究了给幼龄生长猪饲喂含有7.5%白芸豆的半合成日粮的效果，白芸豆分别为发芽的（GB）、经胰蛋白酶处理的（PTB）或未处理的（生豆RB），以观察其对回肠末端蛋白质和氨基酸（AA）消化率的影响。选用11头去势雄性猪（体重12.2 kg），安装了回盲瓣后T型盲肠插管和两根静脉导管。采用15N同位素稀释法测定通过回肠末端的内源蛋白量和回肠真蛋白消化率。饲喂RB、GB和PTB日粮的猪回肠粗蛋白损失分别为51.9、27.4和51.1 g/kg干物质采食量（DMI）。饲喂RB、GB和PTB日粮的猪通过回肠末端的AA总量分别为48.6、21.4和42.2 g/kg DMI。RB、GB和PTB日粮的回肠表观粗蛋白和AA消化率分别为74%、87%和75%以及76%、89%和78%。RB、GB和PTB日粮的回肠真蛋白消化率分别为88%、93%和93%。基于本研究，白芸豆发芽通过降低豆类抗营养因子含量和提高豆类回肠真蛋白消化率来改善蛋白质消化。
