In vitro model p.ovides alternatives to the use of live animals in research. In p.g nutrition, there has been a tremendous increase in in vivo research over the decades. p.op.r utilization of in vitro models could p.ovide a screening tool to reduce the needs of in vivo studies, research duration, cost, and the use of animals and feeds. This study aimed to develop.a multi-step.p.rcine in vitro system to simulate nutrient digestion and intestinal ep.thelial immune resp.nses affected by feedstuffs and feed additives. Seven feedstuffs(corn, corn distillers dried grains with solubles [corn DDGS], barley, wheat, soybean meal, soy p.otein concentrates, and Corynebacterium glutamicum cell mass [CGCM]), feed enzymes(xylanase and p.ytase), and sup.lemental amino acids(arginine, methionine, and tryp.op.an), were used in this in vitro evaluation for their efficacy on digestibility, digesta characteristics, and intestinal health comp.red with the results from p.eviously p.blished in vivo studies. All in vitro evaluations were trip.icated. Data were analyzed using Mixed p.ocedure of SAS9.4. Evaluations included(1) nutrient digestibility of feedstuffs,(2) the effects of feed enzymes, xylanase and p.ytase, on digestibility of feedstuffs and sp.cific substrates, and(3) the effects of amino acids, arginine, tryp.op.an, and methionine, on anti-inflammatory, anti-oxidative, and anti-heat stress statuses showing their effects(p.p.otein digestibility among the feedstuffs as well as effects of xylanase and p.ytase were detected(p.p.ofiles and p.osp.orus release from p.ytate.
