Artificial gut models including both the gastric and intestinal phases have been used in poultry research for decades to predict the digestibility of nutrients, the efficacy of feed enzymes and additives, and caecal fermentation. However, the models used in the past are static and cannot be used to predict interactions between the feed, gut environment and microbiome. It is imperative that a standard artificial gut model for poultry is established, to enable these interactions to be examined without continual reliance on animals. To ensure the validity of an artificial model, it should be validated with in vivo studies. This review describes current practices in the use of artificial guts in research, their importance in poultry nutrition studies and highlights an opportunity to develop a dynamic gut model for poultry to reduce the number of in vivo experiments.

几十年来，包括胃期和肠期在内的人工肠道模型已用于家禽研究，以预测营养物质的消化率、饲料酶和添加剂的功效以及盲肠发酵。然而，过去使用的模型是静态的，不能用于预测饲料、肠道环境和微生物组之间的相互作用。必须建立一个标准的家禽人工肠道模型，以便在不持续依赖动物的情况下检查这些相互作用。为确保人工模型的有效性，应通过体内研究对其进行验证。这篇综述描述了目前在研究中使用人造肠道的做法，
