In recent years, there has been significant attention toward the incorporation of alternative functional feed ingredients in monogastric diets. The objective is to improve sustainability and optimize animal performance both under normal conditions and in heat stress situations. Among these alternatives, Jerusalem artichoke (Helianthus tuberosus L.) has emerged as a promising candidate due to its nutritional composition and potential health benefits. This review aims to investigate the potential utilization of Jerusalem artichoke in monogastric diets and the impact on productive performance parameters. Moreover, the potential prebiotic effects of Jerusalem artichoke on the composition and activity of monogastric gut microbiota are revealed, showing its implications for gut health and reduction in pathogenic bacteria. The incorporation of Jerusalem artichoke in monogastric diets poses several challenges, such as limitation of the dietary inclusion rate. However, there are also future perspectives to consider, such as optimizing processing techniques, evaluating the effects of different cultivars, and exploring potential synergies with other dietary feed ingredients. In summary, this study provides a comprehensive overview of the key findings and unique perspectives on the utilization of Jerusalem artichoke in monogastric diets, highlighting its potential as a valuable feed ingredient.
