Animal production is a significant protein source for human consumption (Salter and Lopez-Viso, 2021). The production of monogastric animals has grown enormously in recent decades, particularly of poultry and swine (Rauw et al., 2020). Such growth is attributed to the progress in animal nutrition, disease control, and genetic improvement in response to the global demand for meat (Kumar et al., 2023) and, of course, the tireless efforts of scientists working in the area for the past decades. Among them is Professor Mingan Choct, a monogastric animal nutritionist at the University of New England. He has dedicated his entire academic career to the field, significantly contributing to monogastric animal research and industry. To honour his contribution and celebrate his retirement, we organized a special issue in Animal Nutrition with contributions from a group of prominent researchers in monogastric animal nutrition and health. In this special issue, we published reviews and research papers, 8 in total, with a focus on the nutrition and health of monogastric production animals.
