• The optimal pellet diameter for creep feed is ≥8 mm • Creep feeder quantity and/or design should support concurrent feeding by multiple piglets. • Creep feed intake correlates with litter size, with larger litters consuming more feed per piglet. • The physical form of the feed is more important than the dietary composition. • Further research is needed on diverse feeds aligned with piglets’ natural behavior. Stimulating creep feed intake in piglets is increasingly important due to larger litter sizes, which raise piglet requirements to levels above the sow milk production. Although intake is typically low during the initial weeks, piglets show exploratory behavior (nosing, rooting, and chewing) from the first week of life. Supporting this behavior in conventional farrowing environments can promote early feed engagement. This review highlights strategies to enhance creep feed intake, including housing and creep feeder design, feeding practices, feed characteristics, and management. Creep feeder design and sow confinement (crated vs. loose) affect piglet interaction with feed. Introducing solid feed between 5–10 days after farrowing is recommended. The physical form of creep feed (e.g., meal, pellets, crumbles, thermally processed, or liquid) plays a key role. Pellet diameter is especially important; larger pellets (≥ 8 mm) stimulate feeding behavior. Sensory properties (taste, smell, texture) are less critical in attracting piglets. While dietary complexity can influence intake, high-complexity diets do not always outperform low complexity diets, even though these may contain less ingredients and less refined ingredients. Flavor additives, either in the sow’s diet or the creep feed, may improve palatability and familiarity. Increasing the weaning age is the most efficient tool to increase creep feed intake and reduce the proportion of non-eaters at weaning. In conclusion, a multifactorial approach integrating these elements may be most effective in optimizing early feed consumption and adapting to solid feed before weaning.
