Glycerol monolaurate (GML) is naturally present in breast milk as well as other natural sources such as coconut oil and is widely used as a food additive. Dietary α-GML is used in animal production due to its safe-guarding health and growth-promoting effects. In the present study, α-GML was evaluated for growth performance, blood parameters, and intestinal health in piglets. Dietary α-GML helped piglets digest dry matter, crude protein, ether extract, and gross energy in feed. The blood parameters and intestinal structure of piglets fed the diet containing 1,000 mg/kg α-GML were improved. In addition, α-GML supplementation promoted the colonization of beneficial bacteria and inhibited the number of harmful bacteria. In the current study, dietary α-GML was responsible for improving the health status, intestinal morphology, and digestion and absorption of nutrients of weaned piglets with less diarrhea.
