ABSTRACT

Simple Summary In intensive production systems piglets are weaned prematurely to improve productivity. Early weaning causes stress that directly damages intestinal health and ultimately results in suboptimal growth. Certain dietary additives have shown to improve fat digestion and nutrient absorption helping piglets overcome the negative consequences of early weaning. In our study we evaluated the effects of including an emulsifier, glyceryl polyethylene glycol ricinoleate (GPGR), in the diet of weaned piglets under commercial rearing. A total of 380 animals were assigned to either a control group (fed regular diet) or a GPGR group (fed regular diet supplemented with GPGR). We assessed the morphology of the intestinal epithelium, digestive enzymes activity, and gut microbiota composition as indicators of intestinal health. The piglets fed GPGR showed improved epithelial morphology, superior digestive enzymes activity, and a more balanced microbial community compared to control piglets. Our findings demonstrate that the incorporation of GPGR to the post-weaning diet supports intestinal health and can be used as nutritional strategy to enhance the adaptation of piglets to this challenging period.
