The use of rainbow trout silage represents an alternative for the feeding of domestic species such as guinea pigs with a circular economy approach. The objective of this study was to evaluate the effect of <i>Oncorhynchus mykiss</i> silage in the diet of <i>Cavia porcellus</i> on the fatty acid profile of the meat, blood parameters, intestinal histomorphometry, productive performance, and cecal microbiota. Thirty-three weaned male guinea pigs of the Peru breed were used, distributed in three tre
