<i>Oncorhynchus mykiss</i> silage improves meat fatty acids profile, blood parameters, intestinal histomorphometry, productive performance, and modulates the cecal microbiota of <i>Cavia porcellus</i>.

ABSTRACT: 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 Oncorhynchus mykiss silage in the diet of Cavia porcellus 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 treatments: T0 (0%), T1 (4%), and T2 (8% silage inclusion in the diet), with 11 replicates each. The inclusion of silage in the diets significantly modified the lipid profile of the meat, increasing monounsaturated fatty acids and docosahexaenoic acid (DHA, C22:6) (p < 0.001) compared to T0. No
