The objective of this study was to determine the performance and carcass fatty acid profile of guinea pigs raised under three feeding systems. For this, 18 21-day-old male guinea pigs were used individually housed randomly in galvanized cages. Each guinea pig was an experimental unit. Six guinea pigs received one of the following treatments: T1, only green alfalfa; T2, Mixed feeding (concentrate feed “Cuy Mixto La Molina“ + green alfalfa (10% BW)); and T3, Integral feeding (only concentrate feed “Cuy Integral La Molina“). The experiment lasted 28 days. Weight gain, feed intake and feed conversion were measured weekly. At the end of the evaluation period all animals were killed to assess carcass yield. Carcass was then processed to extract the total fat and determine the fatty acid profile by gas chromatography. The recorded data were subjected to analysis of variance under the Completely Random Design. The productive performance and fatty acid profile of the carcass of experimental animals were significantly influenced (p <0.05) by the dietary treatments. That is, guinea pigs fed the T1 had lower feed intake, lower weight gain, higher feed conversion and lower carcass yield than the animals that received the other two treatments (T2 and T3). However, they had carcasses with the highest content of omega-3 in particular α-linolenic fatty acid and lower content of omega-6, resulting in a lower n-6/n3 fatty acid ratio and the lowest carcass fat content. In conclusion, this study shows that Medicago sativa is a source of n-3 fatty acids, particularly α-linolenic acid which can improve significantly fatty acids n-3 content of the carcasses.
