The study evaluated the effect of the fish silage on feed rations for the Guinea Pig (Cavia porcellus). 80 Peruvian line (1/2 blood) guinea pigs, weaned at 14 ± 3 days of age, were used. The treatments consisted of different levels of fish silage: 0 (D0), 10 (D10), 20 (D20)and 30% (D30). The study lasted 10 weeks and was divided in three stages: 0-42, 42-70 and 0-70 days. Body weight gain and instake was higher in D10, D20. and D30 as compared to DO, (p<0.05) whereas no differences were found between D10, D20 and D30. For all stages, food conversion was high in D20 and D-30. The carcass performance was better in D-30 and the economic benefit was better in D-20. The organoleptic trial suggested that meat' flavor and smell were affected on D-20. It was concluded that the use of fishsilage in the rations, improved the productive performance of the guinea pig, where 20% content was the most appropiate bse dón organoleptic and economic terms being viable.
