Ensiling as a Conservation Technique for Opuntia ficus indica (L.) By-Products: Peel and Pastazzo

Italy is the third largest producer of Opuntia fruits in the world after Mexico and the United States, and 97.72% of these fruits produced by Italy are grown in Sicily.

In this study, ensiling was chosen to preserve prickly pear peels (PPPs) and “pastazzo” (PPS) mixed with 12% wheat bran.
