Abstract

Obtaining olive oil is associated with a large amount of co-product (olive pomace). Thus, the objective was to evaluate the preservation of the original bromatological characteristics of the olive pomace in two storage times (0 and 48 hours) and to the effect of the addition of commercial inoculant and wheat bran (olive pomace without inoculant; olive pomace with inoculant; olive pomace with inoculant and 15% wheat bran; and olive pomace with inoculant and 30% wheat bran) at the pH of the silage of this co-product. The contents of dry matter (DM), organic matter (OM), mineral matter (MM), ether extract (EE), insoluble fiber in neutral detergent corrected for ash (NDFa), insoluble fiber in acid detergent corrected for ash (ADFa), acid detergent lignin (ADL), crude protein (CP), neutral detergent insoluble nitrogen (NDIN), acid detergent insoluble nitrogen (ADIN), true DM digestibility (TDMD30 and TDMD48), true NDF digestibility (TNDFD30 and TNDFD48), total digestible nutrients (TDN Weiss), non-fibrous carbohydrates (NFC) and soluble carbohydrates (SCHO). The bromatological composition and digestibility of the olive pomace did not differ (P>0.05) in storage times, except for the content of SCHO, which decreased (P<0.05) with 48 hours of storage. In addition, the lowest (P<0.05) pH values ​​were obtained in the silage of olive pomace with inoculant and 30% of wheat bran. The results of this study demonstrate that this co-product can represent a food alternative for increasing energy density in ruminant nutrition.
