Effect of pineapple peel on acidification kinetics, chemical composition and in vitro digestibility of corn silage. Animal Nutrition and Feed Technology, 22: 41–54. The objective of this study was to evaluate the effect of adding pineapple peel (PP) (0, 5, 10, 20 and 40%) to corn plants of two harvests PM1 (28% DM) and PM2 (34% DM), on silage fermentation, chemical composition and in vitro dry matter digestibility (IVDMD). Mini silos of 250 g were prepared in plastic bags and kept at room temperature (25±2°C) for 0, 30, 45, 90 and 150 days (T) under a 2 x 5 x 5 factorial design. PM1 silages with PP (5–40%) at 90 days had the highest acidification (P<0.05); however, silages from all treatments were preserved for 150 days. The DM content was lower (19.24%) in PM1 (PP 40%) silage; however, PP inclusion did not affect the DM content (21.54–24.17%) of the other treatments (P<0.05). Ash (5.54%) and crude protein (7.99%) content were similar (P>0.05) between treatments, while lipid content (3.58%) was greater in PM1 (PP 5%, T 150) silages. PP addition (10–40%) decreased the neutral detergent fiber to 60.07% in the silages, while the acid detergent fiber did not change (average 30.17%). The silages of PM1 and PM2 added with 20 and 40% of PP; respectively, presented the highest IVDMD (78.97%). It is concluded that pineapple peel is a potential ingredient to apply in corn silage production because it contributes fermentation and preservation, in addition does not affect protein content and increases digestibility.
