The objective of this study was to evaluate the effect of various additives on the nutritional value and aerobic stability of safflower (Carthamus tinctorius L.) silages. Silages were prepared from whole safflower plants harvested 102 days after planting, which were chopped to a particle size of 2.0 ± 0.5 cm and fermented for 120 days in polyvinyl chloride microsilos (6" × 46 cm), evaluating the following treatments: (1) safflower silage (SS) without additives, (2) SS supplemented with Guanacaste tree (Enterolobium cyclocarpum) pod meal, (3) SS supplemented with corn meal, (4) SS supplemented with sorghum meal, (5) SS supplemented with molasses, (6) SS supplemented with homofermentative inoculant, and (7) SS supplemented with fermentative inoculant + molasses. Compared with SS without additives, the addition of all the evaluated additives increased (p < 0.0001) the crude protein content and the relative forage value, while simultaneously decreasing the pH in SS. In contrast, the use of Guanacaste tree pod meal, corn, and sorghum decreased (p < 0.0001) the neutral detergent fiber and acid detergent fiber contents, while simultaneously increasing (p < 0.0001) the in vitro digestibility of dry matter in SS. All the evaluated additives increased (p < 0.05) the aerobic stability of the SS, which broke 42 h after opening the microsilos, whereas the silage without additives broke at 30 h. In conclusion, the use of Guanacaste tree pod meal, corn, and sorghum as additives improves the nutritive value and aerobic stability of safflower silage. [ABSTRACT FROM AUTHOR] |
