ABSTRACT
Six treatments were formulated to make silages with fish wastes, corn stubble, molasses, pineapple peel (PP) [15, 30 and 45%] and inoculum Lactobacillus sp. or Lactobacillus B2. The silages of each treatment were made in triplicate and incubated at 30 °C for 0, 2, 4, 7 and 14 days in order to evaluate the acidification under a 3 x 2 x 5 factorial design. The chemical composition and in vitro dry matter digestibility (IVDMD) were determined to the silages at end of fermentation. The highest acidification (p‹0.05) was presented in the treatments with PP 15 and 30% and Lactobacillus B2 for 7 days. The highest dry matter content (39.3%) (p‹0.05) was obtained with 15% of PP and the crude protein was from 26.5 to 31% without significant difference. The highest concentration of lipids (9.85%) was present in the treatments with PP 30 and 45% and Lactobacillus B2. Detergent fiber fractions decreased with increasing PP level and the highest IVDMD (82.9%) occurred in silages when using Lactobacillus B2, regardless of PP level. The silages obtained are an alternative in ruminant feeding.REFERENCES
