SOUSA, Luciano Fernandes et al. Bromatological composition and kinetics of rumen fermentation for feeds containing babassu residue. Rev. Ciênc. Agron. [online]. 2014, vol.45, n.1, pp.177-185. ISSN 1806-6690.  http://dx.doi.org/10.1590/S1806-66902014000100021.

The objective of the experiment was to demonstrate the bromatological composition, and evaluate the fermentation kinetics and effective ruminal degradability in vitro, using the "Hohenheim Gas Test" technique, of babassu mesocarp flour I® and II® (FMBI and FMBII) and of feeds at different levels of inclusion. Two trials were carried out: one of pure byproducts and corn, and another of feeds with inclusions of FMBI and FMBII in the following proportions: 0, 7.5, 15.0 and 22.5% of the total dry matter. The experimental design was of randomized blocks, with six blocks in the first trial and five in the second. Measurement times for the gases produced were 3, 6, 9, 12, 24, 48, 72 and 96 hours. The FMBI and FMBII flours showed different bromatological composition for the fibre components (FDN, FDA and Lignin). The FMBI and FMBII flours also showed patterns for fermentation kinetics inferior to the fermentation patterns of corn grain. Increasing the ratio of FMBI and FMBII in the feed reduces gas production for time of incubation. In view of the above, it can be said that mesocarp flours I and II, despite being sources of starch, did not present ruminal fermentation similar to corn grain, the standard source of starch.
