Sonication to Improve Date Palm Seed Degradability in The Rumen

The main objective of this research was to evaluate the effects of chemical treatment and ultrasound processing (sonication) on the fiber composition and rumen degradability of date palm seeds (DPS). For this purpose, five trials were conducted. In the first trial, the effects of treating DPS with 4% sodium hydroxide (NaOH) at different temperatures (23, 50 and 100 0C) and for different times (30, 60 and 356 min) on seeds fiber content and ruminal degradability were evaluated. Relative to untreated seeds, treated seeds had lower (P<0.05) lignin and hemicellulose, and greater (P<0.05) neutral detergent fiber (NDF), acid detergent fiber (ADF) and cellulose content, particularly at high temperatures. The degradability of seeds organic matter (OM) and NDF were greater (P<0.01) in the treated (41.79 and 35.44%) than untreated seeds (24.71 and 22.77; respectively), particularly when incubated at 23 0C. Treatment time, however, had no effect (P>0.01) on seeds OM and NDF degradability.
