Effect of Ensiling Rice Straw With Sodium Hydroxide and Lactobacillus plantarum Added Corn Silage and Sugar Beet Pulp on Nutritional Value and In Vitro Digestibility

This research was planned to determine the silage making ability and to investigate the effect of adding Corn Silage (CS) and Fresh Sugar Beet Pulp (FSBP) to rice straw on digestibility. Six main groups were created within the scope of this research. CS was used in 3 groups and FSBP was used in 3 groups. No additives were added to the control group. NaOH was added to a group containing CS and FSBP, and Lactobacillus plantarum (L. plantarum) was added to a group. The samples were left to ferment for 60 days. After fermentation, the groups were analyzed. The samples were then incubated in the Daisyıı incubator for 72 hours. After in vitro digestion, the same analyses were repeated on the samples to determine the in vitro digestion levels. It was observed that the addition of NaOH to the silage samples increased the Dry Matter (DM) digestibility. Crude protein (CP) digestibility was found to be higher in the groups containing FSBP, than in the groups containing CS. In vitro digestion experiments showed decreases in Neutral Detergent Fiber (NDF) and Acid Detergent Fiber (ADF) levels. It was observed that the highest NDF digestion occurred in the groups containing NaOH. In the study, it was observed that NDF and ADF digestion was higher in the FSBP groups. It was observed that rice straw had higher digestibility in the FSBP groups.
