| Abstract | The objective was to study the effects of using yeast (Saccharomyces cerevisiae)-fermented corn cobs and husks to replace rice bran in beef cattle diets on gas production kinetics and in vitro degradability. Plan a complete randomized design (CRD) by dividing the trial group into 11 trial groups. Each experimental group used a different ratio of rice bran to yeast-fermented corn cobs and husks (RB: YCCH): 100:0 (control group), 90:10, 80:20, 70:30, 60:40, 50:50, 40: 60, 30:70, 20:80, 10:90, and 0:100% (DM), with 3 replicates per experimental group. The results of the study found that the nutritional value of corn cobs and husks fermented with S. cerevisiae yeast increased, as did crude protein (CP) and ether extract (EE). Moreover, it can cause a decrease in fiber, such as neutral detergent fiber (NDF) and acid detergent fiber (ADF). When testing gas production kinetics, it was found that the values of the immediately soluble fraction (a), insoluble fraction (b), gas production rate (c), and potential extent of gas production (a+ b) were significantly different statistics between treatments (P < 0.01). The group with the highest a-value is group T6 (-0,95), and the lowest value is Group T10 (-6,06). The highest b-value is group T10 (138.03), and the lowest value is group T6 (110.37). The c-value is the highest value in group T7 (0.023), and the lowest value was in group T6 (0.014). The a+ b value was highest in group T8 (132.11), and the group with the lowest value was T6 (109.42). For in vitro dry matter degradability (IVDMD) and in vitro organic matter degradability (IVOMD), both at hours 12 and 24, there were no statistical differences (P > 0.05). From this study, it can be concluded that the use of yeast-fermented corn cobs and husks in place of bran in food recipes can be used up to 100% by affecting the kinetics of gas production but not the in vitro degradability. |
