TI  - The Effects of Exogenous Fibrolytic Enzymes and a Ferulic Acid Esterase-Producing Inoculant Treatment on Digestibility and Conservation Characteristics of Corn Stover
AB  - The objective of the current study was to determine the effects of a mixed bacterial inoculant possessing ferulic acid esterase (FAE) activityand exogenous fibrolytic enzyme (EFEs) products on the chemical composition, conservation characteristics and digestibility of corn stover. Themoisture level of corn stover was adjusted to 40% with deionized water and then treated with deionized water (control), EFEs (10 U cellulase +60 U xylanase units g-1 of substrate dry matter) or EFEs + FAE inoculant (FAEI) (1.3x105 cfu g-1 fresh forage). The treated stover was then incubatedin laboratory mini-silos for 30 days. After the incubation period, the corn stover treated with both EFEs and EFEs + FAEI had a lower pH, ADF andNDF (P<0.001), and higher acetic acid and lactic acid (P<0.001) than the control stover. In addition, moulds and yeasts were inhibited in stovertreated with EFEs + FAEI. The in vitro true dry matter digestibility (IVTDMD) and in vitro true neutral detergent digestibility (IVTNDFD) of the stovertreated with EFEs and EFEs + FAEI were higher than for the control (P<0.001) but there was no significant difference between the EFEs and EFEs+ FAEI treatments. From economical point of view, the best treatment was EFEs + FAEI. These results suggest that EFEs played a major role inenhancing the digestibility of corn stover, alone or in combination with FAEI. Moreover the use of EFEs + FAEI promoted a positive response in theconservation characteristics.
