Eksojen Fibrolitik Enzim ve Ferulik Asit Esteraz Üreten Bakteriyal İnokulant Muamelesinin Mısır Samanının Sindirilebilirliği ve Konservasyon Özellikleri Üzerine Etkileri

Bu çalışmanın amacı, ferulik asit esteraz üreten bakteriyel inokulant (FAEI) ve ekzojen fibrolitik enzimlerin (EFEs) mısır samanının kimyasal kompozisyonu, konservasyon özellikleri ve sindirilebilirliği üzerine olan etkisini araştırmaktır. Mısır samanının nem içeriği deiyonize su ile %40’a ayarlandı ve daha sonra deionize su (kontrol), EFE’s (10 U cellulase + 60 U xylanase units g-1 of substrate kuru maddesi) ve EFEs + FAEI (1.3x105 cfu g-1 taze kaba yem) ile muamele edildi. Muamele edilen mısır samanı, 30 gün süreyle laboratuvar mini-silolarında inkube edildi. İnkubasyon periyotundan sonra, EFEs ve EFEs + FAEI ile muamele edilen mısır samanının ADF, NDF miktarı ve pH kontrole kıyasla daha düşük (P

The Effects of Exogenous Fibrolytic Enzymes and a Ferulic Acid Esterase-Producing Inoculant Treatment on Digestibility and Conservation Characteristics of Corn Stover

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
