Abstract

Abstract: Cornstalk silages of two varieties namely Jidan4011(JD4011) and Sidan29(SD29) were prepared with bankersilo. Digestibility and digestion rate (k) of organic cell wall (OCW) of cornstalk silage and cornstalk in the rumen were determined with in vitro method .The potential digestibility of DM and OCW of cornstalk silage was 57.4%, 48.9% for JD4011, and 58.8%,53.9% for SD29, respectively .The k value of OCW was markedly increased by ensiling and the respective value for the two types were 4.52% and 4.85% for the silage and cornstalk of JD4011, and 5.81% and 7.11% for the silage and cornstalk of SD29. The results confirmed that digestibility and digestion rate of OCW in cornstalk were improved by silage fermentation , the cornstalk with high OCW content was selected to make silage.
