Abstract

Abstract: Various unprocessed corn, steam-flaked corn (thickness 1.5 mm, SFC 1.5), and steam-flaked corn (thickness 2.0 mm, SFC 2.0) was used in the present study to compare the chemical compositions, starch gelatinization and ruminal fermentation characteristics in vitro of corn grains as affected by various processing based on chemical analysis, in vitro ruminal fermentation and gas production method. The results showed that the contents of crude protein and ether extract decreased (P<0.05), but the starch gelatinization increased (P<0.05);Gas production rate and starch digestibility of SFC were higher than unprocessed corn (P<0.05), but NH₃-N concentrations were lower (P<0.05);The starch gelatinization of SFC 1.5 (88.76%) increased by 17% than that of SFC 2.0 (71.60%);The gas production rate, the digestibility of dry matter and starch of SFC 1.5 in 4 h significantly increased than that of SFC 2.0 (P<0.05). No differences on 48 h gas production, 12 and 24 h pH, total VFA production, the molar proportion of acetate, propionate, acetate/propionate, isovalerate, isobutyrate and valerate (P>0.05). It was concluded that the various thickness steam-flaked corn grains could increase starch digestibility and degradation rate, slow ruminal ammonia release, but would not affect 48 h gas production and other ruminal fermentation traits.

Key words: steam-flaked corn; in vitro rumen fermentation; nutrients digestibility; fermentation traits
