Abstract
This study was conducted to investigate the effect of harvest stage of corn on the quality of gunny bag silage manufactured with corn grown in paddy land of Department of Animal Resources Development, National Institute of Animal Science, RDA from 2009 to 2010. Corn "Kwangpyungok" was harvested at three different growth stages (milk, yellow ripen and ripen stage) and ensiled at each harvest stages. The content of crude protein (CP) of corn in gunny bag silage decreased with delayed harvest maturity, but the contents of ADF (acid detergent fiber), NDF (neutral detergent fiber), TDN (total digestible nutrient) and in vitro dry matter digestibility (IVDMD) were not changed with delayed harvest maturity. The contents of moisture, pH, and the nutritive values at three different harvest stages were not influenced by the method of silage manufacture and inoculant. The content of lactate in corn bag silage at milk stage was significantly increased (P<0.05), as compared with that of round baled corn silage. However, The contents of lactate in corn bag silage at yellow ripen stage and ripen stage were significantly decreased (P<0.05). Flieg's score in corn bag silage manufactured at milk stage increased as compared with that of round baled corn silage, and Flieg's score was hardly influenced by inoculant. Therefore, we suggest that manufacture method of bag silage can be new silage technique to improve the fermentation of corn silage and that smallscale stock farmer could be substituted bag silage for roll bale silage on small farm land.
