This study was carried out to investigate the effects of various regions of sorghum-sorghum hybrid (SSH) silage on nutritive values and qualities of SSH silage. SSH "SS405" was harvested at ripen stage and ensiled. Samples of SSH silage used in this study were collected in three regions (outside, middle and inside). The contents of crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), total digestible nutrients (TDN) and in vitro dry matter digestibility (IVDMD) in SSH silage were not influenced by SSH silage manufacture methods and lactic acid bacteria. The contents of CP in inside region of SSH silage were lower than those of outside and middle regions (p less than 0.05). However, the contents of NDF, ADF and TDN, and IVDMD were not different between the regions of SSH silage. The content of lactic acid in SSH round bale silage was significantly decreased (p less than 0.05), as compared to SSH square bale silage (SB), gunny bag silage (GB) and trench silage (TS). The contents of acetic acid and butyric acid in SSH silage were not influenced by SSH silage manufacture methods and lactic acid bacteria. The contents of lactic acid in inside region of SSH silage were lower than those of outside and middle regions (p less than 0.05). In addition, the contents of lactic acid, acetic acid and butyric acid were not different between the regions of SSH silage. Therefore we suggest that nutritive values and quality of SSH silage were not influenced by regions of sampling collected from these silages.
