Abstract

ABSTRACT This study was performed to investigate the effects of various parts of sorghum-sorghum hybrid (SSH) silage on nutritive values and qualities of SSH round bale silage and trench silage. SSH “SS405” was harvested at heading stages and ensiled. Samples of SSH silage used in this study were collected in three different parts (outer, middle and inner). The contents of crude protein (CP) and neutral detergent fiber (NDF), and in vitro dry matter digestibility (IVDMD) in SSH round bale silage showed trends similar to SSH trench silage. However, the contents of acid detergent fiber (ADF) and total digestible nutrient (TDN) in SSH trench silage appeared slightly an increased trend, as compared to SSH round bale silage. The contents of CP in inner parts of both SSH round bale silage and trench silage were lower than those of Outer and middle parts (p<0.05). However, The contents of NDF, ADF and TDN, and IVDMD were not different between the parts of SSH silage. The content of lactic acid in SSH round bale silage was significantly decreased (p<0.05), as compared to SSH trench silage. The content of acetic acid appeared an decreased trends, but there is not significantly different between SSH round bale silage and trench silage. In addition, the contents of lactic acid, acetic acid and butyric acid were not different between the parts of SSH silage.(
