Effect of sesame meal supplemented in Sudangrass silage on fermentation quality and feed intake in goats.

摘要

To increase the nutritive value and reduce the moisture content of Sudangrass silage, sesame meal was mixed with Sudangrass at 5, 10, 20 and 40% (w/w) in laboratory glass silos. This silage was compared with plain Sudan grass silage. The acetic acid content increased when sesame meal was added at the level of more than 20% and the content of propionic acid, butyric acid and volatile basic nitrogen (VBN) decreased with increasing sesame meal supplementation. Feed intake of silage mixed with sesame meal and/or beet pulp was higher than that of non-added Sudangrass silage in goats. As the reduction of butyric acid and VBN is an index of good quality silage, it is suggested that sesame meal can be used as an additive to make good silage with improvement of palatability in ruminants..
