Effects of Urea, Molasses and Urea plus Molasses supplementation to sorghum Silage on the silage quality, in vitro organic matter digestibility and metabolic energy contents

Abstract

Silage type sorghum harvested at milk stage were ensiled for 70 days with no additive or differing levels of Urea (U), Molasses (M) and Urea+Molasses (U+M) to determine silage quality, in vitro organic matter digestibilities (IVOMD) and metabolic energy contents (ME). According to physical properties, all silages are either excellent or satisfactory. While addition of urea decreased organic matter digestibilities and metabolic energy contents of the silages, it was not negatively affect fermentation quality. It has been noted that it is possible to produce high-quality silages with all of the additives and 0.5U%+5M% addition into silages produced the best quality silages in terms of fermentation quality criteria, organic matter digestibility and metabolic energy contents. © 2007 Asian Network for Scientific Information.
