The effect of dose of chemical additive and temperature of sugar beet pulp on the quality of silage
Sugar beet pulp silages (SBPS) are characterized by a high feeding value. They represent a convenient energy fodder (6.3 MJ NEL/kg dry matter and higher) and have specific effects on rumen fermentation leading to an improved digestibility of the organic mass in the feeding ration. SBPS have higher (up to 35%) enzymatic digestibility then fresh sugar beet pulps (SBP) with positive influence on nutritive value indicators (Zheng 2011, Kilic and Saricicek 2010, Weber et al. 2006ab). Correctly preserved SBP usually have light greyish colour and pleasant smell, but they are very quickly perishable. The speed and the type of microbial processes depend on the moisture content, the composition of SBP, on their microbial cleanness, and on the humidity and temperature of the environment. In agricultural practice, mostly for economic reasons, the SBP are often ensiled without additives and sometimes even with a substantial delay after their dispatch from the sugar factory while stored anaerobicaly in silage bags (Weber et al. 2006ab). In similar experiments with biological inoculants the researchers (Dolezal et al. 2005) found that such practice reduced losses significantly and improved the indicators of fermentation quality (pH and higher contents of lactic acid). Zheng 2011, Kilic and Saricicek 2010 and Weber et al. 2006ab recommended preservation using chemical additives aimed at strengthening of the aerobic stability of SBPS.
