The primary goal of making silage is to maximize preservation of original nutrients in the forage crop for feeding at a later date. Unfortunately, fermentation in the silo is an uncontrolled process that usually leads to less nutrient preservation. In order to assist in the fermentation process, various silage additives have been used to improve the nutrient and energy recovery in silage, often with subsequent improvements in animal performance. One method which has been successfully used is inoculating silage with a specially selected lactic acid bacterium (LAB) which is known to process good silage making qualities. This study is focused on some practical aspects of the fermentation process and the uses of silage additives containing lactic acid bacteria (ECOSYL AND BIOTAL).
