Improving the digestibility value of the feed of banana stems by fermentation using Effective Microorganism 4 (EM4) and Organic Liquid Supplement (OLS)

The use of agricultural waste as animal feed is quite beneficial in obtaining the nutritional needs of livestock. Fermentation of animal feed increases the digestibility of dry matter and organic matter. This study aims to improve the digestibility value of the feed of banana stems by fermentation. The research design used in this study was a complete randomized design with three replications. The treatment is by fermenting the banana stems using two types of starter which include effective microorganism 4 (EM4), organic liquid supplement (OLS) and without a starter. The results showed that the fermentation treatment on a banana stem with starter can increase the digestibility value of the feed by 39% and the fermentation result increases the protein, fat content, and the extract without nitrogen. The EM4 starter provides better results than the OLS.
