Abstract
Indonesia faces difficulties in providing grass feed for ruminant livestock. The low quality of wild grass cannot meet nutritional needs, resulting in low livestock productivity. Therefore, many farmers use agricultural waste such as corn stalks and rice straw as alternative feed ingredients. The low nutritional content of rice straw and corn stalks, along with their difficult digestibility, requires treatment to improve their nutritional value. One way to increase their nutritional content is through fermentation. Fermentation is one effort that can be done to improve the nutritional quality of feed through the activity of microorganisms such as yeast. This study aims to evaluate the effect of yeast profiles on fiber quality in fermented feed based on agricultural waste. The study will use a Completely Randomized Design with two treatments: P0 (without any addition) and P1 (with the addition of 5% molasses), each with four replications. The parameters observed include the content of Neutral Detergent Fiber (NDF), Acid Detergent Fiber (ADF), cellulose, hemicellulose, and lignin. The expected results of this research are increased yeast activity that can reduce crude fiber content and improve the quality of feed fiber, so that agricultural waste can be used as an alternative feed that is more efficient and has better nutritional value for livestock.
