Abstract
Rice straw has the potential to be used as a raw material for making alternative feed for livestock. The implementation of alternative feed is one solution to overcome the urgent problem of feed shortages for ruminants, especially cattle. Total Mixed Ration (TMR), commonly known as complete feed, is a type of mixed feed consisting of several feed ingredients such as concentrates, forage, and other feed ingredients, providing complete nutritional content. This study aims to evaluate the physical quality (aroma, color, texture, pH, temperature, and presence of fungi) and nutritional content (crude protein, dry matter, and organic matter) of fermented TMR using rice straw with different ratios of rice straw and concentrate. The study was conducted at the Sumber Sekar Field Laboratory and the Nutrition Laboratory of the Faculty of Animal Science, Brawijaya University. The study used a completely randomized design (CRD) with 4 treatments and 4 replicates, namely T1= rice straw 80% : concentrate 20% added 4% Saccharomyces cerevisiae, T2= rice straw 70% : concentrate 30% added 4% Saccharomyces cerevisiae, T3= rice straw 60% : concentrate 40% added 4% Saccharomyces cerevisiae, and T4= rice straw 50% : concentrate 50% added 4% Saccharomyces cerevisiae. The analysis results showed that the fermented total mixed ration based on rice straw had a significant effect (P<0.05) on physical quality (aroma, color, texture, pH, temperature, and presence of fungi). In nutritional content, the highest crude protein content is T2, with a crude protein content of 12.25%. The highest dry matter content is found in T2, with a dry matter content of 88.67%. The highest organic matter content is found in T2, with an organic matter content of 66.08%. Treatment T2 is the best total mixed ration based on rice straw, producing the highest crude protein, dry matter, and organic matter content.
