The feed is the main ingredient in livestock breeding. The selection of good feed will increase livestock productivity. Many feeds can be made from waste. One example is tofu residue. Tofu residue is agro-industrial waste in making tofu. The feed for goats/sheep provided by breeders in Deli Tua Village dominantly utilizes green grass. So it is necessary to make the alternative animal feed based on tofu residue by adding microorganisms such as Aspergillus niger and Rhizopus oryzae in the fermentation process. The methods in this activity are a case study of partner problems, socialization about animal feed, and training on making animal feed. This community service is expected to increase livestock productivity both in terms of quality and quantity.
