This research explored using mushroom-treated rice straw as an alternative feed for dairy goats, addressing both environmental and economic challenges in agriculture. Instead of burning rice straw, which causes pollution, it can be transformed into nutritious animal feed through mushroom cultivation. The study found that replacing up to 50% of traditional feed with treated rice straw maintained good milk production and actually improved some aspects of milk quality. Impacts on everyday life: • Reduces air pollution by providing an alternative to burning agricultural waste • Offers farmers a cost-effective feed option during feed shortages • Improves the nutritional quality of goat milk for consumers • Creates additional income opportunities through mushroom cultivation • Promotes sustainable agricultural practices by recycling crop residues
