Abstract

Dried rice, an organic waste recycling product, is made from dried rice leftovers. With a carbohydrate content nearly equivalent to corn but at a lower price, it has potential as an energy-generating feed, especially in poultry farming. The nutrient content and price of dried rice were evaluated to assess its efficiency for animal feed use. Dried rice samples from three areas in East Java, Indonesia, were analyzed for moisture, ash, crude protein, crude fat, and crude fiber content. Additionally, this research assesses the effectiveness of dried rice as a corn substitute in broiler feed by observing its impact on feed intake, average daily gain, feed conversion ratio, and broiler performance index. Proximate analysis showed insignificant differences among treatments, with moisture content ranging 12.45–12.71%, ash content 0.55–1.31%, crude protein 10.34–10.64%, crude fat 0.12–2.48%, and crude fiber from 0.81 to 1.55%. Although all samples were assessed as efficient, products from Lumajang and Pasuruan were preferred for feed production due to their similarity to corn nutrient content. Dried rice costs approximately USD 213–228 per ton, significantly lower than corn. Dried rice production reduces both organic waste and poultry production costs concurrently, serving as a sustainable waste management model in Indonesia and other rice-producing countries, shifting towards a bioeconomy from a linear economy.
