Ensiled sugarcane byproducts: A sustainable solution to livestock feeding

Abstract

Sugarcane is one of the most widely grown crops in the world, primarily cultivated for sugar and bioethanol production. A large portion of the sugarcane plant, including leaves, tops, and bagasse, remains unutilized or is discarded, contributing to agricultural waste and environmental pollution. Recent developments in agricultural sustainability have drawn attention to the potential of converting sugarcane byproducts into valuable feed for livestock. One promising solution is the conversion of these byproducts into silage, which can serve as a sustainable feed option for livestock, particularly in tropical and subtropical regions where sugarcane is widely grown. Sugarcane byproduct silage not only reduces agricultural waste but also provides a cost-effective, high-fiber, and carbohydrate-rich feed for ruminants, contributing to more efficient livestock production. However, challenges such as low protein content, fermentation quality, and proper storage conditions must be addressed to optimize its nutritional value. This review explores the potential of sugarcane byproduct silage as an innovative approach to livestock feeding and waste valorization. By improving fermentation techniques and promoting proper storage, sugarcane byproduct silage can become a sustainable way forward. This review examines the nutritional value, production methods, uses, and constraints of sugarcane byproduct silage, offering an in-depth discussion of its role in sustainable agricultural practices.
