This review summarized for the first time the nutritional benefits of Hibiscus rosa-sinensis in animal feed. the agronomic characteristics for the hyperproduction of Hibiscus rosa-sinensis were reported, as well as the chemical composition of the forage meal (leaves + petioles + stems), with emphasis on crude protein, amino acids, minerals, neutral detergent fiber, acid detergent fiber, lignin detergent acid, secondary metabolites, and metabolizable energy for ruminants and non-ruminants. Additionally, their medicinal properties such as antimicrobial, antifungal, antiparasitic, antioxidant, anti-inflammatory, antidiarrheal, and antipyretic properties were detailed. Its use as a source of protein in ruminant feeding is attractive and can be combined with grasses. In rabbits, fresh forage in high concentrations in the diets reduces the feed palatability, which causes a decrease in animal response, although it depends on the forage quality. In addition, limits for Hibiscus rosa-sinensis forage were recommended in diets or feeding systems for poultry, pigs, rabbits, goats, and sheep.
