Utilisation of Roselle (Hibiscus Sabdariffa, L) By-Products as Roughage Feed for Sheep

Roselle (Hibiscus sabdariffa, L.) is cultivated for the calyces, which are used for making roselle juice, a drink known to be high in vitamin C. The leaves are also used as a pot herb and some varieties are grown for their fibre. Roselle pods and seeds are by-products obtained after the calyces a...
