Formulation of concentrated jaggery scum feed blocks for pigs so as to increase the shelf life of concentrate jaggery scum and use in off season. Concentrated jaggery scum (CJS) is an agro-industrial by-product obtained from jaggery production unit but because of its high moisture content and reducing sugars, it gets fermented within few days and not fit for feeding. The present study consists of two different phase: phase ? consist of formulation of concentrate jaggery scum feed blocks with binder or without binder. Two types of natural binder namely multhani mitti and maida were used. Feed blocks without binder were best having sweetish odour, not hard, less crack formation, retention of shape and showed full acceptability by pigs. Phase ?? consist of formulation of CJS feed blocks using 50, 60 and 70% of CJS and of three different shapes i.e. circular, brick and prill. Among different treatment feed blocks, feed block having 70% CJS and of prill shaped can be a very good feed for pigs as it showed best results.
