Great interest has been placed on utilizing organic wastes as fertilizers. A study was conducted on four groups of goats for 45 days to evaluate the nutritive value and utilization of sorghum manured with one of four fertilizers: (i) inorganic (NPK); (ii) garbage (G); (iii) a mixture of garbage and animal excreta (GAE); and (iv) a mixture of garbage and sludge (GS). Nutrients, IVDMD and yields of sorghum were influenced by advancing maturity and types of manures. The sorghum manured with GS attained greater CP and lower NDF and ADL contents. Significant higher intake of sorghum was recorded for goats in GS followed by the NPK groups (71.2 and 68.7 gm DM/kgW0.75, respectively). All goats obtained sufficient amounts of TDN and DCP which slightly exceeded the recommended requirements for maintenance. Animals did not show any digestive disturbance and enzymes of liver function were in normal ranges.
