Chemical analysis of water hyacinth LPC (leaf protein content) showed that it is low in Mg, Mn and Zn and border line in P and Na. The carotene content was reduced remarkably from 584-667 ppm in fresh leaves to 91-103 ppm in the LPC. As a major source of protein, it is limiting in methionine and border line in histidine, arginine and lysine. The metabolizable energy and protein decreased significantly with increasing LPC in the diet to as much as 48% in a 100% substitution of SBOM in the control diet. Feeding during the starter period (0-4 weeks) followed by the control diet in the finishing period (5-8 weeks) gave better performance than straight feeding (0-8 weeks) or feeding of LPC diets during the finishing period. The study suggests that water hyacinth LPC at a level not greater than 15 to 16% of the total diet can be econoically viable if cost of production can be reduced to 5% or more
