Chhay Ty; Khieu Borin; Preston, T. R., 2007. Effect of mixtures of water spinach and fresh water hyacinth leaves on growth performance of pigs fed a basal diet of rice bran and cassava root meal. Livest. Res. Rural Dev., 19 (12)

Twenty four crossbred castrated male pigs with initial body weight from 13.7 to 15.1 kg were allocated to 6 diets containing water spinach at levels of 0, 5, 10, 15, 20 and 25% in DM, replacing fresh leaves of water hyacinth at levels of 37, 32, 27, 22, 27 and 12% in DM. The other components of the diet (DM basis) were fish meal (4-5%), soybean meal (4-5%), rice bran (26-27%) and cassava root meal (26-27%). The experiment period was 120 days. The replacement of 37% fresh leaves of water hyacinth by 12% water hyacinth leaves and 25% fresh water spinach (from 37 to 12% of DM) with fresh water spinach (from 0 to 25% in DM) led to: (i) a 50% increase in DM intake; (ii) tripling of the rate of weight gain (from 78 to 215 g/day); and (iii) improved DM feed conversion (from 9.2 to 4.4). It is concluded that there are no apparent benefits from including water hyacinth leaves in diets of growing pigs.
