Description Five samples of sea weeds, viz. Kappaphycus alvarezii, VIva lactuca-I and Graci/aria corticata-I, Graci/aria corticataII and Sorgassum wightii were collected from Mandapam, Tamil Nadu and Kerala coast and 2 samples of Gracilaria verrucosa, and VIva lacfuca-II were collected fronl Chilka Lake of Orissa respectively. These were analysed for macroandmicro- nuttients respectively. The values for dry matter ranged from 80.95 (VIva lacfuca-II) to 94.42% (Kappaphycus alvarezii), organic matter from 34.95% (VIva lactuca-II) to 89.94% (VIva lactuca-I), crude protein frOITI 7.94% (Kappaphycus alvarezii) to 21.12% (Viva lactuca-II), ether extract from 0.43% (Gracilaria corticata-II) to 2.81% (Sol~~assum lvightii) and crude fibre from 2.42% (Viva lactuca-II) to 13.28% (Sorgassum wightii), respectively. The NDF, ADF and ADL contents were also analysed. Acid insoluble ash content varied from 0.79% (Graci/aria corticataII) to 40.260/0 (VIva lactuca-II from Chilka lake of Orissa). Ash content was very high in both VIva lactuca-II (65.05%) and Kappaphycus alvarezii (47.46%) while lowest was in Ulva lactuca-I (10.06%). Most sea weeds are good source of calciunl, sulphur, manganese, and other trace elements like iodine and iron. Especially Graciaria verrucosa (3404.67 ppm)~ VIva lactuca-I and VIva lactuca-II (1260,1596 ppm, respectively) contained very high amount of iron. Invariably all the species contained high amount of iodine also ranging from 2.93 ppm (VIva lactuca-I ) to 125 ppm (Sorgassum, wightii) than the available iodine content in normal feed. Copper was not detectable in most of the sample analysed. Phosphorus was low while magnesium relnained in good quantity in all the sea weeds. Based on the above results, it is concluded that sea weeds 11lay be used as a potential animal feed both as protein and mineral supplements in ruminant rations to fulfil the gap of deficiency of feed resources and nutrients availability in the country.
