Abstract
Two experiments were conducted to investigate the possibility of sea weed as a pellet binder. Experimental diets were prepared by adding sea weed to a basal diet at the level of 2 and 5%. These diets were nonsteam pelleted by using a labolatory pellet mill (2 HP CPM Model CL-type 2) with a 3/16 inch die.
Three varieties of sea weeds tested certainly improved the pellet quality, namely, productive efficiency, bulk specific weight, pellet hardness and pellet durability index. To obtain the same durability as bentonite (2.5%) or lignin sulfonic acid (2.0%) addition, 3.9% addition of Laminaria diabolica, 9.4% addition of Laminaria longissima or 6.2% addition of Laminaria japonica was needed.
