Effects of feeding frequency on crystaline methionine utilization was also examined in the rainbow trout (exp-2). Plasma free methionine levels increased in yellowtail fed curdlan coating methionine but the levels did not change in OM fed fish. In the feeding study, despite a good absorption of curdlan coating methionine, growth rate of curdlan coating methionine was inferior to crystalline methionine fed group. No growth difference was noted in fish fed a crystalline methionine supplement group either two or four times feeding a day. These resultssuggested that bioavailability of OM is inferior to curdlan coating methionine. However, the latter product did not give the same growth performance as crystalline methionine.}, pages = {43--48}, title = {Bioavailability of modified forms of methionine in yellowtail and rainbow trout}, volume = {19}, year = {2000} }
