 note = {一種類のタンパク質原料からなる EP 飼料を作製し，マダイにおける飼料の胃内からの消失率を調べた。各 EP 飼料をマダイに経口投与した時の胃内からの消失の早さは，大豆粕＞血粉＞濃縮大豆タンパク質＞コーングルテンミール＞魚粉＞ポークミール EP 飼料の順であり，大豆タンパク質を含む EP の消失率が高い傾向を示したことから，大豆タンパク質は飼料の胃からの消失を早めることが示唆された。さらに，各 EP 飼料のマダイ消化管粗酵素液による消化性を調べたところ，未消化タンパク質の程度は血粉および大豆粕EP飼料で多かった。これらは胃からの消失も早い傾向を示したことから，消化し難い飼料は胃から早く消失する可能性が考えられた。また各 EP 飼料を投与したマダイ血清中トリグリセリド濃度と遊離アミノ酸濃度の変化が飼料により異なることから，脂質やタンパク質の消化吸収に原料タンパク質が影響することが考えられた。, In order to characterize the properties of protein sources, we prepared extruded pellets (EPs) which were composed of only a single protein source: fish meal (FM), pork meal (PM), blood meal (BM), corn meal (CM), soybean protein concentrate (SP), or soybean meal (SM), evaluated the gastric evacuation rate (GER) of red seabream Pagrus major juveniles, and determined the degree of undigested protein of the test EPs with gut enzyme extract. GER was highest in SM diet among the test EPs in order SM>BM>SP>CM>FM>PM diets, and SP diet tended to have a high GER value, suggesting that the soybean protein advances gastric evacuation. BM and SM diets had a low degree of digestion with gut enzyme extract, and this was due to their inhibitory activities. These diets had higher GER, suggesting that a high amount of indigestible protein in the diet may promote gastric evacuation. The concentration of triglycerides and free amino acids in serum of red seabream fed test EPs was measured as an index of absorption of dietary nutrients. The triglyceride and free amino acid levels showed different patterns depending on the protein source. These results suggest that the protein sources influence protein and lipid digestion and absorption., 26252034},
