Resumo:  脂肪交雑ナンバー(Beef Mabling Standard number, 以下BMSナンバーと略す)判定の際,頭半棘筋および背半棘筋の脂肪交雑程度が,補 助的情報として利用されている.それらの情報を利用することが,画像解析によるBM Sナンバー推定の精度に対する影響を検討した.BMSナンバーを持つ99頭の枝肉横断 面の写真を用い,胸最長筋(胸),頭半棘筋(頭)および背半棘筋(背)に占める 脂肪交雑の面積比,それぞれの筋肉において,脂肪交雑粒子面積を5つの階層に区分 し,算出した粒子面積および形状係数の平均ならびに標準偏差,胸最長筋を4,9,25 および100の小領域に分割したそれぞれの領域における脂肪面積比の標準偏差を,画 像解析形質として算出した.BMSナンバーと各筋肉における脂肪面積比との相関係数 は0.70(胸),0.38(頭),0.39(背)であった.胸最長筋のみの情報を利用した 場合,格付の差(推定BMS?格付員によるBMS)が±0および±1以内であった割合は ,それぞれ52.5,96.0%であったのに対し,頭および背半棘筋の情報を利用した場合 ,64.6,96.0%となった. Marbling level of M. semispinalis capitis (SC) and M. semispinalis dorsi (SD) are used as supplementary information in the Beef Marbling Standard (BMS) number judgment. The effectiveness of the use of these information to predict the BMS number by the image analysis was examined. Images of 99 carcass cross sections with BMS number were used. The fat area ratio on M. longissimus dorsi (LD),SC and SD was calculated as an image analysis trait. Similarly,means and standard deviations of the area and of the form score for marbling particles classified into 5 levels,and standard deviations of marbling percentages in small areas which were obtained by dividing the ribeye into 4,9,25,and 100 partitions were calculated by image analysis. The correlation coefficient among BMS number and the fat area ratio of each muscle were 0.76 (LD),0.38 (SC) and 0.39 (SD). Percentages of the judgment difference(predicted BMS number-BMS number assigned by grader) within士0 and 土1 without consideration of the information from SC and SD muscles were 52.5 and 96.0%,respectively. While percentages of the judgment difference within士0 and 士1 taking into consideration the information from SC and SD muscles were 64.6 and 96.0%,respectively.
