 note = {モンゴル国における優良ヤギ品種の確立を目的としてカシミヤ毛生産関連遺伝子のクローニングを試みている。その研究対象のリソース・ファミリーとしてBayandelger(BD),Gobi Gurvan Saikhan(GGS)およびZalaajinst White(ZW)の3集団をモンゴル国内に維持している。今回,本ヤギ集団における体重の加齢および季節的変動,並びにカシミヤ毛生産量からそれらの品種特性を調査した結果,以下の成績が得られた。1. GGS, ZW, BD集団の同一個体の冬季間における体重の損耗率を比較した結果,4歳齢の春にはGGSとZW集団には有意差は認められなかったが,この2集団とBD集団間に有意差が認められた(p<0.05～0.01)。体重損耗率はBD集団で最も低く23.70%で,次いでGGS集団の24.90%であった。最も体重の重かったZW集団は冬季間の損耗が36.06%で3集団の中で最も大きかった。2. GGS, ZWおよびBDのカシミヤ毛生産量は,それぞれ333.11±8.32g, 268.07±12.30gおよび222.86±5.32gであった。カシミヤ毛の直径は16-19,15-16.5および12-15μmであることから,BD集団のカシミヤ毛が最も細く,毛色形質を考慮すると優良な品種と判断された。冬季間の体重損耗率が最も少ないのは,細い毛による体温保温効果と関係しているものと推察された。3. BD集団におけるカシミヤ毛の長さ(5.68±0.39cm),直径(16.53±0.10μm)および毛生産量(222.86±5.32g)のそれぞれの間における相関では,長さと生産量の間に強い相関(0.747)が認められた。, To establish excellent goat breeds in Mongolia, we have performed the cloning of genes related to cashmere production. As a genetic pool for this purpose, we have maintained Bayandelger (BD), Gobi Gurvan Saikhan (GGS), and Zalaajinst White (ZW) in Mongolia. In this study, the breed traits of the 3 goat populations were evaluated based on age-related and seasonal changes in body weight and cashmere production, and the following results were obtained. 1. Weight loss during winter was compared among individuals in the GGS, ZW, and BD populations. No significant difference was noted between GGS and ZW, but a significant difference was observed between the two populations and BD (p<0.05-0.01) in spring at the age of 4 years. Weight loss was the lowest in BD (23.70%), followed by GGS (24.90%). The heaviest ZW showed the greatest weight loss during winter (36.06%) among the 3 populations. 2. The cashmere yields in GGS, ZW and BD were 333.11±8.32, 268.07±12.30, and 222.86±5.32g, respectively, and the cashmere diameters in these populations were 16-19, 15-16.5 and 12-15μm, respectively. Therefore, considering the hair color trait, BD, with the thinnest cashmere, may be an excellent breed. The lowest weight loss during winter seen in this population may be associated with the heat-retaining effects of the thin cashmere. 3. In BD, the correlation coefficients between cashmere length (5.68±0.39cm) and production (222.86±5.32g), and between cashmere diameter (16.53±0.10μm) and production were 0.747 and 0.137, respectively, showing a marked correlation between length and production., E, 12, KJ00005590699, 短報, Note},
