Abstract

Ca2+ concentration in blood plasma and Ca(2+)-ATPase activity in epiphysis of tibia at 3 and 15 weeks of age were compared among three quail lines (LL, RR and SS) selected for body weight. 2. The Ca2+ concentrations in blood plasma were higher in order of LL, RR and SS at 3 and 15 weeks of age in both sexes. Ca2+ concentrations in blood plasma at 3 weeks of age were lower than those of 15 weeks of age in both sexes. 3. At 15 weeks of age, the concentration of females was significantly higher than that of males in all lines. 4. The activities of Ca(2+)-ATPase in epiphysis of tibia was higher in order of SS, RR and LL at both ages and in both sexes. 5. The activities of Ca(2+)-ATPase at 3 weeks of age were significantly higher than those of 15 weeks of age in all lines. 6. These results suggest that the selection for body weight changed the concentration of Ca2+ in blood plasma and the activities of Ca(2+)-ATPase in epiphysis of tibia, parallel to the change of tibia length.

摘要

比较了三个因体重被选育的鹌鹑品系（LL、RR和SS）在3周龄和15周龄时血浆中的Ca2+浓度以及胫骨骨骺中的Ca(2+)-ATP酶活性。2. 在3周龄和15周龄时，两性的血浆Ca2+浓度均按LL、RR和SS的顺序升高。在3周龄时，两性的血浆Ca2+浓度均低于15周龄时的浓度。3. 在15周龄时，所有品系中雌性的浓度均显著高于雄性。4. 在两个年龄阶段和两性中，胫骨骨骺中Ca(2+)-ATP酶的活性按SS、RR和LL的顺序升高。5. 在所有品系中，3周龄时Ca(2+)-ATP酶的活性均显著高于15周龄时的活性。6. 这些结果表明，对体重的选择改变了血浆中Ca2+的浓度以及胫骨骨骺中Ca(2+)-ATP酶的活性，这与胫骨长度的变化平行。
