笼养丹顶鹤成体与亚成体血液生理生化指标比较

Physiological and Biochemical Indexes of Blood in Adult and Sub-adult Captive Red-crowned Cranes

为了揭示丹顶鹤(Grus japonensis)不同年龄和性别个体之间血液生理生化指标的差异性,对沈阳动物园42只笼养丹顶鹤(成体24只,亚成体18只)的15项血液生化指标和13项血液生理指标进行了比较。所测得的血液生理生化指标在不同性别之间不存在显著差异(P>0.05)。血清肌酐成体(37.05±17.03)mmol/L、亚成体(22.57±11.68)mmol/L,血清尿酸成体(878.22±514.41)mmol/L、亚成体(426.17±207.74)mmol/L,血清甘油三酯成体(7.73±4.75)mmol/L、亚成体(3.51±4.07)mmol/L,这3项指标均为成体高于亚成体,差异性显著(P<0.05)。这几项指标的变化表明,丹顶鹤在成体和亚成体时期采取了相同或不同的生态适应策略。

In order to explore the age and sex differences in physiological and biochemical indexes of blood in Red-crowned Cranes（Grus japonensis）, 13 physiological indexes and 15 blood biochemical indexes were determined and compared using samples from 42（adult 24, sub-adult 18） captive Red-crowned Cranes at the Shenyang Zoo. The results showed that all the indicators had no significant difference between the sexes（P〉0.05, Table 1 and 2）, but there were significant differences in the serum creatinine（adult 37.05 ± 17.03 mmol/L, sub-adult 22.57 ± 11.68 mmol/L）, serum uric acid（adult 878.22 ± 514.41 mmol/L, sub-adult 426.17 ± 207.74 mmol/L）, and serum triglyceride（adult 7.73 ± 4.75 mmol/L, sub-adult 3.51 ± 4.07 mmol/L） indicators between adult and sub-adult（Table 3 and 4）. This implies that the Red-crowned Crane might adopt the same or different ecological adaptation strategies in different adult and sub-adult periods.
