The aim of this study was to investigate the effects of crate type (particularly its height) on selected biochemical indices in captive-reared mallards (Anas platyrhynchos). The physiological changes in response to 2-h crating in crates of either 20 cm or 26 cm height were monitored in 6-week-old mallards. Plasma corticosterone concentrations showed an increase (P = 0.036) in mallards crated in crates of 26 cm height in comparison with control non-crated birds, whereas no difference in plasma corticosterone levels was found between mallards crated in crates of 20 cm height and control non-crated birds. Lower concentrations of plasma triglycerides (P < 0.05) and uric acid (P < 0.05) were found in crated mallards in comparison with control non-crated birds; the height of the crates had no effect. Mallards crated in crates of 26 cm height also exhibited a higher (P = 0.032) plasma lactate dehydrogenase concentration in comparison with control non-crated birds, whereas no difference (P > 0.05) was found in lactate dehydrogenase concentrations in mallards crated in crates of 20 cm height. Our results suggest that crating mallards in lower crates (20 cm) may be less stressful than keeping them in crates allowing vertical movements of the birds.
本研究的目的是调查饲养箱类型（特别是其高度）对圈养绿头鸭（Anas platyrhynchos）选定生化指标的影响。在6周龄的绿头鸭中监测了其在20厘米或26厘米高的饲养箱中被关入2小时后的生理变化。与未关入饲养箱的对照鸟相比，关入26厘米高饲养箱的绿头鸭血浆皮质酮浓度有所升高（P = 0.036），而关入20厘米高饲养箱的绿头鸭与未关入饲养箱的对照鸟之间血浆皮质酮水平没有差异。与未关入饲养箱的对照鸟相比，关入饲养箱的绿头鸭血浆甘油三酯（P < 0.05）和尿酸（P < 0.05）浓度较低；饲养箱高度没有影响。与未关入饲养箱的对照鸟相比，关入26厘米高饲养箱的绿头鸭血浆乳酸脱氢酶浓度也更高（P = 0.032），而关入20厘米高饲养箱的绿头鸭乳酸脱氢酶浓度没有差异（P > 0.05）。我们的结果表明，将绿头鸭关入较低的饲养箱（20厘米）可能比将它们关入允许鸟类垂直活动的饲养箱压力更小。
