Ante-mortem studies of stress in rabbits are few and can potentially impact the haematologic response and physicochemical parameters of muscle meat. The aim of this study was to investigate the induction of stress by transport and simulation at two different times. Two hundred rabbits divided in a similar proportion of male and female were stressed by vehicular transportation and with motion simulation, using a vibration platform. They were divided into five groups: Control (without stress), Stress with Short Transportation (30 min), Stress with Long Transportation (60 min), Stress with Short Vibration Platform (30 min) and Stress with Long Vibration Platform (60 min). Transportation caused a decrease in the haematic potassium in both sexes (<5.2 mmol/L). The glucose and lactate concentrations increased in the transported rabbits (>219 and >61 mg/dl respectively). The differences between sexes showed that the CO in males decreased <8.5 mmHg in stress groups compared to without stress group. Glucose concentration was 61.5 mg/dl for females and 38.0 mg/dl for males (p < .01). We concluded that in rabbits induced stress by transport increased the energetic metabolites in the blood tissue. This increase did not affect the production parameters and the quality of muscle meat.
对兔子应激反应的生前研究较少，且可能影响其血液学反应以及肌肉的理化参数。本研究的目的是在两个不同时间点研究运输和模拟诱导应激反应的情况。将200只按相似雌雄比例分组的兔子，通过车辆运输和使用振动平台进行运动模拟使其产生应激反应。它们被分为五组：对照组（无应激）、短时间运输应激组（30分钟）、长时间运输应激组（60分钟）、短时间振动平台应激组（30分钟）和长时间振动平台应激组（60分钟）。运输导致两性的血钾水平降低（<5.2 mmol/L）。运输后的兔子血糖和乳酸浓度升高（分别>219和>61 mg/dl）。性别差异表明，与无应激组相比，应激组雄性的二氧化碳分压下降<8.5 mmHg。雌性血糖浓度为61.5 mg/dl，雄性为38.0 mg/dl（p <.01）。我们得出结论，运输诱导兔子产生的应激反应会增加血液组织中的能量代谢物。这种增加并不影响生产参数以及肌肉的质量。
