Summary 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 P CO 2 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.
