Foram utilizadas 64 fêmeas com peso médio de 133+11kg, oriundas de duas granjas de terminação. Os tempos de jejum avaliados foram nove, 12, 15 e 18h, enquanto que as posições consideradas na carroceria foram box (frente, meio e atrás), piso (inferior e superior) e lado (lateral direita e esquerda). Ao abate, foram medidos os níveis de glicose, lactato e CPK no sangue. A concentração de cortisol na saliva (CCS) foi medida nas granjas (24 horas antes e após embarque) e no abatedouro (logo após o descarregamento e antes do abate). A freqüência cardíaca foi monitorada durante todo o manejo pré-abate. Foi observado o efeito da interação entre TJG e o local de avaliação sobre a CCS e a freqüência cardíaca. A CCS e a freqüência cardíaca aumentaram significativamente da granja ao desembarque no abatedouro em relação ao descanso pré-abate no abatedouro foi observada uma redução (P0,05) os níveis de glicose, lactato e CPK no abate dos suínos. The aim of this study was to evaluate the effect of fasting time on the farm (TJG) and the position of the animals on truck compartment during transport to slaughterhouse in the hormonal and physiological status of heavy-weight swine in order to obtain future management improvements and to reduce meat quality downgrades. Sixty-four females obtained from two farms and averaging 133+11kg body weight were used. Fasting time evaluated on farms were 9, 12, 15 and 18 h while the positions considered in the truck were Box (front, middle, and back), Deck (under and upper level) e Side (right and left). Swine blood concentration of glucose, lactate and CPK were evaluated at slaughter. Cortisol concentration on saliva (CCS) was evaluated on the farm (24 hours before uploading and after loading) and at slaughterhouse (after downloading and before slaughter). Hearth frequency was continuously evaluated during pre-slaughter management. Interaction between TJG and moment of salivary cortisol sampling and heart rate data recording were observed. CCS and heart rate values increased from farm to truck downloading at slaughterhouse, while pre-slaughter resting reduced (P0.05) on glucose, lactate and CPK levels at slaughter time.
