摘要:Background and Objective: Gamma aminobutyric acid (GABA) can relieve stress intensityand ascorbic acid can protect against weight loss. Together, these agents can minimize weight loss and stress during cattle transportation. The objective of this study was to evaluate the effects of ascorbic acid and GABA on the physiology of Bali cattle during transportation. Materials and Methods: The study was designed using a completely randomized design of factorial patterns. The first factor was ascorbic acid (0 mg kg1 body weight (bw) and 100 mg kg1 bw dosage) and the second factor was GABA (0, 0.6, 1.2 and 1.8 g head1 dosage). Statistical calculations were performed to determine differences between treatments using Duncan’s multiplerange tests. Results: Ascorbic acid (100 mg kg1 bb) and GABA (1.2 g tail1) reduced cortisol levels and weight loss (p0.05). Conclusion: Administration of ascorbic acid and GABA (100 mg kg1 bw and 1.2 g tail1, respectively) reduced blood cortisol levels and protected against body weight loss. Coadministration did not have a significant effect on rectal temperature, respiration, or heart rate .
