ABSTRACT
Aim: The study determined the effect of ascorbic acid (administered orally and intramuscularly) in short-term transportation stress.
Materials and Methods: Twenty-four apparently healthy Kalahari goats were grouped into four groups (A, B, C, and D) of 6 animals each: Group A - untreated and unexposed to stress; Group B - treated with 200 mg/kg Vitamin C orally and exposed to 2 h transportation stress; Group C - treated with Vitamin C 200 mg/kg intramuscularly and exposed to 2 h transportation stress; and Group D - untreated and exposed to 2 h transportation stress. The animals were stocked using standards stipulated by the Nigerian Animal Disease Control Act and transported at 40 km/h. Cortisol and interleukin-6 (IL-6) were assayed using quantitative sandwich ELISA. Classical stress hematological parameters and antioxidative stress markers such as glutathione s-transferase, superoxide dismutase, and malondialdehyde were determined. Heart rate variability (HRV) was also assessed.
Results: The route of ascorbic acid administration did not influence the expression of IL-6, and changes in cortisol surge, antioxidative stress markers, and other hematological parameters in Kalahari goats though Group C goats showed higher HRV values (p<0.05) than others. This gives credence to the enhanced cardiac responsiveness and stress survivability in Kalahari goats.
Conclusion: Both routes could be used in the administration of ascorbic acid. Kalahari goats exposed to short-term stress; however, the intramuscular route had better heart variability and thus improved the survivability of the animals.
