Effects of Turmeric and Rosemary Extract on Oxidative Stress Markers in Goats

Background: Due to their versatility, goats are becoming popular as livestock on commercial farms. To obtain a high productivity, the maintenance of homeostasis in these organisms is needed. Some supplements that could help improve their health state have been tested recently. The study examines the effects of a turmeric-rosemary extract mixture on the antioxidant status of the blood of young castrated bucks. Results: Supplementation lowered lipoperoxidation and increased TAC, probably due to the improved neutralization of reactive oxygen species (ROS) by enhanced antioxidant pathways. Despite lowering lipid peroxidation, these products can increase protein oxidation. Thus, while enhancing lipid defense mechanisms may reduce lipid peroxidation, it may also increase the level of OMP, probably due to the accumulation of lipid peroxidation metabolites. The activities of SOD, GPx, and GR remained unchanged, whereas CAT activity decreased. CP, ALT, and AST remained stable, suggesting no adverse effects on key markers of liver function. Conclusions: The high antioxidant potential observed after supplementation indicates that the turmeric-rosemary extract mixture elicited a favorable biochemical response; the supplemented compounds effectively enhanced antioxidant defenses (by improving the neutralization of ROS) without negatively affecting liver enzyme activities. Turmeric-rosemary dry extract supplementation can help with homeostasis maintenance in goat organisms and, consequently, improve their productivity.
