The higher level (9 mg/kg) significantly reduced serum GPT and GOT activities, suggesting better hepatic function and less hepatocellular damage, although only minor changes were observed in GSH and MDA values. Zinc-supplemented rabbits showed decreased blood glucose concentrations, consistent with enhanced insulin sensitivity and more efficient carbohydrate metabolism. In contrast, the higher zinc dose was associated with slight elevations in serum cholesterol and urea, which may reflect an emerging metabolic imbalance. </span></span></span></span></span></span><br> <span style="font-size:11pt"><span style="line-height:150%"><span style="font-family:Calibri,sans-serif"><b><span style="font-size:12.0pt"><span style="line-height:150%"><span new="" roman="" style="font-family:" times="">Conclusion</span></span></span></b><span style="font-size:12.0pt"><span style="line-height:150%"><span new="" roman="" style="font-family:" times="">: Overall, moderate dietary zinc supplementation appears to support liver function and metabolic health in adult male rabbits while maximising physiological benefits and minimising potential adverse effects.</span></span></span></span></span></span> Dietary zinc supplementation,liver enzymes,antioxidant status,blood metabolites,serum proteins,hepatic function. 371 376 http://ijwph.daneshafarand.org/browse.php?a_code=A-10-1-81&slc_lang=en&sid=3 Baydaa Abed Hussein Baydaaabd@uomanara.edu.iq 1003194753284600380217 1003194753284600380217 Yes
