The experiment was conducted on 18 Wistar rats during a six-week period; 12 animals were given zinc lactate (120 mg/rat and week) in feed mixture and 6 control animals were fed a standard mixture for rats (ST-1). Sixteen biochemical parameters were measured from blood (serum) samples: total protein (TP), albumin (ALB), urea (UREA), glucose (GLU), triacylglycerols (TAG), non-esterified fatty acids (NEFA), cholesterol (CHOL), creatinine (CREAT), alkaline phosphatase (ALP), aspartate aminotransferase (AST), uric acid (UA), magnesium (Mg), calcium (Ca), phosphorus (P), and trace elements such as Fe and Zn. When compared to the control group, we found that rats fed zinc lactate had higher concentrations of GLU, UA, UREA, Fe, Mg, Ca, TAG, TP, ALB, and ALP in the blood serum. Contrarily, the concentrations of AST, NEFA, CHOL, CREAT, P, and Zn were higher in the blood serum of control rats. Statistically significant differences between rats fed Zn and the control were found only in the concentrations of GLU, AST, ALP, UA, and P.
