Abstract. The paper presents data regarding the impact of some trace mineral supplementation on some pmetabolic parameters of glycine chelated mineral supplemented dairy cows. The study was made on thirty Holstein multiparous dairy cows,  aging arround 62 ± 4.5 months that were divided randomly in two groups: C – Control receiving normal diet without glycine mineral supplementation and one experimental group (E) that received supplement of glycine chelated Cu, Zn, Mn and Fe as follows: 15 mg/kg Cu, 20 mg/kg Mn, 60 mg/kg Zn and, 100 mg/kg Fe, added in concentrate feed. The experiment was designed from day 30 of lactation until day 100 of lactation, and were assesed the potassium (K), phosphorus (P), glucose (Glu), aspartate aminotransferase (AST), alkaline phosphatase (ALP), total proteins (TP), albumin (ALB), urea (U), and creatinine (CRE). In the experimental group we observed significant (p<0.05) decrease of K and P, the non significant decrease of glicaemia and urea and, a significant (p<0,01) decrease of liver parameters such as Ast and ALP in cows supplemented with glycine minerals comparing with controls. There also noted a non significant increase of total pproteins (TP), ALB and CRE in experimental group compared to control. We conclude that supplementing the dairy cows whit chelated minerals could have a benificial role on main biochemical metabolic parameters, being necessary more studies on a long term period.
