The present study was conducted to elucidate the plasma mineral profile and serum biochemical parameters in Holstein Friesian cross bred cattle in different physiological stages and seasons. In each season and each physiological group 8 normal healthy animals randomly selected for blood sampling once in a month for minerals Ca, P, Cu, Zn and Mn; biochemical parameters glucose, BUN, and NEFA analysis. | Effects of physiological status and season on blood biochemical and mineral profile of Holstein Friesian cross bred cattle
