Aim: The present study was carried out to investigate the relationship between blood serum concentrations of macro and micro minerals and development of retention of placenta (ROP) in crossbred cattle. Materials and Methods: The present study was carried out at Instructional Livestock Farm, Bihar Veterinary College and local Khatals in and around Patna. A total of 20 crossbred cattle (n=10 with normal expulsion of the placenta as control and n=10 with ROP) were selected in the present study. Blood samples were collected from these animals and serum was separated and stored in the deep freezer at −20°C till further analysis. The estimation of serum macro-minerals (Ca, P, Ca/P ratio) was done by Span diagnostic Kits (Surat, India) and trace minerals or micro-minerals (Zn, Cu, and Fe) were analyzed by atomic absorption spectrophotometer (Perkin Elmer AAS 220). Mean values were compared between both the groups at 0 h (at parturition) and 12 h after parturition. Results: The mean values of serum calcium and zinc were found significantly lower in cattle having ROP than control at both 0 h and 12 h after parturition. The mean values of serum Ca and P ratio obtained at 0 hour were significantly lower in ROP groups as compared to control groups and non-significant at 12 h. The mean values of serum inorganic phosphorus, copper and iron was found non-significantly lower in ROP cases as compared to control. Conclusions: Macro and micro mineral deficiency such as calcium, iron, zinc and copper in blood serum may be predisposing factor for the occurrence of retention of placenta in crossbred cattle.
