Online published on 31 August, 2018. Abstract Twenty four male Karan Fries calves of similar age (3–6 month) and body weight (72.85 kg) were divided into 4 groups of 6 animals each to study the influence of different levels of vanadium (V) supplementation on mineral balances and plasma mineral levels. Calves in control group were fed a ration consisting of concentrate mixture, green fodder and wheat straw to meet their nutrient requirements (ICAR, 2013). Calves in treatments T1, T2 and T3 were supplemented with 3, 6 and 9 ppm V (DM basis), respectively. During experimental period of 165 days, blood samples were collected at monthly intervals to study the effect of V supplementation on plasma V, Ca, P, Mg, Fe, Zn and Cu concentration. Seven days metabolic trial was conducted at 7th fortnight of the experimental period to study the effect of V supplementation on retention of V, Ca, P, Mg, Fe, Zn and Cu. Vanadium supplementation improved retention V, Ca, Fe, Cu and Zn (P<0.05) but had no effect on retention of P and Mg. Plasma Ca, P, Mg, Fe, Zn and Cu levels were similar in 4 groups but plasma V level increased in supplemented groups. Hence, supplementation of V upto 9 ppm in the ration increased retention of Ca, V, Fe, Cu, Zn in Karan Fries calves.
