Abstract:
This experiment was conducted to evaluate the effect of replacing inorganic zinc with lower level of organic and nano form of Zn on antioxidant activities and blood biochemical parameters of growing crossbred calves. For this experiment, fifteen crossbred calves were randomly divided into three treatment groups (n=5). These calves were provided with TMR containing 50:50 roughage to concentrate ration as a basal diet along with fixed 2 kg of green fodder. Along with basal diet toppings of different Zn sources were provided to different treatment group animals i.e., ZnSO4 (@ 40 ppm) in T1, Zn-glycinate (@ 20 ppm) in T2 and nano-ZnO (@ 10 ppm) in T3 per kg DM feed offered, for the period of 98 days. Among the groups, no significant (p>0.05) difference was observed in antioxidant activities and blood biochemical parameters except serum albumin level. Serum albumin level was observed to be comparatively higher (p<0.05) in group T3 compared to other two groups. It indicated that supplementation of ZnSO4 (@ 40ppm), Zn-glycinate (@ 20ppm) and nano-ZnO (@ 10 ppm) gave comparable (p>0.05) results among the groups without any adverse effects on growing crossbred calves.
