The present study was undertaken to evaluate the influence of supplementation of chelated mineral mixture on growing buffalo calves in the field through front line demonstration. Sixteen buffalo calves were divided into two equal groups viz., Group T1 (Control) and T2 (treatment). Group T1 received roughages and concentrate mixture prepared as per the practice of farm and group T2 received same ration as per group T1 and supplemented with chelated mineral mixture @ 25g/day. The results of the study revealed that on or after 120 days of supplementation in T2 group there was significantly higher (P<0.05) bodyweight gain, DMI, FCE, Body measurements, as compared to control T1 group, while average mean of feeding cost did not differ significantly (P<0.05) in calves of both the groups so the present study was finally concluded that feeding of chelated minerals has beneficial effect on growing calves.
