Influence of Graded Levels of Different Sources of Zinc on Growth Performances and Production Economics in Chicken

Siddhartha Shankar Pathak, Asish Saikia, Uma Ram Tamuli.


An experiment was undertaken to evaluate the growth parameters and economic benefits of nano-zinc feeding compared to inorganic and organic sources of zinc. A total of 336 day old Giriraja chicks were allotted in seven treatments with four replicates in each group having 12 chicks in each replicate (48 chicks per treatment) in Completely Randomized Design. Dietary treatments consisted of Zinc sulphate and Zinc methionine at (30 and 60 ppm) respectively; while 15, 30 and 60 ppm for nano- zinc. Body weights (g), feed consumption and FCR were recorded weekly. During all the weeks, body weight and FCR were higher with comparatively higher feed consumption and higher return for nanozinc at 60 ppm level suggesting increase profitability. The profit on the basis of FCR was highest (Rs 68.41) for zinc sulphate at 30 ppm with lowest profit (Rs 66.35) for nano-zinc at 60 ppm.
