Abstract
A study was conducted to evaluate the effect of nanosilver (NS) as feed additive on performance, blood biochemistry and intestinal histomorphology of Vanaraja chicken. Chicks (180 day old) after one week of age were distributed randomly into five treatment groups of four replicates, each having 9 chicks. Treatment groups consisted of T1 (Control) fed basal diet without any additive and in T2, T3, T4 and T5, NS was added to the diet @ 20, 40, 60 and 80 mg/kg diet, respectively. Cumulative body weight gain also improved significantly with the inclusion of NS with highest gain in T5. There was no difference in the feed consumption among various groups including control. Feed conversion ratio was better in T5 compared to other groups. There was no difference in blood biochemical parameters among groups except for the protein levels which were highest in NS supplemented groups than control. The total viable and coliform counts decreased significantly in the group wherein NS was fed in the diet compared to the control. Villus height in different segments of small intestine improved significantly with the inclusion of NS in the diet with better values in T5 followed by T4. From the present study, it could be concluded that nanosilver up to 80 mg/kg level was effective in improving the growth performance, caecal microbiology and intestinal histomorphology of vanaraja birds.
