Abstract :

   Nanosilver, as nano-particles of silver, is one of the most widely used in the field of nano- technology. The particles cause widespread use of poultry houses due to their antimicrobial properties. Application of excess material in poultry houses lead to the residual of silver in muscle, liver and kidney in broiler chickens after a period of administration that it should be evaluated. In this study, 270 one-day old broiler chickens (Ross strain) were selected. The nanosilver that used in this study (nonacid) was manufactured by Chemical Bahaman Iran Co. The Concentration of nanocid was between 1 to 7 ppm. A week after end of nanosilver administration, chickens were slaughtered and liver, kidney and breast muscles (total of 36 samples for each limb) were obtained. The data was analyzed by SAS statistical program and Duncan test. Total mean residual of silver in different organs were 1.5 (ppm). The residual silver of the experimental group were significantly higher than those of the control group (P<0.01). There were no significant differences between residual amount of silver in the liver and muscles, but there was significant difference between kidney and other tissues. Results indicated that the amount of silver residue in the different organ was depended to the level of nanosilver consumption. These results seem to support the hypothesis that application of nanosilver must be with precaution.
