Effects of Feed Type With/Without Nanosil on Cumulative Performance, Relative Organ Weight and Some Blood Parameters of Broilers

摘要

In a 2 × 2 factorial design, the effect of Nanosil [ionic silver and H2O2] in broiler diet on cumulativeperformance, relative organs weight [liver, spleen and bursa of fabricius] and blood uric acid, serumglutamate–oxaloacetate transaminase (SGOT) and serum-glutamic pyrovic transaminase (SGPT) wereinvestigated. The first factor was feed type (mash or pellet) and the second was Nanosil (with or without).Main effect of feed type on weight gain was significant (p 0.05). Main effects of Nanosil on weight gain, indays of 1-35 and 1-42, were significant (p 0.05). Interaction effects of feed type and Nanosil on feed intak, indays of 1-7 and 1-42, were significant (p 0.05). Main effects of feed type on feed intak, in days of 1-14 and 1-35,were significant (p 0.05). Interaction effect of feed type and Nanosil on feed conversion ratio in total period(days of 1-42), was significant (p 0.05). Main effects of feed type on feed conversion ratio, in days of 1-7, 1-14,1-35 and 1-42, were significant (p 0.05). Interaction effects of feed type and Nanosil on relative weights of liver,spleen and bursa of fabricius were significant (p 0.05). Treatments had no effects on SGOT and SGPT activity.Main effect of Nanosil on blood uric acid was significan (p 0.05). Based on the results of this investigation,pellet had suitable effects on broiler performance and it seems that Nanosil in this case had negative effects onrelative organ weight and blood uric acid and may be used in lower concentration in the broiler’s diet.
