In ovo injection of silver nano particles, thyme and savory extract on growth performance and blood parameters in broiler chicks

This experiment was conducted to examine the effects of in ovo injection of thyme and savory extracts as organic and nano silver inorganic matters. A total of 891 fertilized eggs were used under completely randomized design (CRD) with 11 treatments by 3 replications and 27 eggs in each. Treatments including: 1(control no injection); 2(control 1cc physiologic serum; 3 (30ppm nanosilver); 4 (45ppm nanosilver); 5 (60ppm nanosilver); 6(100ppm thyme); 7(150ppm thyme); 8(175ppm thyme); 9(100ppm savory); 10(150ppm savory); 11(150ppm savory). On the 17th days on incubation the eggs were candled then injected in air sac. Cholesterol and glucose levels of 150 mg of savory were significantly increased at 14 day of age and the level of glucose affected by savory and thyme levels at 21 of age (p<0.05). Results of this research have shown that effects of in ovo injection of thyme and savory extracts have been better than nano silver, in measured parameters.
