The Effect of Silver Nanoparticles, Thyme and Savoury Extracts Injection to Egg on the hatchability, digestive and Immunity Parameters at Hatchability

An experiment was conducted with 855 fertilized eggs in 8 treatments (injection in 5th day of incubation) and 11 treatments (injection in 17th day of incubation) with 3 replicates of 15 eggs each. Treatments included first control (no injection)، second control (injection of 0. 5 ml. of sodium chloride); in 5th day، experimental treatments included 30 and 45 mg. silver nanoparticles، and 100 mg. of thyme and savoury. In 17th day treatments included 30، 45، and 60 mg. silver nanoparticles، and 100، 150، and 175 mg. of thyme and savoury extracts. Injection in 5th day indicated that the bursa weight reached its maximum in treatments 75 and 100 mg. of thyme، and 75 mg. of savoury، and in treatments with 30 and 45 mg. of silver nanoparticles had a minimum level (P).
