Abstract:
This study included two consecutive experiments, the first experiment was conducted in the hatchery of Al-Anwar company in Babylon province for the period from 30/7/2017 to 19/8/2017 in order to investigate the effect of injecting hatching eggs to broiler breeder with different levels of nano-silver, and then examining its subsequent effect on traits. The physiology of the hatched chicks subjected to heat stress, as the experimental treatments were the treatment T1 without injection as a negative control, and the treatment T2 was an injection of 0.3 ml of Nacl solution as a positive control, and the treatments T3, T4, T5 and T6 were injections of hatching eggs with 12,14,16, 18 ppm of a nano-silver solution, respectively. The hatched chicks from the above treatments were reared in the poultry farm of the Department of Animal Production at the College of Agriculture / Al-Qasim Green University for the period from 8/19/2017 to 9/22/2017, and were exposed to a periodic temperature. (28-32-28 m ⸰) and the results showed a significant (P≤0.05) superiority of the injection treatment T6, T4 in the number of red blood cells compared with the rest of the treatments and the superiority of the treatment T4 in the number of white blood cells compared with the rest of the treatments at the age of three weeks, while In the fifth week, the two treatments T5 and T6 excelled in the number of red blood cells and Treatment T6 leukocytes compared with the rest of the treatments. It was found that there was a significant superiority (P≤0.05) for treatment T4 in the concentration of cholesterol and ALT enzyme, while treatments T4, T5 excelled in glucose concentration, and treatments T1, T6 had the highest concentration of AST enzyme compared with the rest of the treatments.
