Abstract

To examine the possible role of maternal effect on progeny immune system development, the injection effects of the Khazak yolk into the yolk of the commercial Ross egg on the performance, immunity and expression of TLR4 was determined in a commercial Ross chicken. For this purpose, 150 Ross fertile eggs were randomly assigned to two experimental groups including group I (control in-ovo Ross yolk injection) and group II (in-ovo Khazak yolk injection) and were kept in incubator for three weeks. After incubation period, newly hatched chickens were fed with balanced ration for six weeks. Three chickens from each experimental group were killed at 27-and 42-d post hatch for analysis of immune organs weight (liver, burs and thymus), the HI anti-body titer levels and liver TLR4 mRNA expression levels. The results of statistical analysis demonstrated that the in-ovo injection of Khazak yolk into the Ross eggs not only significantly enhances growth rate and immune function but also decreases expression of TLR4 mRNA in the liver of treated group compared with the control group (p˂ 0. 05). Based on these results, it's possible that injection of Khazak yolk into the Ross eggs at the first day of embryonic development enhances the chicken immune response at older ages.
