The impact of flucycloxuron on eggs weight kinetic and hematological parameters of chicken (Gallus domesticus).

The struggle against the harmful bugs of culture is intensified, and several products are appeared every year without the knowledge how to control their effects on environment and especially on being life. The introduced chemical products in nature are generally, the synthesis products witch are the pesticides. Our study consist the impact mechanism of a pesticides (FCX) on other biological model than harmful bugs, this biological model is a vertebrate model witch is the domestic chicken eggs (Gaollus domesticus). The toxicity of Flucycloxuron reviewed across the eggs weight kinetic accompanied with embryonic hematological parameters, in ovo and after hatching. The tested concentrations of pesticide are 1, 10 and 20 microg/egg injected at first day of incubation. Eggs treatment by three concentrations of pesticides, disturbs the studied parameters, where we observe that the pesticide inhibit the nutriment transformation, translated by eggs decreased weight kinetic according to the control, also the FCX affect the shell weight and cause the alteration of shell integrity. Hematological parameters show a clear impact of the pesticide at the lowest concentration (1 microg/egg). The obtained results confirm that the chosen biological model is good bio-indicator for eventual pollution and they are not far from pesticides toxicity.
