Abstract
Endocrine disrupting chemicals have harmful effects on the reproductive performance in birds. Hence, the target of this study was to inspect the reproductive and physiological changes attributable to in ovo and pre-pubertal injection of Japanese quail to Bisphenol A, as one of EDCs. In two experiments, the first, 400 quail fertile eggs were in-ovo injected with BPA. In the second experiment: 80 Three-week-old quails were injected intra-peritoneal with BPA for three consecutive weeks. Results revealed that the consequence of exposure to environmental endocrine disruptors pollutant, such as estrogenic-like BPA before/at puberty makes malformation and malfunction of reproductive tissues gonads causing decreases of reproductive capacity that seems not to be regenerated in adult quail.
Key words: Endocrine disrupting chemicals, Bisphenol A, in ovo injection, intraperitoneal injection, productive, reproductive, Japanese quail.
