The objective of this work was evaluate the possible changes in the chemical and physical characteristics of quail eggs fed with diets containing fish oil and solid fraction of fish chemical silage, along 30 days. The experiment was conducted using 80 quails 19 weeks old, distributed in a total occasional design with 4 treatments, 5 repetitions and 4 birds by experimental unit. The physical analyses were: Haugh Unit, yolk index, volumes of albumens and yolks and relationship of albumen/egg, yolk/egg and shell/egg. For the chemical analyses was used official methodology, specific for eggs. In this work was verified, in the end of the analysed time, a weigth loss of 3,43%; a decrease in the albumen quality, the Haugh Unit lowered from 67 to 64 and a rise of 5% in the humidity percentual of the yolks. Also was observed that the albumen volume is stabler than of the yolks and that the albumen proteins are instable front to its basic pH.
