Abstract
The objective of this work was to verify the physical and chemical changes in quail eggs fed with control diet and diets containing percentages of 3.3%, 6.6% and 9.9% of solid fraction of fish residues chemical silage, for 30 days. The experiment was performed using 80 quails of 35 weeks old. They were divided at random into blocks in five cages/diets and four birds/cage. The eggs were selected according to weights varying from 10.5g to 12.0g. For egg composition analysis was used the official methodology, evaluating the moisture, proteins and ashes in yolks and albumens and lipids in yolks.The physical analyses consisted of weight loss, albumen/egg ratio, yolk/egg ratio and shell/egg ratio, specific mass of albumens and yolks, Haugh Units, and yolk index. The data of the present study showed that alterations occurred eggs physical features were rather more correlated with storage time than the change in bird diets. The major egg weight loss was 2.64% at 30th day; and albumen quality decayed from 76 to 72 Haugh Units.No statistically significant differences in quail eggs chemical analyses were observed.References
