Qualidade de ovos férteis sob diferentes períodos de armazenamento

Abstract

The objective of this work is to evaluate the quality of fertile eggs under different storage periods. The experiment was conducted at home due to the COVID19 pandemic. One hundred and fifty eggs of heavy breeders, cobb 500 lineage, 39 weeks old, with egg weight from 60 to 65 grams, were used. Eggs were randomly distributed to 7 treatments, being T1: day 0 (control treatment), T2: 7 days at room temperature (TA), T3: 7 days at refrigerated temperature (TR), T4: 14 days at room temperature (TA), T5 : 14 days at refrigerated temperature (TR), T6: 21 days at room temperature (TA), T7: 21 days at refrigerated temperature (TR). Egg weights, shell percentage, shell thickness, shell percentage, albumen height, Haugh Unit, yolk weight, albumen index, yolk index, yolk diameter, albumen weight, albumen diameter, were evaluated yolk color, yolk percentage, white percentage. It was observed that egg weight and shell percentage were not affected by any of the treatments. Eggs submitted to room temperature had worse internal quality results when compared to eggs submitted to a refrigerated environment.
