Avaliação dos parâmetros de análises físicas de ovos nos modelos de produção: cage free e tradicionais

Abstract

The study's theme was the evaluation of physical analysis parameters in eggs from different production models. The following guiding question was used to outline the study: What are the main parameters that define the macroscopic quality of eggs and their relationship with the breeding system to which the birds are subjected? Given this, the methodology used was quantitative research with a descriptive approach. The general objective was to verify the physical characteristics of the eggs and compare the results between the breeding models. To this end, the following specific objectives were used: to analyze the systems for raising laying hens; to compare the types of systems, namely: conventional and alternative (cage-free); to analyze the quality parameters of the eggs among their aspects of evaluation of egg weight, shell resistance, albumen height, haught unit and yolk color; to specify the importance of quality tests. It is concluded that, given the average of the data verified by the following parameters: egg weight, albumen height, yolk color, Haugh unit and shell resistance, the Cage Free system stood out for presenting the most satisfactory values in all the parameters analyzed, values that can be attributed to better well-being of the birds compared to the others.
