dc.description.abstract | This study aimed to evaluate and compare the bacteriological and physical
quality of eggs marketed in the city of Santa Maria/Rio Grande do Sul, from hens raised
cage-free and in conventional system, in order to verify whether these eggs have
similar microbiological and physical quality, for this purpose 360 eggs were purchased,
180 eggs from cage-free hens and 180 eggs from hens raised in cages, these eggs
were subjected to analysis of Salmonella spp., total and thermotolerant coliform
analysis, Haugh unit, yolk index, yolk color, egg weight and shell thickness, after which
the results were subjected to statistical analysis to assess whether there was
significant difference (p ≤ 0.05) between the two groups analyzed and as results we
obtained difference in relation to egg weight (55,58 g conventional and 62.75 g cagefree) and dry shell (6.01 and 6.39 g), color (5.83 and 11.14), height (2.99 and 3.47 mm)
and yolk width (42.54 and 43.56 mm), albumen height (2.99 and 3.47 mm) and yolk
index (0.282 and 0.296) and in relation to microbiological analyses we obtained
13.33% presence of Salmonella spp. in eggs from conventional breeding, against
6.66% of cage-free eggs and in the quantification of coliforms in conventional eggs we
obtained 152.86 MPN of total coliforms and 80.14 of thermotolerant coliforms, and in
cage-free eggs 0.44 MPN of total coliforms and 0 MPN of thermotolerant coliforms,
showing a lower bacterial contamination and better physical quality of eggs from cagefree birds and marketed in the city. | |
