The levels of vibration and shock due to transport can affect the quality of fertile eggs. The aim of this study was to characterize and to evaluate the influence of roads on the levels of vibration and shock in the transport of fertile eggs. The survey was conducted in the poultry integrator company in the State of São Paulo, by tracking shipments in three different seasons (spring, summer and autumn). An air-conditioned trunk was used, with a capacity of 592 boxes of eggs, totaling an average of 90,840 eggs. The evaluation of vibration levels (m s-2) and shocks on unpaved and asphalt roads were recorded by four accelerometers brand Hobo. For the vibration level, the experimental design was completely randomized in a 3 x 2 x 4 factorial. For the number of shocks the experimental design was completely randomized with a factorial 3 x 2. The worst levels of vibration and shock load occurred in the vertical direction. The asphalt road provided the worst conditions for the transport of eggs. The transport losses exceeded 1%, which are attributed to cracks and breakage of eggs.
