“…Similarly, Torma and Kovácsné (2012) proved that when hatching eggs are vibrated in an intense treatment (30 Hz; 10 min), they present a Torma and Kovácsné (2012) hypothesis, which is raised in this research, may be supported in Berardinelli et al (2003aBerardinelli et al ( , 2003b works. These authors verified that exposure of eggs to vibration effects turns the albumen's denser portion (intermediate) more liquid, which is confirmed by a significant reduction of up to 28% in Haugh units' average values.…”

“…These authors verified that exposure of eggs to vibration effects turns the albumen's denser portion (intermediate) more liquid, which is confirmed by a significant reduction of up to 28% in Haugh units' average values. The albumen's liquefaction process is related to eggs' quality reduction and premature aging (Berardinelli et al, 2003a(Berardinelli et al, , 2003b.…”

“…The results were related to the cracks in eggshells, liquefaction of albumen with reduction in the values of Haugh unit and the lower resistance of the yolk's membrane, clearly demonstrating the negative effects of vibrations on the internal quality of eggs (Berardinelli et al, 2003a(Berardinelli et al, , 2003b. But, what would happen with hatching eggs get exposed to vibrations?…”

“…The main consequences of this agent are related to stress and a drop in quality of broilers' meat transported for slaughter (Randall et al, 1993;Randall et al, 1997;Carlisle et al, 1998;Abeyesinghe et al, 2001), in addition to the loss of eggs for human consumption and/or hatching, as a result of cracks, breaks and changes in internal quality (Berardinelli et al, 2003a(Berardinelli et al, , 2003bTorma and Kovácsné, 2012;Nazareno et al, 2013).…”

Many factors present in eggs' transportation from incubator to growing confinements can damage their integrity and, consequently, the results of the incubation. This study aimed to evaluate whether the intensity and duration of exposures of hatching eggs to mechanical vibrations were capable of affecting the hatch and the quality of broiler chicks. Four treatments, determined by two intensities of vibrations and two durations of exposures were evaluated and compared with a control group in a randomised design in blocks with four repetitions. The vibrations were applied by a mechanical shaker before incubation. Then the eggs were incubated and as the following responses were evaluated: hatchability, the type of embryonic mortality, the quality of the birds and the total of losses. The analyses were carried out by a binomial regression model, with application of the Wald test at 5% significance level. The results showed that the exposure of eggs to mechanical vibrations harmfully affects the hatchability and reduces the ratio (percentage) of high quality chicks. Highest vibration level together with longer duration of exposure resulted in worst hatchability and losses. It is argued that the mechanical vibrations are potentially damaging and should be regarded as an important factor in the management of hatching eggs.

“…Furthermore, literature presents several contributions on the damage caused by static and dynamic mechanical stresses on selected foods such as fruits and vegetables (Singh and Singh, 1992) and eggs (Berardinelli et al, 2003a). These damages are influenced by the following factors: the type of packaging (Singh and Xu, 1993), the mechanical properties of food products (Berardinelli et al, 2006), the type of transport vehicles and the position of products inside the vehicle (Barchi et al, 2002), and finally the conditions of the ''road surface'' (Berardinelli et al, 2003b).…”
