Abstract: The influence of age (85, 140, and 270 days) of European quails breeders on the egg quality and hatching, fertility and progeny performance was evaluated. The experimental design was completely randomized in a 3x3 factorial arrangement (females' age x males' age), with ten replicates and six birds per experimental unit (four females and two males). Egg production and quality were determined during 3 periods of 14 days and incubation parameters were evaluated in eggs obtained in five consecutive days. The live … Show more

“…The results regarding the hatching:fertile egg ratio corroborate those of Santos et al (2015), who studied quail breeders of different ages and also found that older quails (48 weeks) had worse results for egg hatching than those of younger breeders (20 weeks old) and corroborate those of Araújo et al (2016), who studied broiler breeders of different ages and also found that older quails (59 weeks) had worse results for egg hatching than those of younger breeders (29 or 35 weeks). According to Almeida et al (2006), the lower rate of egg hatching among older breeders can be explained by the poorer quality of the shell, which results in a high rate of embryo mortality.…”

“…The highest degree of correlation (p <0.05) of the parameters of quail eggshell quality analysis occurred between breaking strength and shell percentage (Table 3), probably, because the percentage of shell in quail eggs is one of the lowest as compared with eggs of other poultry species (TOLIK et al, 2014). In spite of that, quail eggs present increased membrane thickness in relation to the total shell volume, and according to Santos et al (2015), they are extremely elastic and resistant structures, which confer greater resistance to egg breaking in this species.…”

“…Another issue to be considered for the understanding of those results concerns the structural conditions hen and quail eggshells in relation to the organic matter content, which according to Pereira et al (2009) is higher in hen eggshells, in addition in both species the calcium content in the shell is around 37% of the mass of this structure. In addition, the shell of quail eggs is thinner (SHANAWAY, 1994), but the thickness of the shell membranes in relation to the total shell volume is greater as compared with that of hen eggs, accounting for 21% of the total shell thickness, while in hen eggs, they represent 11% (BARBOSA et al, 2012;SANTOS et al, 2015). Thus, based on these results, the analysis of specific gravity by the methodology used in the present study may not be adequate for measuring the shell quality in eggs of this species, assuming the need to make saline solutions with densities different from those used for hen eggs.…”

“…A camada paliçada compreende, aproximadamente, dois terços da espessura total da casca, portanto quanto maior a sua espessura, maior será a espessura total da casca e sua resistência (Radwan et al, 2010). A espessura da camada mamilar também confere característica de resistência à casca (Hunton, 1995) e, apesar de representar menos de um terço da composição total da casca, essa é a camada responsável pelo início dos processos de quebra dos ovos (Bain, 1992 Barbosa et al, 2012;Santos et al, 2015).…”
