“…The background colour of the eggshell varies from white to light tan and light brown. In quail eggs, the colour of the spots can be blue, black, or brown (Narahari et al, 1988). While the blue-green coloured biliverdin is an antioxidant eggshell pigment, the brown coloured protoporphyrin is a pro-oxidative eggshell pigment (Moreno and Osorno, 2003).…”

The impact of eggshell colour and spot area in Japanese quails: II. Slaughter and carcass characteristic

et al. 2016

-This study was carried out to investigate the effects of eggshell colour and spot properties (colour and size of the spot area) on growth performance and carcass traits of Japanese quail (Coturnix coturnix japonica) eggs. Study material were allocated to five groups according to their eggshell and spot colours: black spots on greyish white coloured eggshell (I), blue spots on greyish white coloured eggshell (II), diffuse brown spots on greyish brown coloured eggshell (III), brown spots on light green colored eggshell (IV), and small brown spots on greyish brown coloured eggshell (V). The size of the spotted area was determined in each egg group using digital image analysis. The groups did not differ for body weight and length of the shank at the end of the growth period. However, the groups differed significantly for carcass yield after slaughter (not eviscerated) and carcass yield. These parameters were highest in Group I (82.08 and 76.09%) and lowest in Group III (80.20 and 73.86%). Digital image analysis demonstrated that heart length, cardiac fat area, gizzard width, and intestine length varied between the groups. Cardiac fat area was largest in Group III (0.86 cm 2 ) and smallest in Group V (0.65 cm 2 ). Gizzard width was greatest in Group I (2.63 cm) and smallest in Group V (2.47 cm). Intestine length was greatest in Group V (78.45 cm) and smallest in Group IV (72.39 cm). Body weight, shank length, and slaughter and carcass weight do not vary in relation to eggshell colour or the size of the spotted area. The lengths of intestine and heart, gizzard width, and cardiac fat area do vary in relation to eggshell colour or the size of the spotted area.

“…For eggs stored for less than 4 d, egg room temperature should be 20-25°C, whereas for those stored 4-7 d, temperature should be maintained between 16 and 17°C, and for eggs stored for more than 7 d, temperature should be lowered to 10-12°C (Meijerhof, 1992). Narahari et al (1988) stored the hatching eggs of Japanese quails for a period of 1-7 d and determined that the highest rates of fertility and hatchability of fertile eggs were obtained in the eggs stored for 1-3 d. Similar results were obtained by Petek et al (2003), who recommended that the storage period of eggs of quail should be no longer than 3 d. However, Romao et al (2008) reported that quail eggs present great hatchability until 10 d of storage and that eggs offered to storage present a reduced weight loss during incubation. Different studies showed that hatchability of eggs decreases quickly after 8 d of storage period for pheasant (Demirel and Kırıkçı, 2009), 7 d of storage time for duck (Onba ılar et al, 2007), 5 d of storage time for broiler breeder hen (Petek and Dikmen, 2006) , 28 d of storage length for partridge (González-Redondo, 2010), 15 d of storage length for ostrich (Hassan et al, 2005) and 4 d of storage length for guinea fowl eggs (Moreki and Ditshupo, 2012).…”

In this study, hatchability characteristics and some internal egg quality characteristics of 0, 2, 3, 4, 6 and 8 d stored Fayoumi eggs were examined. It was determined that the effect of storage time on hatchability, hatchability of fertile eggs, embryonic mortality, hatchling weight, albumen weight, yolk weight, albumen index, yolk index and Haugh unit was significant (P<0.05). There was no positive or negative effect of storage time on the fertility rates, but there was a negative effect of storage time on egg weight, hatchability, embryonic development and hatchling weight on d 4 (P<0.05). It was determined that prolonged storage time caused a decrease in the albumen weight, yolk weight, albumen index, yolk index and Haugh unit value of Fayoumi eggs. Fayoumi eggs should not be stored more than 3 d.
