“…In addition to its special ESC, the blue-shelled egg is popular in the market for another reason-the absence of trimethylaminuria resulting from the mutation of the flavin-containing monooxygenase 3 gene (Zhang, 2007). Previous studies showed that the Araucana egg has a larger yolk:albumen ratio, lower protein, and higher cholesterol content compared with commercial layers (Somes et al, 1977;Peterson et al, 1978). However, the productivity and egg quality of Dongxiang blue-shelled layers have not been systematically investigated.…”

“…Furthermore, there are other ESC, such as blue. Araucana is a well-known blue-shelled egg layer that has been very well documented (Somes et al, 1977;Peterson et al, 1978). A Chinese indigenous chicken breed named Dongxiang, which originated from Jiangxi Province, also lays blue-shelled eggs and has been used for commercial egg production recently.…”

Blue-shelled eggs are gaining popularity as the consumption demand diversifies in some countries. This study was carried out to investigate the laying performance and egg quality of the blue-shelled egg layers as well as the effects of different housing systems on egg production and quality traits. One thousand pullets from Dongxiang blue-shelled layers were divided into 2 even groups and kept in different housing systems (outdoor vs. cage). Daily laying performance was recorded from 20 to 60 wk of age. External and internal egg quality traits were examined at 26, 34, 42, and 50 wk. Yolk cholesterol concentration and whole egg cholesterol content were measured at 40 wk of age. Average laying rate from 20 to 60 wk for the cage (54.7%) was significantly higher than that of outdoor layers (39.3%). Among all of the egg quality traits, only eggshell color was affected by housing system. Interaction between housing system and layer age was found in egg weight, eggshell color, eggshell ratio, yolk color, and yolk weight. Meanwhile, cholesterol concentration in yolk was 8.64 +/- 0.40 mg/g in the outdoor eggs, which was significantly lower than that of eggs from the cage birds (10.32 +/- 0.48 mg/g; P < 0.05). Whole egg cholesterol content in the outdoor eggs (125.23 +/- 6.32 mg/egg) was also significantly lower than that of eggs from the caged layers (158.01 +/- 8.62 mg/egg). The results demonstrated that blue-shelled layers have lower productivity in the outdoor system than in the cage system. Blue-shelled layers have lower egg weight, larger yolk proportion, and lower cholesterol content compared with commercial layers. In a proper marketing system, lower productivity could be balanced by a higher price for the better quality of blue-shelled eggs.

“…As Somes et al (14)'s report it is probably the reason that Araucana had the highest yolk cholesterol might possibly be due to its lower egg production. It is also possible that layer straim have lower yolk cholesterol content because of the negative correlation between yolk cholesterol and egg production.…”

“…Comparative investigations on the quality traits of eggs and their cholesterol content have been performed during the second half of the 20 th century with the breed Araucana and commercial hybrids (13,14). Sadjadi et al (15) investigated the production traits and egg quality produced by F2 crosses between Araucana and Shaver Starcross "288", and found out lower egg production in crosses laying white eggs compared to those laying blue-green eggs, but no changes in egg quality.…”

During the past decade, consumers in some regions of the world evidenced a marked interest to eggs with non-traditional shell colour. The aim of the present study was to investigate the productive traits of Easter eggers, obtained by crossbreeding of Araucana and Schijndelaar roosters with White Leghorn layer hens. For this purpose, a total of five groups of hens were used: three control: group L (White Leghorn), group A (Araucana), group S (Schijndelaar) and two experimental: group AWL (F1 Araucana×White Leghorn) and group SWL (F1 Schijndelaar×White Leghorn). During the production cycle which continued up to 65 weeks of age, the following traits were evaluated: live weight at 20% and 50% egg production; economic maturity; average weekly feed intake and feed conversion, egg production and egg weight. At the age of 50% egg production, Araucana had the highest live body weight (1408.25 ±19.25 g), and Leghorns -the lowest (1297.45 ±10.25 g) (p<0.05). The best economic maturity was exhibited by White Leghorn group (135 days of age), whereas the Schijndelaar group attained economic maturity at 205 days of age. The most efficient feed conversion (p<0.001) for production of one egg and 1 kg egg mass was observed in group L (133.46±1.94 g and 2.19±0.05 kg/kg respectively). The highest hen-day egg production was recorded in group L and the lowest -in Schijndelaar (group S) and Araucana (group A). The weight of White Leghorn eggs was substantially higher (р<0.001) compared to eggs laid by Schijndelaars and Araucanas. The traits characterizing the economic efficiency of layer hens (feed conversion per egg produced and per 1 kg egg mass) in experimental groups were comparable to traits recorded in heavy egg-laying hybrids.
