“…Our results shown in Table 10 revealed that there were significant increase in albumin weight and albumin percent in battery cage than floor pen reared quail. These results are in agreement with (Sari et al 2012) and Mirjana et al (2012). Shell Thickness, weight and percentage: The most important quality traits of the egg shell are its thickness.…”

This study was conducted to investigate the effect of two different housing systems; floor pens vs. battery cages on productive traits in Japanese quail. Three hundred, one day old chicks were individually weighed and randomly divided into two equal experimental groups according to housing system (150 birds in each group), each group was randomly assigned to three replicates. Body weight, body weight gain, feed consumption, feed conversion ratio and mortality rates were recorded weekly during the first experimental period. At the end of the growing period slaughter test was carried out to estimate carcass quality characteristics. Feed intake , feed conversion ratio and mortality rates were recorded. The dressed carcass, heart, liver, head and gizzard were weighed. The pooled weight of heart, liver, gizzard, and edible meat were designated as total edible meat (TEM). Using floor pens improved Gizzard weight, and gizzard percentage values compared to battery cages. Egg production, and egg quality traits, were estimated during the second experimental period. It was concluded that housing system had no significant effect on productive most traits of Japanese quails. Using floor pens improved gizzard weight, gizzard percentage, egg yolk weight and egg yolk percentage values of floor pen reared quails compared to battery cages. It was concluded that housing system had no significant effect on most of productive traits of Japanese quail

This study was carried out to investigate selected traits of hatched and unhatched eggs and chick growth performance of yellow Japanese quails (Coturnix japonica). Eggshell temperature at the time of transfer to the hatcher was higher in hatched eggs (38.09 o C) than in unhatched eggs (37.43 o C) (p=0.000), lower in eggs with in early embryonic mortality (37.39 o C) than those with late embryonic mortality (38.13 o C) (p=0.000), and higher in eggs with female chicks (38.14 o C) than those with male chicks (37.95 o C). Lower eggshell, yolk, and albumen weights were determined in eggs with embryonic mortality of 17-18 days (0.58 g, 3.13 g and 4.96 g) compared with those with 10-16 days (0.67 g, 3.55 g and 5.58 g) and embryonic mortality of 1-9 days (0.75 g, 3.95 g and 6.19 g) (p=0.000). Lower egg weight loss was obtained in eggs with embryonic mortality (13.85%) of 1-9 days than those with embryonic mortality of 17-18 days (26.48%) (p=0.001). Females were heavier at chick weight (8.98 g vs. 8.63 g; p=0.033) and at 4 (231.81 g vs. 211.43 g; p<0.000) and 5(260.69 g vs. 231.87 g; p<0.000) weeks of age than males, and had longer left shanks (34.39 mm vs. 33.61 mm; p=0.004).

Purpose: Install the influence of the «small diameter of the egg» on the living mass and the reproductive qualities of chickens of meat crosses and the quail of meat breeds.Materials and methods. The selection was carried out along egg production and mass of eggs and additionally on the average small diameter of 5 eggs by value of ≥0.5σ from the average for the herd, while the evaluation on the basis of the «small diameter of the egg» was carried out in chickens aged 238 days of life, quails — 70 days of life. Calculated the average for each female and the average for the herd. For further reproduction, chickens carrying eggs with a small egg diameter ≥0.5σ from the average for the herd. Studies were held in SibNIP on quail and on the courses.Results. In the initial period of the egg laying, the individual variability of the small diameter of the egg — more than 10% (in the future, the figure decreased). The close correlation rate of the small egg diameter in the first half of the egg laying with such at the end of the bird's operation period was revealed. It has been established that the large diameter of the egg has a positive reliable connection with a lively mass, but negative with egg production. The reliable correlation rate of the small diameter of the egg with a live weight at a 42-day age, as well as with the derivation of eggs. The inheritance coefficients of the small diameter of the egg are comparable to the inheritance coefficients of the mass of eggs and significantly exceed those for a large diameter of the egg. The selection according to the small diameter of the eggs by ≥0.5σ from the average for the herd led to the fact that the chickens of the experimental groups reliably exceeded the live weight in the SB level of 1.57%, in the line G8 — by 1.35%. The superiority of a lively mass of quail of experienced groups was more pronounced than that of the chickens: the Pharaoh breed — by 4.15%, the Texas white breed is 4.22%. In relation to the derivation of eggs, a similar trend was traced. The derivation of eggs in quails of experienced groups was more than 4.59–4.98%; Country, respectively, 4.57–5.22%. Egg production of females of comparable groups of both chickens and quail was almost on the same level, and the difference was unreliable.Conclusion. It was established that a new method of breeding the poultry of the meat direction of productivity allows without decreasing egg production to increase the living mass of chickens of meat crosses by 1.5%, rewinds of meat breeds — by 4%, the derivation of eggs, respectively, by 4–5%. The method is intended for early prediction of females productivity during breeding selection.
