“…Similar to the performance results in the present study, HSD was shown to cause decreased FI, FCR, and BW gain, resulting in deteriorated poultry growth performance and welfare (11,12). When the number of birds per unit of space increases, microclimate conditions around the birds deteriorate.…”

“…Quail is a good alternative animal protein due to its low housing, space, and feed requirements as well as diminished waste and higher productivity. Cage density is an important environmental factor affecting production levels and quality in quail meat (11). The goal of quail producers is to achieve a balance between production efficiency and bird welfare.…”

“…Indeed quails have smaller body weight and space requirements are small. In addition to, less waste is produced as compared with other conventional livestock projects, and thus it is not so detrimental to the environment (Faitarone et al, 2005). Laying hens todays are primarily housed in battery cages (also called conventional cages).…”

The current study was conducted to examine the effects of different cage stocking densities and sex on performance and physiological changes of laying Japanese quail reared under hot climate region for a period of 11 weeks (10 to 21 weeks of age). A total number of 600 Japanese quails (400 females and 200 males) at 10 weeks old were randomly distributed in a randomized block design with 4 treatments (71, 59, 50 and 43 quail per cage) or (140, 170, 200 and 233 cm 2 / bird) respectively. Each treatment group was represented by 3 replicates. During the experimental period all birds received 16 hrs of light and 8 hrs of dark. Results indicated that quails kept at low stocking density (233cm 2 / bird) recorded significantly (P≤ 0.05) higher live body weight, egg production, egg mass, feed intake, protein and energy intakes compared with quails kept at other stocking densities. Further, egg weight was not significantly affected by the experimental treatments. However, feed conversion ratio and mortality rate were progressively reduced (P≤ 0.05) with decreasing stocking density. There were significant reductions in plasma total protein fractions by lowering stocking density. Whereas, a significant increase in total lipids, cholesterol, ALT, plasma total calcium and phosphorous with increasing stocking density. While, insignificant differences were observed for HDL, LDL and AST. The results clearly indicated that decreasing stocking density was significantly (P≤ 0.05) decreased corticosterone level. While, IGg increased significantly (P≤ 0.05) due to decreasing stocking density, thus leading to increased susceptibility to resistance of infections. Other physiological traits (i.e., respiration rate, cloacal temperature, skin temperature and heart pulse rate) recorded higher values for quails kept at high stocking density (140cm 2 / bird) compared with those stocked at low stocking densities. On the other hands, sex had no effect on these traits. Traits of egg quality showed insignificant differences for the most, except for yolk index, shell thickness, yolk color and eggs with blood or meat spots. Also, insignificant differences were observed for all carcass characteristics except for live body weight, blood weight and carcass weight percentages. In conclusion based on the obtained results it could be concluded that egg production percentage, egg mass and immunological response improved as the cage space per quail increased. Therefore, it can be recommended that in order to minimize physiological stress in the cages of laying Japanese quail should raised at a density of 233 cm 2 /bird to exhibited superior performance and lowering mortality rate.

“…Such practice is very common and can be seen as aggressive but generally did not interfere in the production system (Leandro et al 2005). The maximization of the production system has brought some issues about the birds welfare (Faitarone et al 2005), once the area per bird is reduced, as well as the feeding area and the water area, causing increase on the stress and at the end, in the final production, as eggs or meat (Carey et al 1995), interfering on the feed consumption and its performance (Pavan et al 2005).…”

In the way to reduce costs in the poultry production, high densities of birds are adopted in the production systems. Such high densities can lead to an inappropriate environment, compromising the welfare and decreasing the animal performance. In this work we aimed to evaluate the effects of different densities on the productive yield, egg quality and immunological aspects of Japanese quails. It was used 816 Japanese quails, during egg production phase, in a random design, with four treatments (121.43 cm 2 /bird; 106.25 cm 2 /bird; 94.44 cm 2 /bird and 85.00 cm 2 /bird) with six repetitions each. Results indicate density did not interfere on egg quality and all treatments can be considered excellent, once the Haugh Unit was 88.03. Therefore, higher densities decline the yield, decreasing the eggs weight (10.35 g), the laying percentage (88%), egg mass (9.16 g) and the week average feed consumption (157.35 g). IgY values were higher at smaller cage density, suggesting birds in this condition presented better immunological condition, related to welfare and stress factors, all linked to immunoglobulins IgY.
