“…The significant effects of stocking density on feed consumption during the rearing period were in agreement with previous studies (Yakubu et al, 2010;Beg et al, 2011;Rambau et al, 2016;Siaga et al, 2017), namely bodyweight gain during the starter and grower periods, and feed conversion ratio during the finisher period, These studies indicated that high stocking densities reduced feed consumption, bodyweight gain and market weight, and improved feed conversion ratio. However, the extent of reduction or improvement depended on how high the particular density was.…”

“…Several studies have been conducted on the effects of stocking density on broiler performance, but the results have been conflicting. Some studies showed no significant influence of stocking density on broiler performance (Buijs et al, 2009;Rambau et al, 2016) while others demonstrated adverse effects of high stocking densities (Beg et al, 2011;Tong et al, 2012;Ligaraba et al, 2016;Siaga et al, 2017). Others, on the other hand, reported improved broiler performance with increased stocking density (Feddes et al, 2002).…”

The current study investigated the effects of sex and stocking density and their interaction on growth performance and carcass characteristics of broiler chickens in a semi-arid subtropical environment. A total of 1008 day-old Cobb Avian48 chicks, namely 462 males and 546 females, were reared at final stocking densities of 30, 35, and 40 kg bodyweight per square metre (BW/m 2) corresponding to 44, 51 and 59, and 52, 61 and 69 chicks per pen for males and females, respectively, during a 42-day production period. The experiment was a 2 × 3 factorial completely randomized design, with each sex-stocking density combination being replicated three times. After the initial weighing, the birds were weighed individually [grams (g)] each week until the 42 nd day. At day 42, four birds from each pen were randomly sampled and slaughtered, and carcass characteristics were measured after 48 hours, and expressed as percentages of bodyweight. Growth performance and carcass characteristic parameters were subjected to analysis of variance using the general linear model procedures of Minitab statistical software version 17. Treatment means were compared using Tukey's test (at α = 0.05). Males gained more weight and were significantly heavier at slaughter age (2649 ± 43.1 g) than females (2270 ± 43.1 g). There was a progressive reduction in feed intake with increasing stocking density, but neither sex nor stocking density influenced feed conversion ratio and mortality rate. Sex significantly affected dressing percentage and carcass parts percentages, namely breast, neck, shank, heart and abdominal fat and thigh, liver and gizzard. On the other hand, stocking density significantly influenced dressing percentage and carcass parts percentages such as breast, thigh, drumstick, neck, shank, liver and gizzard. There was a significant sex x stocking density interaction effect on percentages of thigh and liver. It is therefore suggested that for efficient 42-day production cycles of broilers in the subtropics, Cobb Avian48 males reared at the stocking density of 40 kg BW/m 2 could be considered the best option.

“…Cravener et al, (1992) showed that stocking density at 0.05m 2 /bird decreased significantly carcass weight compared to those stocked at 0.07, 0.09 and 0.11m 2 /bird. Beg et al, (2011) manifested that the dressing % was significantly higher when stocked broiler at 8 and 10 birds/m 2 compared with those stocked at 12 or 14 birds/m 2 .…”

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.

“…De hoeveelheid water verbruikt door kippen wordt beïnvloed door een aantal factoren (Manning et al, 2007a;2007b), die mogelijk cumulatief of multiplicatief kunnen werken; dergelijke combinaties van factoren zijn echter weinig onderzocht (Castro et al, 2009;Beg et al, 2011). Het is gangbare praktijk om het waterverbruik van de vleeskuikens te controleren door een schatting van het aantal liters per 1000 vleeskuikens per dag (DEFRA, 2002;ACP, 2006).…”
