“…In the present experiment the stocking density had no significant effect on carcass parameters, which is consistent with [19] , they reported that stocking density was ineffective on mortality, breast muscle size and carcass quality. The percentage of carcass, thigh, breast and abdominal fat was not affected by stocking density, which is consistent with the study of other researchers [4,21,28,29] .…”

“…The reduction of performance by increasing stocking density can be due to reduced feed intake and thus Decrease received nutrients for maximum growth [3] . By increasing density, the number of birds per unit of floor space increases thus higher efficiency can be obtained, but this economic profit may be at the expense of reduced performance, hygiene and comfort of the bird [4] . In a research [5] investigated the effects of stocking density, chick's sexuality and the amount of metabolizable energy on performance and leg problems in broiler chickens, they stated that the stocking density have severe effects on the growth rate of male broiler chickens before 35 d of age, and male chickens need more space than females to reach marketing age.…”

To investigate the effect of stocking density on productive traits, blood parameters and immunity, 1305 Ross 308 male broiler chicks (initial weight: 45±1.5 g) were used as a completely randomized design with 2 treatments and 15 replications. Treatments included 1) 12 chicks per pen 2) 18 chicks per pen (1.2x1.2 m 2). The results were recorded in three periods of 0-24, 25-42 and 0-42 d. From 0 to 24 d of age, the stocking density had no significant effect on feed intake and body weight gain (P>0.05), but feed conversion ratio significantly decreased in 12 chicks density group (P<0.05). Feed conversion ratio, body weight gain and feed intake were improved significantly in 12 chicks compared to 18 chicks density for 25-42 and 0-42 periods (P<0.05). The production per m 2 was significantly higher in 18 chicks density group at 0-42 d period (P<0.05). High stocking density caused to increase the moisture content of bedding in 4-6 th weeks of age (P<0.05). Stocking density had no significant effect on mortality percentage (P>0.05). Also the relative weights of spleen, bursa of fabricius, abdominal fat, thigh and breast were not affected by experimental treatments (P>0.05). Increasing the number of chicks per m 2 caused to increase heterophile count and decrease lymphocyte count and increase heterophile to lymphocyte ratio (P<0.05). Newcastle's titer was not affected by treatments (P>0.05). Given that performance indices were better under low stocking density, but live body weight per m 2 was significantly higher in 18 chicks density group (32%), it's seems economically 18 chicks per m 2 is the best stocking density.

“…It should be noted, however, that some producers did not keep good records. Also, Our results in final body weight are disagreement with these reported by Ghosh et al (2012), Nogueira et al (2013), Cengiz et al (2015), Adeyemo et al (2016), Farhadi et al (2016) and Kryeziu et al (2018), in broiler chicks the average final body weight (kg) at 42 days old ranged 1.90-2.04 kg. Although our results are disagreement with Mbuza et al (2017) in mortality rate (14%) of broiler chicks before 4 weeks and after 4 weeks it drops to 9%, our explanation are agreement with those he reported.…”

This study was carried out to assess the current status of broiler production under semi-intensive system in Egyptian rural sector. Forty three of semiintensive broiler production system producers were chosen using random sampling method. The study revealed that the flock size in the semi-intensive broiler production system ranged from 2000-3000 with average 2393 chicks. Interestingly, males were the only owner of flocks for the whole system. However, the majority of the producers (65.12%) had free jobs and 58.14% had attained high education level. For both producers were used commercial strains. Clearly, the producers used commercial rations represent 72.09%, while the other 27.91% used homemade (manual) rations. In general, the results indicated that there were insignificant differences detected in total feed intake/chick between the two governorates. The major constrains found in the studied areas, in order of their importance, were lack of access to formal credit, unavailability of feed, high cost of chick price, lack of quality feeds, high feeding cost, lack of training labours, diseases, lack of marketing information, high production elements cost and lack of veterinary services. Therefore, to improve semi-intensive broiler production system in Egypt, the experts from the government, research institutes, universities, nongovernment organizations (NGOs) and other relevant sectors need to work in a collaborative manner in order to allow sustainable production and fight challenges jointly whenever they arise.

“…On a commercial scale, McKeith et al (2020) found no significant effect of standard stocking density (0.23 m −2 per bird) and low stocking density (0.27 m −2 per bird) in respect to the growth rate and feed efficiency of broiler chickens. The growth performance of broilers was also unaffected up to a stocking density of 14 birds m −2 in the study of Adeyemo et al (2016). A more recent study by Greene et al (2021) instead found that increasing the stocking density from 12 to 22 birds m −2 reduced the time to reach 2 kg live weight.…”

“…Furthermore, Tong et al (2012) found that the stocking density had no effect on the water loss rate, shear force and meat color of broiler meats. Adeyemo et al (2016) further reported that the proportions of prime cuts (thigh, drumstick and breast), abdominal fat and meat protein were comparable between birds on 10 and 14 birds m −2 . The carcass characteristics of broiler chickens were also unaffected up to a stocking density of 14 birds m −2 in the study of Adeyemo et al (2016).…”

Abstract. Stocking broilers at a high density has been a strategy to optimize the area of the cage and hence increase the efficiency of broiler production. If the environmental (microclimate) conditions and rearing management are not properly managed, stocking broilers at a high density may, however, result in stressful conditions that are harmful for the production, health and welfare of broilers. To ameliorate these unfavorable effects of overcrowding stress, dietary interventions have been conducted. Probiotics, prebiotics, synbiotics, plant-derived products, vitamins, propolis, amino acids, fatty acids, etc. have been supplemented in diets to deal with the harmful impact of stress induced by a high stocking density of broilers. This review covers the detrimental effects of overcrowding-induced stress on broiler development and attempts to ameliorate those negative effects by dietary interventions.
