“…Water consumption was similar (P = 0.6603) at both temperatures (Table 2), where the birds were kept at a temperature considered above the thermal comfort zone (Castro et al, 2017;Soares et al, 2019b), which can cause changes in physiological variables, such as increased respiratory rate and rectal and surface temperature (Nunes et al, 2014). Increasing the stewater demand, but raising quails at a temperature of 32 °C for 12 h, followed by the availability of milder temperatures during the night period, allowed similarity in this consumption, demonstrating the adaptability of quails to tropical climates, where the higher water consumption during times of stress may have been offset by lower consumption at night.…”

“…Egg production was counted, and,in the end, the quails were weighed for homogeneous distribution in the experimental units, considering the body weight and the average laying rate of the birds. After distribution, the chamber temperatures were adjusted to 24.0 ± 1.0 °C within the thermal comfort zone and 32 ± 1.2 °C above the thermal comfort zone (Castro et al, 2017;Soares et al, 2019b). These values were maintained for 12 hours (7:00 to 19:00), and the chamber doors were opened from 19:01 to 6:59 at room temperature (22 ± 2.0 °C), simulating the environmental conditions of the semiarid region.…”

The objective of this study was to evaluate the productive performance, egg quality and the morphometry of the organs of Japanese quails (Cotournix cotournix japônica) when kept in comfort and under thermal stress. 192 nine-week-old quail were used, distributed in a completely randomized design at two temperatures (T1 = 24 °C and T2 = 32 °C), with 12 replicates of eight birds each, with an experimental period of 63 days, divided into three 21-day periods. Feed intake (g fowl-1 day-1), water consumption (mL fowl-1 day-1), egg production (%), egg weight (g), egg mass (g fowl-1 day-1) and feed conversion (kg kg-1 and kg dozen-1). Laying quails after their production cycle are marketed as beef animals. It is observed that the average final live weight was reduced (P = 0.0362) by 27.58 g in birds kept at a temperature of 32 o C, which can compromise its commercial value. The feed intake of the birds was reduced (P = 0.0051) by 14.75% with an increase in ambient temperature. Birds kept at a temperature of 32 o C for 12 h daily showed a reduction in feed intake, final weight, yolk, and gizzard weight, but without affecting egg production, weight and mass.

“…Studying microscopic changes will elucidate underlying physiological and functional derangements caused by heat stress. For example, histochemical staining of the brain will elaborate on the neurons involved in the behavioural changes seen in Japanese quail exposed to heat stress (Soares et al, 2019). But no immunohistochemical study of the brain was identified by this scoping review.…”

Background Heat stress negatively affects poultry welfare, including the Japanese quail, especially in sub-Saharan African countries. The quail is vital to research and protein food security, which are affected by global warming. This study identified and reviewed the literature on the impact of heat stress on the Japanese quail organs to provide context for the problem and ways to mitigate it. Main body Eligible studies for this scoping review must be primarily animal-based experiments that include Japanese quail exposure to acute or chronic heat stress. Systematic reviews, theses and dissertations that meet these criteria were also eligible for use in this review. Reports that involved other types of quail species, eggs and or cell lines were not eligible and were excluded. The databases that were searched include MEDLINE (via PubMed), SCOPUS, CAB Abstracts (via CAB Direct) and Web of Sciences (All databases). A total of 4598 records were identified. After removing 105 duplicates, 4461 and 9 were excluded during the level 1 and 2 screening, respectively. Finally, 24 papers were included for data extraction. All eligible studies were primary animal experiments, and the average heat stress temperature level was 35.3 °C. Morphological findings of this scoping review include macrovesicular steatosis in the liver, necrosis of kidney tubular cells, dead and abnormal sperm cells in the testis, lung congestion, and neuronal degeneration resulting from heat stress exposure. Conclusions Heat stress negatively impacts the organs of the Japanese quail, causing cell death in the liver, brain and testis, which will affect the production and survival of the Japanese quail. In addition, some cost-effective dietary strategies tested in mitigating heat stress were recommended.

“…Supplementation with magnesium oxide and Mg protein promoted an increase in weight gain and feed consumption of Japanese quails kept under cyclic temperatures of thermal stress (Tao et al, 1983). Laying quails raised in high temperatures may have a reduction in their productive performance and egg quality (El-Tarabany et al, 2016;Silva et al, 2017;Soares et al, 2021a), and to maintain homeostasis, quails alter their ingestive behavior (Castro et al, 2017;Soares et al, 2021b) and raise the rectal and surface temperatures, and the heart and respiratory rates (Rodrigues et al, 2016).…”

The objective to evaluate the effects of magnesium supplementation in the water of Japanese quails (Coturnix coturnix japonica) on physiological variables and egg quality with the birds kept in a thermoneutral environment and under thermal stress. Three hundred ninety-four (394) quails were used, distributed in a completely randomized 2×4 factorial design (2 temperatures: 24 and 32ºC, and 4 levels of magnesium: 50, 150, 250 and 350 mg L-1), with six replicates and eight birds per experimental unit. The respiratory rate (P<.0001), head temperature (P<.0001), wing temperature (P<.0001), foot temperature (P<.0001), back temperature (P<.0001), body surface temperature (P<.0001) and average body temperature (P<.0001) showed significant differences between the temperatures tested. With the exception of head temperature (P=0.0045), the other variables did not change their values with the increase in the level of magnesium in the water. Egg mass showed a significant difference (P=0.0072) as a function of the level of mannesium in the water. The temperature of the head was higher in birds consuming water with higher levels of magnesium, causing an increase in respiratory rate, and head, wing, foot, back, average surface and body temperatures in birds under thermal stress.
