“…In a study on female Japanese quail that were housed in 38˚C for 8 hours a day, researchers found no difference in red blood cell count, concentration of hemoglobin, pack cell volume %, or white blood cells when compared to those not challenged with heat stress (temperature unreported) [42]. This is contrary to others who reported that Japanese quail were sensitive to high environmental temperatures and the metabolic stress response was triggered at temperatures higher than 25˚C [15]. Contrary to the findings of the current study, hematocrit of heat stressed broilers at 43˚C were observed to decrease due to the damage of the red blood cells [34].…”

“…When there is excess loss of CO 2 , the PCO 2 will decrease along with a decrease in H 2 CO 3 in the blood due to an increase of HCO 3 release from the kidneys and reduction of H + excretion to maintain acid-base equilibrium [15]. Researchers found a decrease in blood PCO 2 in heat Only families from TNS that had high fitness in HSS were mated.…”

Changes in Japanese quail (Coturnix coturnix japonica) blood gases and electrolytes in response to multigenerational heat stress

et al. 2023

The average surface temperature is predicted to rise 0.5 to 6˚C by the year 2100. When Japanese quail (Coturnix coturnix japonica), a source of protein for many, are subjected to heat stress, their blood acid-base equilibrium and ability to regulate electrolytes may change. This disequilibrium may influence egg-shell quality, enzyme functions, and synthesis of tissue proteins. To determine effects of multi-generation heat stress on Japanese quail, the following treatments were applied (1) control (TN, non-sibling random mating at thermoneutral temperature [22.2˚C]); (2) thermoneutral siblings (22.2˚C, TNS); (3) heat stress (HS, non-sibling random mating at 31.1˚C); and (4) heat stressed siblings (HSS, siblings of TNS with high feed conversion ratios (FCR), 31.1˚C). Body weights (BW), blood gases, and electrolytes of quail were measured during the first 4 hours (acute) and after 3 weeks (chronic) of heat exposure (31.1˚C) in generation 10. ANOVA was used to determine statistical significance at P≤0.05. Models included treatments, length of exposure, sex, and their interactions. Results showed that acute and chronic heat stress did not have a clear effect on blood electrolytes, acid-base regulation, and oxygen transport. However, acute HSS males or females were significantly different than chronic TN males in BW, PCO2, PO2, sO2, and Na+. Chronic HS males and females did not have significantly different blood electrolytes, acid-base regulation, and oxygen transport than chronic HSS males and females. Thus, selection for low FCR in heat stress at 31.1˚C did not incur a fitness advantage when considering these parameters. Sexually mature males had significantly higher levels of hematocrit and hemoglobin compared to sexually immature quail and sexually mature females. Future studies using higher temperatures (32 to 34˚C) could inform producers when to expect significant physiological changes in quail, lending to adaptions of feeding regiments according to environmental temperature and age.

“…In the hens, the maintenance of the acidbase balance was found to exert a strong influence on the physiological and biochemical aspects which, in turn, could affect the metabolic processes related to growth, disease resistance, survival under stress and animal performance (BRETÂS et al, 2010). MORAES et al, (2019) reported that sodium, potassium, and chloride were fundamental to the maintenance of osmotic pressure and the acid-base balance of the body fluids. Silva et al The electrolytes present in the birdfeed were observed to alter the acid-base balance and, thus affect the metabolic processes concerned with growth, production, health, stress, and well-being (WANG et al, 2020).…”

This study was done to determine the best value of the total electrolyte balance (BET) concerning the variables of performance and egg quality of the laying hens. We investigated 240 Hy-Line Brown laying hens, of 30 to 46 weeks of age, adopting the completely randomized experimental design, which included five treatments (1000, 1250, 1500, 1750 and 2000 μeq / kg), 8 repetitions and 6 birds per unit. The performance and quality of the birds’ eggs were evaluated in the different treatments. The results were subjected to the analysis of variance and, wherever significant effect was noted, the regression equations were estimated, taking into account the electrolyte balance (μeq / kg) as a concomitant variable, applying the SAS statistical program (2001). The consumption, production, and feed conversion variables by dozen eggs, final bird weight, egg density, yolk color, Haugh Unit, albumen weight, shell weight, and egg weight, were found to be unaffected by the experimental BET values. The values of the feed conversion per egg mass, yolk weight and uniformity were affected by the different BETs. The electrolyte balance values showing minimum feed conversion, higher yolk weight, and better uniformity were, respectively, BET = 1400, 1330, and 1250 in μeq / kg of loads at the different temperatures. From the regression equations, the value indicated was BET=1390 for the 30- to 46-week-old laying hens. The electrolyte balance of the diet was found to affect the laying hens in terms of performance and egg quality.
