“…High temperatures in broiler chicken rearing cause, among other things, the development of oxidative stress, which is recognised as a primary factor that reduces production performance (Muchacka et al, 2016). This is confirmed by the study of Behboodi et al (2021), who found the emergence of oxidative stress in broiler chickens exposed to elevated temperatures and demonstrated its negative effects on feed intake, daily weight gain, percentage of legs and abdominal fat in the carcass. Phytonutrients are believed to enhance immunity and improve gastrointestinal function, hence there is increasing interest in the use of herbs and medicinal plants in poultry nutrition to improve the health and productivity of birds exposed to stress (Barbarestani et al, 2017).…”

The aim of the present study was to determine the effect of rearing technology (rearing system and dietary supplementation with a mixed herbal extract) on the production results, selected physiological and blood parameters, and welfare of broiler chickens during the summer production cycle. In the CON and HE groups, broiler chickens were kept on litter without access to free range; additionally, in the HE group, birds from 22 to 42 days of rearing received a mixed herbal extract (50% Melissa officinalis L. and 50% Urtica dioica L.) in the amount of 2 ml/l of water to drinkers with water. In the AP group, birds were reared on litter with access to pasture. During the experiment, production performance and body temperature of the birds were monitored. Blood was also taken from birds in each group and the H:L ratio, levels of corticosterone, glucose and thyroid hormones were determined. The application of 2 ml/l of mixed herbal extract to the drinking water did not improve the production results, not did it affect the physiological indices of the birds studied. The addition of 2 ml/l of mixed herbal extract to the drinking water only resulted in lower corticosterone levels in the blood of the chickens on day 35 of the experiment. The free-range housing system had a negative effect on the slaughter performance of the broiler chickens. However, housing with access to the free range resulted in lower body temperature, lower mortality, as well as lower glucose, corticosterone and a narrower H:L ratio in the blood of the chickens during the period of increasing air temperature. It can therefore be concluded that housing with access to a free range reduces stress levels and thus improves the welfare of broiler chickens during the summer production cycle compared to confined housing. Comparing the rearing technologies used in the study, it was found that the free-range housing system contributed more to improving the comfort of broiler chickens during the summer than dietary supplementation with the tested herbal mixture extract.

“…It was demonstrated that the addition of VC to broiler diets under HS reduced triglycerides and LDL, and increased serum HDL (Erfani et al, 2021). Moreover, a signi cant drop in serum triglyceride, cholesterol, very-low-density lipoprotein and LDL was observed in combination with the addition of Bet (Behboodi et al, 2021), However, in our study, HS had no effect on most of the indicators which evaluate tissue injury, and the addition of VC and /or Bet had no signi cant differences between the groups, this discrepancy was likely due to different application approaches, levels of utilization, environmental differences, such as level of hygiene, duration of exposure to heat, or extent of HS. Interestingly, in this research, HS signi cantly increased serum UA and D-BIL levels, which commonly used serum markers for assessing liver and kidney function, this result may be related to the alteration of protein metabolism and the disruption of the synthesis and excretion mechanisms in broilers during HS (Luo et al, 2018).…”

For broiler’s health, heat stress (HS) poses a significant challenge. This study investigates the potential of vitamin C (VC) and/or betaine (Bet) to enhance growth performance, regulate serum metabolic parameters, and bolster antioxidant function aiming to mitigate the impact of cyclic HS on broilers. Two hundred Ross 308 broilers at 28 days of age were randomly assigned to five groups. The control group, housed at 24 ± 1℃, was fed a basal diet. High-temperature treatment groups, housed at 32 ± 1℃, received a basal diet with 0 (HS group), 250mg/kg VC (HSVC group), 1000mg/kg Bet (HSBe group), and 250mg/kg VC + 1000mg/kg Bet (HSVCBe group). On day 42, assessments were made on growth performance, muscle quality, serum biochemical parameters, and antioxidant function. Results revealed that HS significantly lowered (P < 0.05) average daily feed intake (ADFI), the degree of redness (a*) in pectoral and leg muscles, and serum total superoxide dismutase (T-SOD) level. It also reduced (P < 0.01) average daily gain (ADG), and serum total antioxidant capacity (T-AOC) level, while increasing (P < 0.05) shear force, serum direct bilirubin (D-BIL), uric acid (UA), and malondialdehyde (MDA) levels compared with the control group. Dietary supplementation of VC and Bet, either alone or in combination, significantly decreased shear force and serum UA level, while increasing ADG and the level of T-AOC, and T-SOD in serum antioxidant compared with the HS group (P < 0.05), with the combination yielding the most pronounced effects. In conclusion, the addition of VC and/or Bet to the diet proves effective in enhancing the growth performance of HS-exposed broilers through the positive regulation of serum chemical metabolism parameters and the alleviation of oxidative damage.

“…The use of plant extracts has gained precedence as a nutritional strategy to ameliorate thermal stress in poultry owing to their ease of availability, potency, and numerous biological effects ( 160–168 ). In recent times, several plant-based and alternative substances with bioactive properties have been utilized as feed additives and nutritional modifiers for heat stress mitigation in poultry.…”

Heat stress is a threat that can lead to significant financial losses in the production of poultry in the world’s tropical and arid regions. The degree of heat stress (mild, moderate, severe) experienced by poultry depends mainly on thermal radiation, humidity, the animal’s thermoregulatory ability, metabolic rate, age, intensity, and duration of the heat stress. Contemporary commercial broiler chickens have a rapid metabolism, which makes them produce higher heat and be prone to heat stress. The negative effect of heat stress on poultry birds’ physiology, health, production, welfare, and behaviors are reviewed in detail in this work. The appropriate mitigation strategies for heat stress in poultry are equally explored in this review. Interestingly, each of these strategies finds its applicability at different stages of a poultry’s lifecycle. For instance, gene mapping prior to breeding and genetic selection during breeding are promising tools for developing heat-resistant breeds. Thermal conditioning during embryonic development or early life enhances the ability of birds to tolerate heat during their adult life. Nutritional management such as dietary manipulations, nighttime feeding, and wet feeding often, applied with timely and effective correction of environmental conditions have been proven to ameliorate the effect of heat stress in chicks and adult birds. As long as the climatic crises persist, heat stress may continue to require considerable attention; thus, it is imperative to explore the current happenings and pay attention to the future trajectory of heat stress effects on poultry production.
