“…HS has been proven to negatively affect poultry growth, intestinal tness, immune system function, and production e ciency (Ahmad et al, 2022). In this study, HS decreased ADFI and ADG, part of the reason was probably because broilers had to lower feed intake, and water consumption to reduce heat production under high temperatures.…”

“…With the rise in global ambient temperatures, the poultry industry in numerous countries was seriously threatened, because poultry covered by feathers, lack of sweat glands, and the release of body heat was inhibited, which resulted in a low tolerance to high temperature (Ahmad et al, 2022). Besides, heat stress (HS) from high temperatures has been reported to reduce animal feed intake and performance and caused economic loss (Wang et al, 2022).…”

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.

“…Thus, probiotic supplementation may modify the gut microbiota composition and alter stress response concomitantly. While there has been substantial work on the effect of probiotics on heat stress in poultry [ 53 , 54 ], there is a paucity of information on the influence of the supplement on response to non-thermal stressors. The present findings suggest that, as measured by CORT and HLR, probiotics supplementation can alleviate stress attributed to catching and crating in ducks.…”

Catching and crating may elicit stress and fear reactions in poultry because the procedures involve human contact and exposure to a novel environment. This study determined the effects of dietary probiotic supplementation on physiological stress, underlying fear, and growth performance of Pekin ducks subjected to catching and 4 h of crating. The study used a 2 × 2 factorial arrangement; the main factors were diet (basal or basal + probiotic) and crating durations (0 or 4 h). From 1 to 21 days of age (doa), birds were fed a basal or basal + probiotic (CLOSTAT® (Bacillus subtilis) (Kemin Industries, Inc., Des Moines, IA, USA), 1 g/kg) diet. At 21 doa, an equal number of ducklings from each dietary group were caught and crated for 4 h or left undisturbed in the home pens. Birds were examined for serum corticosterone (CORT), heat shock protein (HSP) 70, creatine kinase (CK), triglyceride (TG), glucose (GLU), cholesterol (CHOL), and lactate (LAC) concentrations, heterophil to lymphocyte ratios (HLR), tonic immobility (TI) duration, open-field (OF) test, body weight (BW), and feed conversion ratios (FCR). Diet had no significant (p > 0.05) effect on CORT among the non-crated ducks. However, after catching and crating, birds fed the control diet had significantly (p < 0.05) higher CORT than their probiotic-supplemented counterparts. Catching and crating significantly (p < 0.05) elevated HSP70, HLR, GLU, and CHOL but reduced TG in ducks. Birds fed the probiotic-supplemented diet showed significantly (p < 0.05) lower HSP70, HLR, TG, and CK than those fed the control diet. Probiotic-supplemented ducks showed reduced fear-related behaviours, including TI durations, ambulation latency, and body shaking. Diet had a negligible effect on body weights and FCR of ducks at 21 doa. In brief, catching and crating for 4 h augmented Pekin ducks’ physiological stress and fear reactions, and supplementing birds with probiotics was beneficial in ameliorating these detrimental effects.

“…Most of these stressors will cause oxidative stress to the intestinal epithelial cells ( Durand et al., 2022 ). One such stressor which is of particular importance in poultry production is heat stress ( Ahmad et al., 2022 ). Nutritional stressors can also trigger intestinal inflammation, such as excess protein in the feed.…”
