“…Shao et al (2018) demonstrated that cyclic HS (35 °C for 7 days) decreased the BWG, feed intake, and feed/gain ratio of Chinese indigenous broilers (Xueshan broilers). In a study with Thai native chickens, HS exposure also reduced the BWG, but the HS conditions (35 °C for 3 weeks) were not consistent with the current study (Malila et al, 2021). A recent meta-analysis study for fast-growing broilers revealed that the feed intake and feed conversion ratio were not significantly affected by 1-21 days of HS (Andretta et al, 2021).…”

This study was done to evaluate the effects of heat stress (HS) on production performance, redox status, small intestinal barrier-related parameters, cecal microbiota, and metabolome of indigenous broilers. A total of forty female indigenous broilers (56-day-old) were randomly and equally divided into normal treatment group (NT group, 21.3 ± 1.2°C, 24 h/day) and HS group (32.5 ± 1.4°C, 8 h/day) with five replicates of each for 4 weeks feeding trial. The results showed that the body weight gain (BWG) of broilers in HS group was lower than those in NT group during 3–4 weeks and 1–4 weeks (p < 0.05). The HS exposure increased the abdominal fat rate (p < 0.05) but decreased the thigh muscle rate (p < 0.01). Besides, broilers in HS group had higher drip loss of breast muscle than NT group (p < 0.01). Broilers exposed to HS had lower total antioxidant capacity (T-AOC) in serum and jejunum, activities of total superoxide dismutase (T-SOD) in the jejunum, glutathione peroxidase (GSH-Px) in the thigh muscle, duodenum, and jejunum; and catalase (CAT) in breast muscle, duodenum, and jejunum (p < 0.05). Whereas the malondialdehyde (MDA) contents in breast muscle, duodenum, and jejunum was elevated by HS exposure (p < 0.05). Moreover, the relative mRNA expression of Occludin and ZO-1 in the duodenum, Occludin, Claudin-1, Claudin-4, ZO-1, Mucin-2 in the jejunum, and the Claudin-4 and Mucin-2 in the ileum was down-regulated by HS exposure (p < 0.05). The 16S rRNA sequencing results showed that the HS group increased the relative abundance of Anaerovorax in the cecum at the genus level (p < 0.05). Cecal metabolomics analysis indicated 19 differential metabolites between the two groups (p < 0.10, VIP >1). The Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis revealed that the differential metabolites mainly enriched in 10 signaling pathways such as the Citrate cycle (TCA cycle) (p < 0.01). In summary, chronic HS exposure caused a decline of production performance, reduced antioxidant capacity, disrupted intestinal barrier function, and negatively affected cecal microbiota and metabolome in indigenous broilers.

“…An increase in average environmental temperatures has urgently raised global attention as it inevitably impacts the well-being of lives on Earth. For chickens, their physiological response to thermal challenge depends on several factors, including breed, size, and age ( Lu et al, 2007 ; Awad et al, 2020 ; Malila et al, 2021a ). Commercial broilers, meat-type chickens, exhibit more susceptibility to thermal stress than their ancestors ( Tabler et al, 2020 ) and other slow-growing strains ( Washburn et al, 1980 ; Aengwanich, 2007 ; Malila et al, 2021a ).…”

“…An ambient temperature above 30°C is considered sufficient to induce stress among the birds ( Azad et al, 2010 ; Adu-Asiamah et al, 2021 ). The negative impacts of thermal challenge include diminished growth performance ( Azad et al, 2010 ; Quinteiro-Filho et al, 2010 ; He et al, 2018 ; Aslam et al, 2021 ), increased mortality ( Al-Fataftah and Abdelqader, 2014 ), compromised gut health, ( Quinteiro-Filho et al, 2010 ; Awad et al, 2020 ), and deviated meat quality ( Sandercock et al, 2001 ; Lu et al, 2017 ; Malila et al, 2021a ). A recent meta-analysis performed by Andretta et al (2021) highlighted that broilers with increasing age and weight become more sensitive to heat as their heat dissipation area becomes smaller.…”

The objectives of this study were to examine the effects of cyclic thermal stress on histological characteristics of breast muscle and gene expression regarding adipose infiltration and inflammation in breast muscles collected from different breeds of chickens. The birds, from commercial broilers (CB, Ross 308, 3 weeks), native (NT, 100% Thai native Chee, 9 weeks), H75 (crossbred; 75% broiler and 25% NT, 5 weeks), and H50 (crossbred; 50% broiler and 50% NT, 7 weeks), were equally assigned into control or treatment groups. The control samples were reared under a constant temperature of 26 ± 1°C, while the treatment groups were exposed to 35 ± 1°C (6 h per day). After a 20-day thermal challenge, 12 male birds per treatment group were randomly collected for determination of live body weight, breast weight, numbers of growth-related myopathies, and breast meat chemical composition. Histological lesions were evaluated in the pectoralis major muscle immediately collected within 20 min postmortem based on hematoxylin and eosin staining. The results indicated that despite interaction between thermal stress and breed effects, thermal challenge significantly reduced feed intake, live body weight, and breast weight of the birds and increased moisture content in breast meat (p < 0.05). An interaction between the two main factors was found for protein content (p < 0.05) for which control CB showed less protein than the other groups. Heat stress decreased histological scores for adipose infiltration in CB (p < 0.05), but it did not significantly influence such scores in the other groups. CB received histological scores for adipose tissue at greater extent than those for the other groups. Differential absolute abundance of CD36, FABP4, LITAF, PDGFRA, PLIN1, PPARG, POSTN, SCD1, and TGFB1 in the muscle samples well-agreed with the trend of histological scores, suggesting potential involvement of dysregulated fibro-adipogenic progenitors together with imbalanced lipid storage and utilization in the breast muscle. The findings demonstrated that the cyclic thermal challenge restricted growth performance and breast mass of the birds, but such effects attenuated infiltration of adipose tissue and inflammatory cells in the CB breast muscle.

“…Several factors affect the incidence of WB including gender, genotype, growth rate, dietary energy, slaughter weight, early dietary restriction and breast yield/size (Kuttappan et al, 2012;Kuttappan et al, 2016). It is known that an environmental temperature above 30C induces heat stress in poultry (Malila et al, 2021;Rajkumar et al, 2021). Consequently, the adverse impact on meat quality via oxidative damage (Reddy et al, 2018) reduces the process of muscle regeneration and the resulting WB (Aslam et al, 2021).…”

Background: There are few scientific reports of the occurrence of wooden breast (WB) in Thailand. This study aimed to evaluate the incidence and effect of WB on the physical and chemical properties of meat from chickens reared under an evaporative cooling system (EVAP). Methods: A total 124 broiler chickens (BW = 2721.27±273.40 g) were selected from a group of 588 male broiler chickens (at 36 days of age). The WB meat (left site) score of each chicken was identified as being normal, moderate or severe. In order to compare the effect of the WB score on meat quality, based on the number of chickens in the normal group, the number of chickens in the moderate and severe groups were equalised (19 birds/group). The effects of the WB score on pH, colour, drip loss, thawing loss and cooking loss of the meat were observed. Result: The body weight of normal meat, moderate WB and severe WB was 2525.26±221.49, 2683.53±273.17 and 2883.78±211.90 g, respectively. The severe WB score occurred when the body weight (g) was heavier than the normal meat group for 14.19% (P less than 0.01). At 24 hours, the pH, drip loss, cooking loss and water content of the severe WB group was significantly higher, while the protein content in the severe WB group was lower than the normal meat group (P less than 0.01). Moreover, the severe WB group presented higher lightness, redness and yellowness values compared to the normal meat group (P less than 0.01). In conclusion, a larger body of broiler chickens, greater than 14% of the strain’s recommendation induced a severe WB score, which caused poor meat quality.
