Meat quality of broiler chickens processed using electrical and controlled atmosphere stunning systems

Assessing meat quality and textural properties of broiler chickens: the impact of voltage and frequency in reversible electrical water-bath stunning

“…It is also reported that prolonged storage may lead to the growth of Pseudomonas-associated spoilage bacteria, producing a slime layer capable of reducing metmyoglobin to deoxymyoglobin, thus resulting in a lower yellowness value ( Leygonie et al, 2011 ; Hayat et al, 2021 ). Previous studies reported have shown that there was no significant impact of different electrical frequencies ( Lafuente and López, 2014 ), different electrical stunning methods ( Huang et al, 2014 ; Riggs et al, 2023 ), different electrical voltages ( Huang et al, 2017 ), different electrical amperage ( Sirri et al, 2017 ). However, the outcome of this study was in agreement with a study conducted by Siqueira et al (2017) , which showed that broilers stunned at a higher frequency (650 Hz) resulted in higher yellowness value compared to broilers subjected to low frequency (300 Hz).…”

“…The results obtained do not align with the findings by Huang et al (2017) and Sirri et al (2017) , in which no significant difference in lightness value was observed between different stunning voltage and electrical amperage. However, regarding the stunning procedure, Riggs et al (2023) reported that the lightness value of the electrically stunned meat was significantly lower than that of the controlled atmosphere stunning.…”

Inspection of chicken wings and legs for animal welfare monitoring using X-ray computed tomography, visual examination, and histopathology

“…Therefore, it is important to determine the type of stunning method, when analyzing wing or legs injuries in chicken. For example, in another research the observed percentage of damaged wings was significantly higher (3.6 vs. 2.2%) in chickens stunned in controlled atmosphere stunning compared to electrical stunning ( Riggs et al, 2023 ). This difference can be probably explained by excess of wings flapping leading to injuries observed in controlled atmosphere stunning ( Riggs et al, 2023 ).…”

Large-scale genomic and transcriptomic analyses elucidate the genetic basis of high meat yield in chickens

“…WB and WS were scored and classified by subjective assessment as described in previous studies (normal breast scored 0, mild WB/WS scored 1, moderate WB/WS scored 2) [16] , [17] . Drip loss (DL) and compression force (CF) were measured as previous reports [18] , [19] . All the phenotypic data were distributed within the range of the mean ± 3 standard deviations and passed quality control for subsequent GWAS analysis.…”
