“…Although the etiology of the WS has not been fully elucidated, it is suggested that the onset of the development of WS occurs due to insufficient vasculature to support the needs of the rapidly growing pectoralis major muscle. Subsequently, a localized hypoxia develops resulting in the degradation of muscle fibers that creates an imbalance between degradation and regeneration of muscle fibers that are gradually replaced by fat deposits appearing as WS on the pectoralis major muscle (Ahsan and Cengiz 2020). This is the first study investigating the effect of HS on the incidence and severity of WS.…”

“…All these effects contribute to lowered nutrient digestibility and impaired nutrient absorption resulting in poor body weight and growth performance of broiler chickens (Farag and Alagawany 2018;Zaboli et al 2019;Patra and Kar 2021). It has been known that low body weight in broiler chickens may lower the development of WS (Kuttappan et al 2013b;Bailey et al 2015;Dalle Zotte et al 2015;Russo et al 2015;Ahsan and Cengiz 2020). Conversely, HS gives rise to the development of oxidative stress by increasing the lipid peroxidation and reactive oxygen species (ROS) at tissue and cellular level (Bruskov et al 2002;Mujahid et al 2005).…”

A study was conducted to evaluate the effect of cyclic or chronic heat stress (HS) on the incidence and severity of white striping (WS) and histopathological changes in breast muscle of broiler chickens. One hundred eighty 1-day-old male chickens were randomly assigned to three research groups: control (standard temperature throughout the experiment), cyclic HS (32 ºC between 0800 and 2000 h from day 21 until the end of the experiment), and chronic HS (32 ºC from day 21 onwards). Cyclic and chronic HS groups showed a significant (P < 0.05) decrease in body weight gain and feed intake and poor feed conversion ratio in grower, finisher, and overall period. Serum biochemical profile was not different among the groups except globulin and P which were significantly higher (P < 0.05 and P < 0.001, respectively), in cyclic and chronic HS groups. Overall, WS incidence was numerically higher in control birds followed by chronic HS and cyclic HS birds, respectively. The chronic HS group had a lower incidence of mild (score 1) and a higher incidence of severe (score 2) WS lesions compared to control and cyclic HS groups. Histopathological analysis revealed that broilers subjected to chronic HS showed increased severity of myodegenerative changes, perivenular CD3 + cell infiltration, and lipidosis compared to control group. However, control and cyclic HS groups were not different in terms of histopathological lesions. In conclusion, this study confirms that cyclic or chronic HS may adversely affect the growth performance and that chronic HS may increase the severity of WS in broiler chickens.

“…Previous findings indicate that reduced dig. Lys diets can have an appetite-depressant effect in young broilers [ 35 ], which is mediated by variations in the plasma levels of Lys [ 36 , 37 ]. On the other hand, the reduction of Lys concentration could have affected the ratio between Lys and other dietary components, such as the metabolizable energy, which might have played a role in altering voluntary feed consumption.…”

The present study aimed at assessing the impact of lysine restriction performed during different feeding phases on growth performances, meat quality traits and technological properties as well as on the incidence and severity of breast muscle abnormalities. For this purpose, a total of 945 one-day-old Ross 308 male chicks was randomly divided into three experimental groups: CONT, fed a four feeding phases commercial diet, GRW I, and GRW I + II fed CONT diet with the depletion of synthetic lysine during grower I and grower I and II feeding phases, respectively. Productive performances were recorded throughout the whole rearing cycle and the incidence of breast muscle growth-related abnormalities assessed at slaughter (49 d) on 280 breasts/group. Quality traits and technological properties of breast meat were measured on a total of 54 Pectoralis major muscles. Lysine restriction only marginally affected the productive performances and the quality parameters of breast meat. The increased (p < 0.05) solubility of the protein fraction along with the remarkably higher (p < 0.05) anserine content found in GRW I + II suggests an increased energy requirement in the pectoral muscles belonging to lysine-restricted birds and supports the hypothesis of a reduced protein synthesis taking place within these muscles.

“… Alnahhas et al (2016) showed that the average incidence of WS was about 50% in examined birds’ population. Ahsan and Cengiz (2020) revealed that the incidence of WS was lowered by reducing the level of lysine in the grower feed. It was found that low level of lysine in the feed lowered the feed intake as well as the growth rate of the birds, therefore, the severity and incidence of WS reduced.…”

The aim of this study was to assess the occurrence of white striping (WS), wooden breast (WB), and WS combined with WS/WB muscle abnormalities in broilers (Ross 500) at different slaughter ages (34, 41, and 48 d). In addition, the influence of these muscle abnormalities at different slaughter ages on quality characteristics (physical dimensions, pH, color index, and chemical composition) was studied. Overall occurrence of muscle abnormalities was 45%, 92%, and 100% at slaughter ages of 34, 41, and 48 d, respectively. It was found that about 39% from the occurrence of muscle abnormalities was not similar in the same bird (left and right fillets). Breast fillets affected by muscle abnormalities had significantly (p<0.05) higher weight than normal fillets. At slaughter age of 34 d, normal fillets had significantly higher L* (67.37 vs. 61.73 and 63.05, p<0.05), lower a* (3.25 vs. 4.87 and 5.18, p<0.05) and b* (4.02 vs. 5.20 and 5.99, p<0.05) than WS and WS combined with WB fillets; respectively. The changes in chemical composition due to muscle abnormalities were more significant at high slaughter age than at low slaughter age. In conclusion, the occurrence of muscle abnormalities was strongly influenced by slaughter age. Moreover, breast fillets affected by muscle abnormalities had different quality characteristics (proximate composition, color traits, and dimensions) in comparison to normal fillets.
