“…demonstrated an increase in EE content of breast meat of broiler chickens fed low ME diets. In contrast, feeding low dLys diets had no effect on the breast meat composition of Aseel chickens except lowered crude ash 46 . It is known that WS occurs due to the myofiber degeneration followed by gradual replacement of degenerated myofiber (protein) by the adipose tissue.…”

Intermittent dilution of dietary digestible lysine lowers the incidence of white striping by suppressing the growth, lipid synthesis, and muscle damage in broiler chickens

et al. 2022

BACKGROUND White striping (WS) is a myopathy of breast muscle (Pectoralis major) that affects the quality and consumer acceptance of breast fillets of broiler chickens. Previous studies have shown that intermittent dilution of dietary nutrients suppresses the development of WS on the breast muscle of broiler chickens. However, the mechanism by which these interventions reduce the occurrence of WS remains inconclusive. In this study, we adopted intermittent reduction of dietary digestible lysine (dLys) density or metabolizable energy (ME) and amino acid (AA) density using chemical and fatty acid composition of breast fillets, and blood metabolites to understand the mechanism while histopathology and immunohistochemistry of breast muscles were used for confirmation. RESULTS Occurrence of WS was lower in broiler chickens fed 85% dLys diets in comparison with other groups. Crude protein and ether extract in breast meat of 85% dLys groups were greater (P < 0.001) and lower (P = 0.010), respectively. Serum concentrations of lipid metabolites and enzymes were lower in broiler chickens fed 85% dLys diets than control group (P < 0.05). Feeding 85% dLys diets had low degree of myodegeneration and necrosis, inflammation, lipid deposition, infiltration of T‐lymphocyte (CD3+) and macrophages (Iba‐1+), and low expression of heat‐shock protein 70 (HSP70) than other groups (P < 0.001). CONCLUSION Dilution of dietary dLys to 85% of the required quantities reduces the development of WS in broiler chickens by slowing the growth, lipid synthesis, and muscle damage confirmed by lower extent of histopathological lesions. © 2022 Society of Chemical Industry.

This study was designed to examine carryover effect of dietary lysine (Lys) levels fed during the starter phase on the growth performance of three varieties of Aseel chickens. A total of 378 birds (126 from each variety) derived from a previous experiment, in which birds were distributed according a randomized block design in a 3×3 factorial arrangement, were evaluated from 7-18 weeks of age. Treatments consisted of three varieties of Aseel chicken [(Mianwali (MW), Peshawari (PW) and Lakha (LK)] fed three dietary Lys regimes (high, medium and low) during the starter phase (0-6 weeks). In the present experiment, the performance parameters, carcass traits, and meat chemical composition six replicates of seven birds per treatment were evaluated. The MW variety exhibited higher weight gain and better feed to gain ratio (p<0.05). Previous medium dietary Lys regimen improved weight gain, feed to gain ratio, final weight gain (p≤0.05). Birds previously fed medium dietary Lys showed higher thigh dry matter content (p<0.05), and those previously fed low Lys significantly higher thigh crude protein (CP) content (p<0.05). The highest breast muscle CP % were observed birds previously fed the high Lys regime (p<0.05), those of the MW variety (p<0.05). Higher slaughter weight and carcass weight and yield were obtained in the birds previously fed to medium dietary Lys level (p<0.05), and the MW variety showed overall better carcass traits (p<0.05). It is concluded that medium Lys levels in the starter feed promote subsequent better growth performance and that the MW variety has better carcass traits, it may be used as for rural chicken meat production.
