1. Histological and histochemical profiles of Musculus pectoralis (PT, type IIB fibres), M. iliotibialis lateralis (ITL, types IIA + IIB fibres) and M. puboischiofemoralis pars medialis (PIF, type I fibres) were compared in carbon dioxide (37%, 70 s) and electrically (14 V, 5 s) stunned male chickens. 2. Muscle materials were taken at 0, 4 and 24 h from carcases dressed and cooled with ice-water mixture for 30 min. Glycogen and fat contents, and adenosine triphosphatase and reduced nicotinamide… 
Comparison of blood variables, fiber intensity, and muscle metabolites in hot-boned muscles from electrical- and gas-stunned broilers.
TLDR
It is indicated that G40% was potentially a superior stunning variable and no essential difference in energy metabolism was found in broilers stunned with ES and GS when ES was based on low current and high frequency and GS wasbased on hypercapnic moderate oxygenation.
Post-mortem analysis in three muscles of red neck ostrich (Struthio camelus massaicus).
TLDR
The immunohistochemical results revealed that in this species calpain/calpastatin system was localized in various parts of the muscles, although µ-calpain and m-Calpain totally disappeared at 4 days post-mortem.
BIOCHEMICAL CHARACTERIZATION OF LEG AND BREAST MUSCLE OF QUAIL
TLDR
Findings suggest that as the pH of meat falls, tenderness decreases and Glycogen content and amount of lactic acid of the muscle is also in agreement with the finding of pH.
Histochemical characteristic of biceps femoris of Rhode Island Red and Greenleg Partridge hens
TLDR
The histochemical results from this experiment have shown that genotype affected the percentage of the muscle fibres, which can suggest an effect of higher mobile activity of Rl 1 on their muscle physiology.
Recent concerns about stunning and slaughter.
Improved animal welfare, the right technology and increased business.

Breed differences in the histochemical properties of the M. pubo-ischio-femoralis pars medialis myofibre of domestic cocks.
TLDR
It was concluded that PIF muscle performed an important function in supporting the body weight and maintaining posture and made an effective response to the different body weights.
Characterization of Rigor Mortis Development in Four Broiler Muscles
TLDR
The results led to the conclusions that rigor mortis development in broiler muscles was more rapid in red fibers than in white fibers, was slowed by chilling only inred fibers, and could not be accurately predicted from biochemical changes.
The relationship between muscle growth and the growth of different fiber types in the chicken.
TLDR
A relationship of muscle growth to fiber growth was investigated histochemically and allometrically in the chicken from 1 to 35 wk of age and found greatest growth occurred in Type IIB fibers of hindlimb muscles.
Distribution of myofiber types in thigh muscles of chickens
TLDR
The spatial distribution of myofiber types within individual muscles can account for the various locomotory and postural requirements of the thigh.
Effects of parent Shamo cocks on the histochemical properties of M. iliotibialis lateralis and M. supracoracoideus on their crossbred broilers.
TLDR
The histochemical features of fibre type seemed to develop with bird age, particularly subsarcolemmal accumulation of formazan granules (indicating high NADH-DH activity) in Type IIR fibres in the crossbred cockerels.
The effect of oestrus behaviour on muscle glycogen concentration and dark-cutting in beef heifers.
Breed differences in the histochemical properties of the M. iliotibialis lateralis myofibre of domestic cocks.
TLDR
It was concluded that the muscle characteristics of various breeds were based not only on the fibre type composition, but also the different activities of oxidative enzyme in every type.
Comparative studies on the histochemical properties of M. iliotibialis lateralis from Kumamoto Cochin crossbred roaster and broiler chickens.
TLDR
Compared with normal broilers, marked differences in histochemical properties and meat quality between KC roasters and broilers were indicated.
EFFECT OF ELECTRICAL STUNNING ON POSTMORTEM BIOCHEMICAL CHANGES AND TENDERNESS IN BROILER BREAST MUSCLE
TLDR
It was concluded that electrical stunning inhibited the rapid breakdown of ATP, CP and glycogen, and thus delayed the onset of rigor until after spin-chill by which time muscle temperature reached 4°C, resulting in improved meat tenderness.
