Fat deposition, fatty acid composition and meat quality: A review.
This paper reviews the factors affecting the fatty acid composition of adipose tissue and muscle in pigs, sheep and cattle and shows that a major factor is the total amount of fat. The effects of fatty acid composition on meat quality are also reviewed. Pigs have high levels of polyunsaturated fatty acids (PUFA), including the long chain (C20-22) PUFA in adipose tissue and muscle. The full rang...
متن کاملThe relationship between muscle fiber characteristics, postmortem metabolic rate, and meat quality of pig longissimus dorsi muscle.
The aim of this study was to investigate the histochemical parameters of muscle fibers, and to estimate the correlation of muscle fiber characteristic to postmortem metabolic rate and meat quality traits in pigs. A total of 231 crossbred pigs were evaluated. Samples of the longissimus dorsi muscle were taken to evaluate the histochemical characteristics, postmortem metabolic rate and meat quali...
متن کاملOf bears, frogs, meat, mice and men: complexity of factors affecting skeletal muscle mass and fat.
Extreme loss of skeletal muscle mass (atrophy) occurs in human muscles that are not used. In striking contrast, skeletal muscles do not rapidly waste away in hibernating mammals such as bears, or aestivating frogs, subjected to many months of inactivity and starvation. What factors regulate skeletal muscle mass and what mechanisms protect against muscle atrophy in some species? Severe atrophy a...
متن کاملSignificance of Muscle Fiber Types in Development of Muscle and Meat Quality
Muscle fibers constitute the essential structure responsible for the propulsive activity. They contain the enzymes required for the energy utilization and the different proteins needed for the contraction. Their contractile and metabolic properties take place during the foetal and neonatal periods and are controlled by several growth factors. Muscles also contain proteolytic enzymes responsible...
