“…In addition, an effect of gender, stress, genetics, maturity of collagen in muscle tissue was evaluated; however, causes leading to this defect still are not fully revealed. Finally, the defect was called a «disease of thin piglets» as this defect appeared in large quantities in enterprises that turned to raising pigs with backfat depth less than 14 mm [19,20,21]. In more recent studies of pork muscles, an association was found between emergence of defects of the «destructured meat» type and the prevalence of type 2B fibers [12,13].…”

“…An interest to n allele was quickly recognized in terms of its influence on meat quality deterioration (a risk of the PSE development). Since 1993, the use of the molecular test has allowed recognizing animals with Nn and NN genotypes as halothane-insensitive pigs and assessing an impact of n allele on productivity of animals and meat quality [21,35,36,37]. This led to the fact that animals -carriers of ryr1 gene with nn alleles were practically excluded from meat production.…”

This review paper is devoted to myopathy of slaughter animals and poultry, and examines a relationship between fast growth of muscle tissue in hybrid pigs, broiler chickens and turkey, and high frequency of detection of spontaneous or idiopathic myopathies. The development of myopathy reduces consumer and technological properties of meat, and leads to emergence of different pathological conditions (PSE or RSE meat, «destructured meat», «white» or «green» meat, punctate hemorrhage, «wooden breast» and others). Two types of myopathic conditions are examined: myopathies caused by stress in animals and nutritional myopathies, which contribution to meat quality deterioration seems to be determinative. It is shown that the basis of the mechanism of the myopathy development is the mechanism of the successive changes in muscle tissue: damage of cell membranes and release of mitochondrial calcium, which causes hypercontraction, dystrophic changes, atrophy and necrosis of muscle fibers. To alleviate the damaging effect of two types of myopathies, different substances-adaptogens (selenium, vitamin E, flavonoids and others) can be used. It is stated that the requirements of animals in adaptogens change with an increase in the indicators of their productivity. UDC 636.4.084
