Miopatias em aves e suas possíveis correlações nas fraturas ósseas e ruptura de pele na linha de abate

Abstract

The consumption of broiler meat has been growing worldwide, one of the reasons for this growth being its great nutritional value. The growing demand for chicken meat has resulted in pressure on breeders, nutritionists and producers to increase bird growth, feed efficiency and muscle yield, especially breasts. Therefore, the present work aimed to identify the main myopathies emerging from a commercial slaughterhouse located in the Northwest region of the state of Paraná and correlate them with the wooden breast (WB) and white stripping (WS) phenomenon. In addition to quantifying the chemical composition and collagen/protein ratio of the skin, muscle and bones of these samples through chemical analyzes of moisture, ash, lipids, proteins and collagen. It is concluded that the causes of partial condemnation of carcasses highlighted by myopathies, with emphasis on the pectoral, being WS and WB, fractures, arthritis and dermatitis are directly associated. The weight of the carcasses is a determining factor in the development of occurrences.
