Características do crescimento animal, do tecido muscular esquelético e da maciez da carne de bovinos nelore e mestiços no modelo biológico superprecoce

Abstract

The present work was lead with objective to study the standard of growth of the tissue muscular by characterization of the muscular fibers during the animal development and the consequences in the final meat tenderness of bovines of Nellore breed. Twenty animals of Nellore breed had been feedlot in the superprecoce' biological model. During the growth samples were collected by biopsy in animals to analyze the composition of muscular tissue in living animal and the influence in the meat quality on the postmortem. The area and diameter of fibers SO, FOG and FG (slow oxidative, fast oxidative-glicolitic and fast glicolitic), had showed correlations (P0,05 respectively). In this way we can infer which size of muscular fiber can influence negatively in meat quality characteristics of, tenderness especially.

Este trabalho foi conduzido com o objetivo de estudar o padrão de crescimento do tecido muscular por caracterização das fibras musculares durante o desenvolvimento animal e suas conseqüências na maciez final da carne de bovinos da raça Nelore. Foram utilizados 20 animais da raça Nelore criados no modelo biológico superprecoce. Durante o crescimento foi realizada biopsia nos animais para analisar a composição do tecido muscular no animal in vivo e sua influência na qualidade da carne postmortem. A área e diâmetro das fibras SO, FOG e FG (fibras oxidativas, oxidativas-glicolíticas e glicolíticas) apresentaram correlações (P0,05 respectivamente). Desta maneira podemos inferir que o tamanho da fibra muscular pode influenciar negativamente nas características de qualidade de carne, em especial a maciez.
