Composition of Hypertrophic and Atrophic Muscles in Genetic Muscular Dystrophy of the Chicken

Abstract
Analysis of hypertrophic and atrophic pectoral muscles of chickens with hereditary muscular dystrophy for total N, nonprotein N, non-collagen protein N, and collagen indicated that when considered on the fat-free basis the 2 types of muscle did not differ in composition, except for collagen content. Dystrophic muscle differed in all these components from normal pectoral muscle. The composition of dystrophic muscle suggests that it is a juvenile type of muscle which fails to develop to the normal mature state.
