The Growth and Composition of Skeletal Muscle in the Chicken

The Growth and Composition of Skeletal Muscle in the Chicken

“…Details of the stock and its management, and the method of sampling the muscle and preparing the homogenate have been described previously (Simmonds et al, 1964). The homogenate was stored frozen at -20°C.…”

Effect of Glutamic Acid on Broilers Given Submarginal Crude Protein with Adequate Essential Amino Acids Using Feeds High and Low in Potassium

“…accumulate with development of breast meat do so in a manner that is independent of each other and total muscle growth (Simmonds et al, 1964). This independence also occurs with skin, particularly with collagen (Granot et al, 1991).…”

The Growth and Composition of Skeletal Muscle in the Chicken

“…A possible explanation, however, may be a deficiency of glycine, arginine or methionine, which are precursors of creatine and are also essential for muscle growth in chickens. Since the pectoral muscle increased in weight some eight to ten fold during the first week (Simmonds et al, 1964), it is possible that the level in the diet of one or more of these amino acids was insufficient for both this rapid growth and the synthesis of creatine (Fisher et al, 1956).…”

“…

AN INCREASE with age in the con--**• centration of non-protein nitrogen, as well as protein, in the pectoral muscle of the chicken has previously been reported by Dickerson (1960) and by Simmonds et al (1964). However, the nonprotein nitrogen fraction is comprised of a number of substances of differing biological function, such as amino acids, peptides, creatine and purines, and it is to be expected that the pattern of change of these substances will differ.
