[Protein synthesis in vivo in muscles of the growing lamb]. 1977

M Ferrara, and M Arnal, and G Fauconneau

The relationship between incorporation of intravenously injected 14C lysine and specific radio-activity of precursor was used to estimate protein synthesis in muscle of growing lambs. The rate of protein synthesis per unit of muscle weight in Supraspinatus and Extensor digitorum longus decreased strongly from one week of age to puberty (10 weeks); afterwards it decreased in supraspinatus and increased slightly in Extensor digitorum longus. The rate of protein synthesis increase in muscle protein weight was constant during the whole experiment (1 week-16 weeks). In preruminant Lambs )1 week-5 weeks) the rate of protein synthesis per unit of muscle weight decreased; however, due to the increase in muscle weight, the rate of protein synthesis in whole muscle remained relatively constant. In order Lambs the rate of protein synthesis in whole muscle decreased. The turnover time of protein increased with age. These results give some explanation on muscular development of Lambs.

D000367	Age Factors	Age as a constituent element or influence contributing to the production of a result. It may be applicable to the cause or the effect of a circumstance. It is used with human or animal concepts but should be differentiated from AGING, a physiological process, and TIME FACTORS which refers only to the passage of time.
