Document Summary
Wild versus domestic pigs wild boars are not bred for their genetics so they have a smaller number of fibers. Stimulus that will increase the length of the muscle fibers growth in length is induced by hypertrophy. Achieved through the addition of the sarcomeres (the structural and functional unit of the muscle) Nutritional status and hormones will affect protein turnover i. e. the ratio of synthesis to degradation (a combination of protein synthesis and degradation and the amount of time it takes for each) Feed efficiency requires a lower protein turnover. Lean accretion of average daily gain requires a lower protein turnover there is a direct link between reactive oxygen species to protein turnover. Degradation selectively will remove bad and damaged proteins. Three proteolytic systems in a muscle that are key to protein degradation contributes to muscle fiber atrophy. Synthesis and degradation are under independent control require essential amino acids.
