TL;DR: The role of plasma IGF-I during compensatory growth is not clear and must be explained in connection with changes of its binding proteins, which seem to have a permissive effect on growth.

01 May 2003TL;DR: It is now becoming clear that variation in other factors such as the muscle fibre type composition and the buffering capacity of the muscle together with the breed and nutritional status of the animals may also contribute to the observed variation in meat tenderness.
Abstract: Meat quality is a term used to describe a range of attributes of meat. Consumer research suggests that tenderness is a very important element of eating quality and that variations in tenderness affect the decision to repurchase. The present paper highlights recent information on the factors that affect tenderness. While the precise aetiology is not fully understood, a number of factors have been shown to affect tenderness. Of these factors, postmortem factors, particularly temperature, sarcomere length and proteolysis, which affect the conversion of muscle to meat, appear most important. However, it is now becoming clear that variation in other factors such as the muscle fibre type composition and the buffering capacity of the muscle together with the breed and nutritional status of the animals may also contribute to the observed variation in meat tenderness.

TL;DR: The traditional way of using feeding as a quality control tool in the production of meat is re-thinked and the potential of a nutrigenomic approach is introduced as a first step in the development of pro-active quality control systems which fulfil future demands from industry and consumers.

TL;DR: Following a discussion of methods of analysis and their limitations, a series of growth simulations is presented to illustrate why the terms compensatory growth, recovery growth, and catch-up growth should not be used as synonyms.
Abstract: Compensatory growth refers to an animal’s ability to grow extremely rapidly after it has experienced a period of reduced growth. It is also widely held that the growth trajectories of animals showing compensatory growth converge towards those followed by conspecifics that have experienced favorable growth conditions throughout their lives. In other words, it is often assumed that animals undergoing compensatory growth also show some recovery, and thereby exhibit catch-up growth. This belief has resulted in the terms compensatory growth, recovery growth, and catch-up growth being used as synonyms, and has also created some problems with regard to data analysis and interpretation. Following a discussion of methods of analysis and their limitations, a series of growth simulations is presented to illustrate why the terms should not be used as synonyms. The simulations, based upon the assumption that compensatory growth results in a restoration of body composition (using condition index as a surrogate), show that compensatory growth is not always accompanied by a convergence of growth trajectories. Compensatory growth can occur in the absence of catch-up growth, and the simultaneous observation of compensatory growth and a recovery of body mass is a special combination of events. Further, it is possible for growth trajectories to converge even when animals that have experienced a period of reduced growth do not display compensatory growth. Definitions are proposed that distinguish between the terms compensatory growth, recovery growth, and catch-up growth, and guidelines are given relating to the analysis of the results of fish compensatory growth studies.

TL;DR: In summary, feed restriction severely affected growth performance and lipid metabolism in broilers in the early period and might have induced prolonged metabolic programming in chicks and led to adult obesity.
