چکیده

This paper investigates the nutritional regulation of glycogen concentration in skeletal muscle of sheep and cattle following exercise, with particular emphasis on a comparison between these species. Four experiments are summarized, indicating a clear relationship between metabolizable energy (ME) intake and rate of muscle glycogen repletion following exercise. Sensitivity to ME intake appeared to differ between species, with sheep demonstrating higher rates of glycogen repletion on lower levels of ME intake than cattle. Roughage diets appeared to produce maximal rates of muscle glycogen repletion in sheep. The use of a glycerol and propylene glycol supplement to enhance muscle glycogen repletion following exercise had marginal success as compared with normal rations, but the efficiency of conversion of the ME of the supplement into muscle glycogen was far higher.

The effect of nutrition on muscle pH decline and ultimate pH post-mortem in sheep and cattle

This paper reviews the effect of nutrition on rate of post–mortem pH decline, pH change after electrical stimulation (delta pH) and ultimate pH in skeletal muscle of sheep and cattle. The importance of muscle glycogen concentration as a determinant of ultimate pH, delta pH and rate of pH decline post–mortem is illustrated. As delta pH and rate of pH decline are increased by high muscle glycogen...

The regulation by nutrition of glycogen in the muscle of ruminants

This paper discusses recent work by the authors which has investigated the nutritional regulation of glycogen concentration in skeletal muscle of sheep and cattle. Several experiments are summarised which show a clear relationship between the level of glycogen in muscle and the intake of metabolisable energy. This translates into strong seasonal effects on muscle glycogen in pasture fed cattle....

Glycogen Metabolism and Meat Quality

pHu of meat is an index of high quality since it is associated with a bright red colour, increased tenderness, increased flavour and increased keeping and cooking qualities. Few studies have examined glycogen level and/or metabolism directly in meat producing animals. Instead most studies have examined the pHu of meat as an index of glycogen metabolism. This is unfortunate since the pHu of meat...

McArdle Disease and Exercise Physiology

McArdle disease (glycogen storage disease Type V; MD) is a metabolic myopathy caused by a deficiency in muscle glycogen phosphorylase. Since muscle glycogen is an important fuel for muscle during exercise, this inborn error of metabolism provides a model for understanding the role of glycogen in muscle function and the compensatory adaptations that occur in response to impaired glycogenolysis. ...
