Abstract

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.
