Abstract
The objective was to conduct a systematic review to evaluate the effects of dietary supplementation with beta-adrenergic agonists on calpains and calpastatin activity in bovine muscle and changes in meat tenderness. A survey was conducted in June 2019 on Science Direct, Web of Science, Scopus, PubMed and Capes Periodicals, using four keyword combinations: agonist and calpain and cattle; agonist and calpain and bovine; agonist and calpain and heifers; agonist and calpain and steers. Thirteen studies were selected, 54% concluded that supplementation with beta-adrenergic agonists increases calpastatin activity, 23% observed increase in their gene expression and 23% reported no effect on activity or expression of this enzyme. Nine studies evaluated the influence of beta-adrenergic agonists supplementation on meat texture and all found an increase in shear force values. There is strong evidence that beta-adrenergic agonists may increase calpastatin activity in the muscle, causing damage to meat tenderness.
