	abstract = {There is little information available on the muscle biology of deer and   how this affects meat quality. The reported effects of the calcium dependent   protease system (calpains and their inhibitor calpastatin) on protein turnover   in vivo and myofibrillar structure posts mortem suggest it may have a pivotal   role in regulating muscle growth and meat tenderisation. This study   examines inter-muscle variation in the calpain system under two  physiological   conditions in red deer and its relation to meat tenderness. Nine muscle   samples from 3 stags in rut (IR) and 3 out of rut (OR), were processed for   calpain and calpastatin analysis within 20 minutes of slaughter. Tenderness   of aged muscles was determined by measurement of ultimate shear force.   The majority of the inter-muscle differences in the calpain system were   associated with calpastatin activity. A positive relationship between muscle   calpastatin levels and meat ultimate shear force was found.   },
