Abstract: The present methods and compounds relate to increasing meat tenderness by inducing post-mortem breakdown in muscle tissue. This is achieved by the use of beta-blockers in the pre-mortem period, which results in higher calpastatin levels, and reduced hyperplasia. This is also achieved by the use of agents immediately before slaughter that induce apoptosis in muscle tissue. This is further achieved by administering agents that induce muscle fiber fission.

Abstract: An image analysis (IA) system for scoring characteristics predictive of palatability and yield of a meat animal carcass or cut. The IA system uses an imaging device, a data processing unit for processing image data, and an output device for output of processed data to the user. Also disclosed is a method for using the IA system in predicting palatability, yield, or defect conditions of a meat animal carcass or cut. The results are identified with a particular piece of meat for further grading, sortation and processing.
