Abstract(s)
The objective of this work was to use meta-analysis to estimate the effect size
of the electrical stimulation on beef tenderness through the study of the measurements of
shear force. Eight independent studies were used based on comparison of shear force
measurements on the Longissimus dorsi and Longissimus lumborum in cattle carcasses
subject to electrical stimulation and unstimulated carcasses. For each study, the mean effect
size and standard error was calculated in order to apply a random-effects meta-analysis
model. The meta-analysis demonstrated that the electrical stimulation on beef carcasses
decreases the values of shear-force of meat by an average of 1.34 kgf. Thus, this study
confirmed the positive effect of the electrical stimulation on the beef meat tenderness.
However, the effect size displayed high variation among studies which can be attributed to
differences in their experimental conditions.
