The study of any pre-slaughter stressor requires good control and standardisation of the post-slaughter environment especially rigor temperature, which has profound effects it can have on key traits like tenderness and water-holding capacity (Bendall, 1973).
With the implementation of eating quality assurance systems underpinned by critical control point methodology (eg Meat Standards Australia (MSA), Polkinghorne, 2006), standardisation of the post-slaughter environment has been achieved significantly better than in the past.
However, whilst good progress has been made, these models for predicting meat quality also enable us to estimate how much we do not know about the process.
For example, (Warner, Ferguson, Cottrell, & Knee, 2007) concluded that the negative effects of acute pre-slaughter stress in beef cattle on eating quality, induced by the use of electric goads, could not be accounted for in the MSA model for predicting the eating quality of beef.
Similarly, the model did not account for the variation observed between eight slaughter groups of cattle in consumer panel score and change in shear force in a study comparing different marketing methods by Ferguson, Warner, Walker, and Knee (2007) (see Fig. 1).
Given this, there has been an increased emphasis on quantifying the impact of pre-slaughter stress and exploring strategies for mitigating any stress-mediated losses in meat yield and quality.
The purpose of this paper is to review the current knowledge with regard to the impact of pre-slaughter stress on ruminant meat quality.
