Extract

Mixing of cattle prior to slaughter which results in aggressive activity (Mohan Raj et al 1992) leads to glycogen depletion pre-slaughter and subsequently meat with a higher ultimate pH (pHu). Purchas et al (1990) reported a quadratic relationship between pHu and tenderness with highest shear force values recorded between pHu 5.8 to 6.2. The aim of this study was to determine the effect of fasting and mixing of steers prior to slaughter on the meat eating quality of longissimus dorsi (LD) muscle.
