Název v původním jazyce

The influence of ante-mortem treatment on beef texture.

Popis výsledku v původním jazyce

Longissimus lumborum et thoracis muscles from 150 cattle comprising Czech Pied breed bulls and cows were used to investigate the relationship between pH value and beef tenderness as influenced by housing before slaughter and by hanging mode of carcasses.The pH value was measured in the loin at the end of slaughter line (pH0) and after cooling of carcasses (pH24, pH48). The texture of raw meat was measured 72 hours post mortem by the Warner-Bratzler shear method; the shear force was related to pH. Curvilinear relationship with coefficient of correlation r=0.64 (P<0.05) for bulls individually housed and r=0.83 for bulls housed in groups between the shear force and the pH value 24 h p.m. was found with maximal shear force (the most tough meat) in the range of pH24 from 6.2 to 6.4. The lower correlation (r=0.72 and r=0.54) between pH24 and meat tenderness was found in the case of cows individually housed and housed in groups respectively. No significant relation was found between texture
