The aim of this study was to evaluate the effects of pre slaughter lairage time and temperament on glycogen content. Fourteen Hereford steers fed on pasture were assigned to two treatments (T) according to lairage time: 3 hours (T1, n = 7) and 12 hours (T2, n = 7). Individual temperament was assessed using crush score and flight speed. Muscle samples were extracted from Longissimus thoracis et lumborum (LM) muscles 45 minutes post mortem, to determine glycogen content. To evaluate the effect of lairage time and temperament on glycogen content, analysis of variance was used fitting a general linear model including the fixed effects of lairage time, CS, and FS in classes. Adjusted means were compared by the Tukey test and the results were considered statistically significant when P < 0.05. Muscle glycogen was lower (P < 0.05) in T1suggesting a higher level of stress in this treatment. Furthermore, more excitable animals had lower glycogen content (P < 0.05). Considering that glycogen can affect other meat quality traits, it is important to be alert to situations where the glycogen content is reduced. |

ABSTRACT
Grapefruits are widely recognized by their extreme sensitivity to develop chilling injury (CI) during postharvest storage at low temperature. Moreover, many cultivars and mutants of grapefruits exhibit important differences in both external and internal coloration, from yellow to deep red, due to a distinctive accumulation of the red carotene lycopene. Thus, in this study the genetic variability in external peel coloration of grapefruits has been used to examine the potential relationship between carotenoid content and composition, and susceptibility to CI. CI increased progressively after 2 weeks storage at 2°C in fruit of the yellow grapefruit ?Marsh? (M) but in the fruits of red cultivar ?Star Ruby? (SR) CI symptoms were exclusively restricted to the yellow areas of the peel. Thus, CI was absent in red peel tissue, even after prolonged cold storage, in which lycopene content was about 14-times higher than in yellow tissue. In addition, SR grapefruits growing under shaded conditions developed an intense external red coloration and accumulated large amount of
lycopene, and were also highly resistant to CI upon subsequent postharvest cold storage. To further explore the mechanisms involved in the resistance to CI induced by lycopene, total antioxidant activity was determined in yellow and red peel tissue of grapefruit, and the potential relationship between carotenoids and the development of CI is discussed. |
