Effect of rest period in lairage on meat quality of simmental bulls and heifers

In recent years a major problem in the beef chain production, which can lead to economic losses has been a frequent occurrence of dark, firm, dry beef. Consumers prefer a light pink to bright red colour and they will strongly reject dark coloured beef, believing that it is from old or sick cattle or that it is badly contaminated. The aim of this research was to examine the effect of rest period in lairage on the quality of Simmental bulls and heifers. The study was conducted on 400 cattle (200 bulls and 200 heifers), aged from 13 to 16 months. The cattle were divided in two groups ; the first group rested for 18 hours in lairage prior to slaughter, while the second group (unrested) was taken to slaughterline immediately after being unloaded. Quality indicators pH, EC and meat colour values were measured 24 hours post-mortem. Heifers had significantly lower muscle pH24, EC value and higher L* and b* value, while bulls had significantly higher parametars pH24 and EC value (P<0.001). Bulls rested in lairage had significantly poorer pH24, L*, b* and h* value compared with unrested bulls, while rested heifers had significantly better pH24, L* and h* value, compared with unrested heifers (P<0.05). Our results indicate that the rest period in heifers could have a beneficial effect on beef quality, while in bulls rest period is not recommended.
