Effect of lairage time (0h, 3h, 6h or 12h) on glycogen content and meat quality parameters in suckling lambs
The effect of slaughter at arrival (L0) or after 3 (L3), 6 (L6), 12 (L12) h of lairage on carcass and meat quality of suckling lambs has been studied. Lairage time had a slight effect on carcass quality traits, but most of the meat quality parameters at 24. h post mortem were affected. Weight losses increased and glycogen content of liver and longissimus muscle decreased as lairage time increased. Longissimus muscle from L3 lambs had the highest pH, shear force and toughness and the lowest b* and C* values, at 24. h post mortem. L3 and L6 had the higher proportion of expelled juice, or low water holding capacity (WHC), at 24. h post mortem. Texture parameters and WHC were similar among groups after 5. days of storage. Despite the fact that the effects of lairage time on meat quality disappears after storage, from the point of view of weight losses the slaughter of suckling lambs at arrival is recommended. © 2013 Elsevier Ltd.
