No effect associated with the levels of vitamin D3 supplementation
and/or sunlight exposure was found during ageing
of the meat (P≥0.15) on the MFI (data not shown) and Warner–
Bratzler shear force values (Table 4). An effect of the duration
of ageing showing the progress of myofibrillar
weakening and a decline in the shear force was observed
(Pb0.01).
