An interaction between the levels of vitamin D3 supplementation
and sunlight exposure was detected (P=0.03)
for MFI values determined with frozen samples at days 1
and 21 pm (pooled data, Fig. 1), which would reflect fragmentation
extension. Within the animals exposed to sunlight
or under sunshade, no differences were observed (P≥0.15)
due to the levels of vitamin D3 supplementation. However,
higher MFI values were found (P=0.03) in meat from animals
under sunshade compared to those exposed to sunlight
within the V2 group.
