Data are means for eight animals.
Barrows fed the medium-lysine (0.80%) diet, gilts fed the medium-lysine diet, and gilts fed the low-lysine (0.60%) diet, respectively.
The sensory attribute was scored according to a 5-tier hedonic scale ranging from 1 for the ‘extremely bad’ to 5 for the ‘extremely good’; the greater score indicates the better.
Scored according to a 9-tier hedonic scale ranging from 1 for the ‘extremely dislike’ to 9 for the ‘extremely like.’
T, treatment; B-Med, barrow-medium; G-Med, gilt-medium.
