a,bValues within a row with different superscript letters are significantly different (P < 0.05). Data are presented as mean ± SEM, n = 6.
Cont.: inorganic minerals (sulfates salts), Mix: 50% inorganic + 50% glycinates.
Glycinates minerals were used in both M-OTM and L-OTM, and inclusion level was reduced to 70 and 50%, respectively.
