Effects of Moriguchizuke residue (MoR) as feed on the growth performance, frequency of water intake of pigs, carcass characteristics and meat quality during fattening were investigated. A total of 48 crossbred pigs (Large White×Landrace×Duroc, six barrows, and six gilts) were housed at a density of four pigs (two barrows and two gilts of similar weight) per pigpen. The pigs were divided into four groups each of which MoR was added to feed at levels of 0% (Control group), 3% (MoR3% group), 6% (MoR6% group) and 12% (MoR12% group). The pigs were fed with experimental diets when the average weight of the pigs in each group reached approximately 50 kg and was terminated when the average weights reached approximately 110 kg. Feed and drinking water were provided ad libitum. For the growth performance examined for twelve pigs in each group, the MoR 12% group showed a significantly higher feed intake than the control group (P<0.05). No significant differences were detected in other growth performance. For the frequency of water intake investigated for eight pigs in each group, the MoR 12% group showed a significantly higher frequency of water intake than the control group (P<0.05). For the carcass characteristics investigated for the following numbers of pigs (control: nine pigs, MoR3% : eleven pigs, MoR 6%, 12% : twelve pigs), carcass length in gilt was significantly shorter in the 6% group than the 3% group (P<0.05), and that in barrow was significantly shorter in the 6% group than the control group (P<0.05). For meat quality examined for three pigs (two barrows, one gilt) in each control, MoR3% and 6% group, no difference was observed. Our results suggested that MoR ≤6% is appropriate when feeding MoR to growing pigs without increasing the frequency of water intake, considering the growth performance, carcass characteristics and meat quality.
