- Abstract
This study was to investigate the effects of dietary low protein and food waste (FWS) on growth perfmmance and carcass character of growing-finishing pig. It was divided into two stages: growing and finishing period. A total of 96 commercial black pigs weighting about 47 kg were randomly allocated into three groups: FWS, feeding diet content 15% and 13% cmde protein (CP) dming growing and finishing period (15 ~ 13% CP) and 13 ~ 11% CP. Banows and gilts were kept in separate pens, with 6 pens and 16 heads per pen. The results revealed that at the 28th week of the tlial, body weight of barrow and gilt at FWS, 15 13% CP and 13 ~ 11% CP group were 147 or 142 kg, 148 or 162 kg and 155 or 148 kg, individually. According to market weight of the pigs, the FWS group was about 0.5 ~ 1.4 months later than the others. The total ttiglycerides in blood of FWS was significantly higher than that of 13 - 11% CP and 15 ~ 13% CP. There were no significant differences in carcass characters among those groups.
