To investigate the effect of dietary supplementation with a fermented mixture of bean dregs and wheat bran (FBW) on sow performance. FBW was given to sows during late gestation and lactation; in total, 24 sows were randomly assigned to 4 groups (control diet; 3% FBW diet; 6% FBW diet; 9% FBW diet, n = 6). The weight ratio of bean dregs (wet) to wheat bran was 4:6. Sows were fed different diets from 85 d of gestation until weaning. The results showed that supplementation with FBW increased average daily feed intake (ADFI) during lactation ( < 0.05). FBW supplementation also increased litter weight and milk yield ( < 0.05). The contents of in the feces of the treatment groups were significantly reduced by FBW supplementation ( < 0.01). FBW supplementation significantly improved the fecal morphology ( < 0.05), alleviating sows' constipation. In conclusion, FBW could increase the ADFI, improve lactation and piglet litter weight in sows and reduce the pathogenic bacterial content in sow feces and constipation.
为研究日粮中添加豆粕和麦麸发酵混合物（FBW）对母猪生产性能的影响。在妊娠后期和哺乳期给母猪饲喂FBW；总共24头母猪被随机分为4组（对照日粮组；3% FBW日粮组；6% FBW日粮组；9% FBW日粮组，每组n = 6）。豆粕（湿）与麦麸的重量比为4:6。从妊娠85天到断奶，给母猪饲喂不同日粮。结果表明，添加FBW可提高哺乳期的平均日采食量（ADFI）（P<0.05）。添加FBW还增加了仔猪窝重和产奶量（P<0.05）。FBW添加显著降低了各处理组粪便中的 含量（P<0.01）。FBW添加显著改善了粪便形态（P<0.05），缓解了母猪便秘。总之，FBW可提高母猪的ADFI，改善泌乳性能和仔猪窝重，并降低母猪粪便中的病原菌含量及便秘情况。
