摘　　要：试验旨在研究妊娠后期及哺乳期母猪饲粮中添加魔芋飞粉对母猪繁殖性能及饲料加工品质的影响。试验选取36头分娩日期相近的3~6胎妊娠后期母猪(长×大),按胎次、体重、膘情随机分成3组,每组12个重复。对照组饲喂基础日粮,2个试验组分别添加2%和4%的魔芋飞粉。试验期为母猪妊娠84 d到仔猪30日龄断奶。结果表明,与对照组相比,母猪妊娠84 d到哺乳期结束饲粮中添加4%魔芋飞粉妊娠后期采食量显著提高(P<0.05),2%组也有提高的趋势(P>0.05)。魔芋飞粉2%和4%组断奶窝重分别提高8.56%和8.62%,3~30日龄窝增重分别提高11.05%和9.22%(P>0.05)。妊娠后期魔芋飞粉2%组母猪便秘率显著减少,便秘评分显著增加(P<0.05);魔芋飞粉4%组便秘率和便秘评分也有改善的趋势(P>0.05)。魔芋飞粉2%和4%组饲料硬度显著提高(P<0.05),含粉率有降低的趋势(P>0.05)。由此可见,母猪妊娠84 d到哺乳期结束饲粮中添加2%和4%魔芋飞粉可提高仔猪断奶窝重和窝增重,明显改善母猪便秘,改善饲料制粒品质。This experiment was conducted to study the effects of adding konjac flour residues to sow diets in late pregnancy and lactation period on sows reproductive performance and feed processing quality.A total of 36 pregnancy sows(Landrace×Yorkshire)with similar farrowing date and 3-6 births were selected and randomly divided into 3 groups according to parity,weight and body condition,resulting in 12 repetitions in each group.Control group was fed a basal diet,two experimental groups were added 2%and 4%konjac flour residues respectively.The experiment was from day 84 of gestation to day 30 after parturition.The results showed that compared with the control group,the sows feed intake of 4%konjac flour residues group in late pregnancy period increased significantly(P<0.05),and the sows feed intake of 2%konjac flour residues group also increased(P>0.05).The pigs weaning weight of 2%and 4%konjac flour residues groups increased by 8.56%and 8.62%,the litter body weight gain of 3-30 days increased by 11.05%and 9.22%(P>0.05).The constipation rate of sows of 2%group of konjac flour residues decreased significantly,constipation score increased significantly(P<0.05),and constipation rate and constipation score of 4%group of konjac flour residues also improved(P>0.05).The feed hardness of 2%and 4%groups of konjac flour residues increased significantly(P<0.05),and the powder content decreased(P>0.05).It was concluded that adding 2%and 4%konjac flour residues to feed during 84 days of gestation to lactation could improve the pigs weaning weight and litter weight gain,also improve sows constipation and feed processing quality.
