A cooperative regional research study using 194 sows, from which data were collected from 381 litters, was conducted at 3 research stations to determine the effects of added psyllium (a concentrated fiber source) or soybean hulls to gestation diets on reproductive performance of sows and preweaning performance of their pigs. Primiparous and multiparous sows were allotted to the 3 treatments of control (corn and soybean meal-based), 0.30% psyllium, or 20% soybean hulls. Sows fed the control and 0.30% psyllium diets were provided 1.82 kg/d, and sows fed the 20% soybean hulls diet were provided 2.0 kg/d to equalize ME, Lys, Ca, P, and vitamin and trace mineral intake. Treatments 1 to 3 had 130, 130, and 121 litters per treatment from 64, 64, and 63 sows, respectively. Gestating sows fed psyllium had a greater (P < 0.01 to 0.10) d 110 gestation, farrowing, weaning, and 17 d postpartum BW and gestation ADG compared with sows fed soybean hulls. Sows fed psyllium also had a greater (P < 0.10 and 0.08) d 110 gestation BW and gestation ADG than the control sows. Sows fed soybean hulls had a reduced (P < 0.06) farrowing BW compared with the control sows. Sows fed psyllium weaned lighter (P < 0.09) pigs than sows fed the control diet. Litter size was not affected (P > 0.10) by diet. Sows fed psyllium had a reduced (P < 0.03) feed intake compared with sows fed soybean hulls for d 5 to 7 postpartum, and sows fed the control diet were intermediate. Fecal scores (1 to 5 with 1 = dry and 5 = watery) were greater (P < 0.001) and DM content was less (P < 0.001 to 0.01) in the feces of sows fed soybean hulls compared with sows fed psyllium or the control diet on d 112 of gestation and d 4 postpartum. Fecal scores were greater (P < 0.10) and fecal DM content was less (P < 0.02) in sows fed psyllium compared with sows fed the control diet only on d 4 postpartum. In summary, sows fed soybean hulls during gestation had reduced BW compared with sows fed the control diets. In contrast, sows fed psyllium had an increased BW.
一项合作的区域研究在3个研究站开展，使用了194头母猪，收集了来自381窝的数据，以确定在妊娠日粮中添加车前籽壳粉（一种浓缩纤维来源）或大豆皮对母猪繁殖性能及其仔猪断奶前性能的影响。初产和经产母猪被分配到3种处理组，分别为对照组（基于玉米和豆粕）、0.30%车前籽壳粉组或20%大豆皮组。饲喂对照组和0.30%车前籽壳粉日粮的母猪每天提供1.82千克饲料，饲喂20%大豆皮日粮的母猪每天提供2.0千克饲料，以使代谢能、赖氨酸、钙、磷以及维生素和微量矿物质的摄入量相等。处理1至3每组分别有64、64和63头母猪，每处理组分别有130、130和121窝仔猪。与饲喂大豆皮的母猪相比，饲喂车前籽壳粉的妊娠母猪在妊娠110天、产仔、断奶时以及产后17天的体重更大（P<0.01至0.10），妊娠平均日增重也更高。与对照组母猪相比，饲喂车前籽壳粉的母猪在妊娠110天的体重和妊娠平均日增重也更大（P<0.10和0.08）。与对照组母猪相比，饲喂大豆皮的母猪产仔时体重降低（P<0.06）。与饲喂对照日粮的母猪相比，饲喂车前籽壳粉的母猪所产仔猪断奶时体重更轻（P<0.09）。日粮对产仔数没有影响（P>0.10）。与饲喂大豆皮的母猪相比，饲喂车前籽壳粉的母猪在产后第5至7天的采食量降低（P<0.03），饲喂对照日粮的母猪采食量介于两者之间。在妊娠112天和产后第4天，与饲喂车前籽壳粉或对照日粮的母猪相比，饲喂大豆皮的母猪粪便评分更高（1至5分，1分表示干燥，5分表示水样便）（P<0.001），粪便干物质含量更低（P<0.001至0.01）。仅在产后第4天，与饲喂对照日粮的母猪相比，饲喂车前籽壳粉的母猪粪便评分更高（P<0.10），粪便干物质含量更低（P<0.02）。总之，与饲喂对照日粮的母猪相比，妊娠期间饲喂大豆皮的母猪体重降低。相比之下，饲喂车前籽壳粉的母猪体重增加。
