A total of 150 weanling pigs [(Yorkshire × Landrace) × Duroc] with an average BW of 7.22 ± 0.80 kg (21 d of age) were used in a 28-d trial to determine the effects of dietary fructan and mannan oligosaccharides on growth performance, nutrient digestibility, blood profile, and diarrhea score in weanling pigs. Pigs were allotted randomly to 1 of 5 dietary treatments: 1) negative control (NC), basal diet; 2) positive control (PC), NC + 0.01% apramycin (165 mg/kg); 3) NC + 0.1% fructan (FC); 4) NC + 0.1% mannan oligosaccharide source (MO); and 5) NC + 0.05% fructan + 0.05% mannan oligosaccharide source (FM). There were 3 replications per treatment with 10 pigs per pen (5 barrows and 5 gilts). From d 0 to 14, ADG and ADFI of pigs fed the PC, MO, and FM diets were greater (P < 0.05) than pigs fed the NC diet. From d 15 to 28, there were no differences (P > 0.05) in ADG, ADFI, and G:F. During the overall period (d 0 to 28), pigs fed the MO diet had a greater ADG than pigs fed the NC diet (P < 0.05). Pigs fed the PC and MO diets increased ADFI (P < 0.05) compared with pigs fed the NC diet. However, no differences were detected among dietary treatments in G:F during the overall experimental period. On d 14, the apparent total tract digestibility (ATTD) of DM and N in pigs fed the PC, MO, and FM diets was greater (P < 0.05) than pigs fed the NC diet. The ATTD of DM increased (P < 0.05) in pigs fed the MO and FM diets compared with pigs fed the FC diet. However, at the end of the experiment, pigs fed the FM diet had a greater (P < 0.05) ATTD of DM compared with pigs fed the NC diet. Additionally, there were no differences in IgG, red blood cells, white blood cells, and lymphocyte counts among dietary treatments on d 0, 14, or 28. The diarrhea score in pigs fed the MO diet was reduced (P < 0.05) compared with pigs fed the NC diet. In conclusion, mannan oligosaccharides have a beneficial effect on growth performance and nutrient digestibility in weanling pigs. Furthermore, mannan oligosaccharides can decrease diarrhea score in weanling pigs.
共有 150 头断奶仔猪 [(约克夏 × 长白) × 杜洛克]，平均体重为 7.22 ± 0.80 kg(21 日龄)，用于为期 28 天的试验，以确定日粮果聚糖和甘露寡糖对断奶仔猪生长性能、养分消化率、血液指标和腹泻评分的影响。将仔猪随机分配到 5 种日粮处理之一：1) 阴性对照 (NC)，基础日粮;2) 阳性对照 (PC)，NC + 0.01% 安普霉素 (165 mg/kg);3) NC + 0.1% 果聚糖 (FC);4) NC + 0.1% 甘露寡糖源 (MO);5) NC + 0.05% 果聚糖+0.05% 甘露寡糖源 (FM)。每种处理有 3 个重复，每个重复 10 头猪(每栏 5 头公猪和 5 头母猪)。从第 0 天到第 14 天，饲喂 PC、MO 和 FM 日粮的仔猪的 ADG 和 ADFI 均高于饲喂 NC 日粮的仔猪(P < 0.05)。从第 15 天到第 28 天，ADG、ADFI 和 G:F 无差异(P > 0.05)。在整个试验期(第 0 天至第 28 天)，饲喂 MO 日粮的仔猪 ADG 高于饲喂 NC 日粮的仔猪(P < 0.05)。饲喂 PC 和 MO 日粮的仔猪 ADFI 增加(P < 0.05)，而饲喂 NC 日粮的仔猪则没有增加。然而，在整个试验期间，日粮处理对 G:F 没有影响。在第 14 天，饲喂 PC、MO 和 FM 日粮的仔猪的 DM 和 N 的表观全肠道消化率 (ATTD)高于饲喂 NC 日粮的仔猪(P < 0.05)。与饲喂 FC 日粮的仔猪相比，饲喂 MO 和 FM 日粮的仔猪的 DM ATTD 增加(P < 0.05)。然而，在试验结束时，饲喂 FM 日粮的仔猪的 DM ATTD 高于饲喂 NC 日粮的仔猪。此外，在第 0 天、第 14 天或第 28 天，日粮处理对 IgG、红细胞、白细胞和淋巴细胞计数没有影响。饲喂 MO 日粮的仔猪腹泻评分降低(P < 0.05)，而饲喂 NC 日粮的仔猪腹泻评分升高。综上所述，甘露寡糖对断奶仔猪的生长性能和养分消化率有有益影响。此外，甘露寡糖可以降低断奶仔猪的腹泻评分。
