The effects of adding inulin to low- or high-fat diet on the metabolic status and nutrient digestibility in gestating sows and the neonatal traits of their offspring were examined. Sixty sows were allocated to a 2 × 2 factorial treatment design with levels of inulin (0% or 1.5%) and fat (0% or 5%) addition as the fixed factors during gestation. Inulin supplementation resulted in the following: improved serum lipid profiles, insulin resistance, and glucose tolerance, which were adversely impacted by fat addition; increased serum butyrate concentration throughout gestation and propionate concentration on day 60 of gestation when given with a high-fat diet; enhanced fecal bile acid excretion in a high-fat diet; lowered ether extract (EE) digestibility and increased calcium digestibility in the sow; and decreased BMI and carcass EE content in neonatal piglets. The beneficial effects of inulin were particularly marked when it was combined with a high-fat diet.

研究了在低脂或高脂饮食中添加菊粉对妊娠母猪的代谢状态和营养消化率及其后代的新生儿性状的影响。60头母猪被分配到2×2析因治疗设计中，其中菊粉（0％或1.5％）和脂肪（0％或5％）的添加水平是妊娠期间的固定因素。补充菊粉的结果如下：血清脂质，胰岛素抵抗和葡萄糖耐量的改善，这受到脂肪添加的不利影响；使用高脂饮食时，整个妊娠期的血清丁酸浓度升高，而在妊娠第60天时的丙酸盐浓度升高；高脂饮食中粪便胆汁酸的排泄增加；降低母猪的乙醚提取物（EE）消化率并提高钙的消化率；并降低了新生仔猪的体重指数和体EE含量。菊粉与高脂饮食搭配使用时，其有益效果尤为明显。
