A total of 150 21-day-old weaned piglets [(Yorkshire × Landrace) × Duroc] were randomly assigned to 3 groups (CON, TRT1, TRT2) to evaluate the effects of dietary supplementation of probiotic, paraprobiotic, and hydrolyzed yeast mixture (PPY) on growth performance, nutrient digestibility, fecal bacterial counts, fecal calprotectin contents, and diarrhea rate in a 42-day experiment (phase 1: days 1-14; phase 2: days 15-42). There were 10 replicate pens per treatment with 5 pigs per pen (three gilts and two barrows). Pigs in CON were only provided with a basal diet. Pigs in TRT1 were provided with a basal diet + 3000 mg/kg zinc oxide during phase 1 and a basal diet during phase 2. Pigs in TRT2 were provided with a basal diet + 200 mg/kg probiotic (Saccharomyces cerevisiae boulardii) + 800 mg/kg paraprobiotic (inactivated yeast strains of Saccharomyces cerevisiae and Cyberlindnera jadinii) + 10 g/kg hydrolyzed yeast mixture during phase 1, and a basal diet + 100 mg/kg probiotic + 400 mg/kg paraprobiotic mixture during phase 2. Pigs in TRT1 and TRT2 were significantly heavier at day 14 and 42 than CON pigs. Growth rate during days 1-14, 15-42, and 1-42 and feed efficiency during days 1-14 were similarly affected by treatment while feed efficiency was significantly higher for TRT2 pigs between 15-42 and 1-42 days. Moreover, nitrogen and energy digestibility in both TRT1 and TRT2 were higher than that in CON. During experimental periods, diarrhea rate in TRT1 and TRT2 was lower than that in CON. Therefore, we demonstrated that PPY supplementation had comparable effects as ZnO in improving growth performance and nutrient digestibility as well as ameliorating post-weaning diarrhea in weaned piglets.
150 头 21 日龄断奶仔猪[(约克夏×长白)×杜洛克]被随机分为 3 组(CON、TRT1、TRT2)，以评估日粮中添加益生菌、副益生菌和酵母水解物混合物(PPY)对生长性能、养分消化率、粪便细菌计数、粪便钙卫蛋白含量和腹泻率的影响，试验为期 42 天(第 1 阶段：第 1-14 天;第 2 阶段：第 15-42 天)。每个处理组有 10 个重复栏，每个栏有 5 头猪(3 头母猪和 2 头公猪)。CON 组的猪只提供基础日粮。TRT1 组的猪在第 1 阶段提供基础日粮+3000mg/kg 氧化锌，在第 2 阶段提供基础日粮。TRT2 组的猪在第 1 阶段提供基础日粮+200mg/kg 益生菌(Saccharomyces cerevisiae boulardii)+800mg/kg 副益生菌(灭活的酿酒酵母和 Cyberlindnera jadinii 酵母菌株)+10g/kg 酵母水解物，在第 2 阶段提供基础日粮+100mg/kg 益生菌+400mg/kg 副益生菌混合物。第 14 天和第 42 天，TRT1 和 TRT2 组的猪比 CON 组的猪重。第 1-14 天、第 15-42 天和第 1-42 天的生长速度以及第 1-14 天的饲料效率受处理的影响相似，而第 15-42 天和第 1-42 天的 TRT2 猪的饲料效率显著更高。此外，TRT1 和 TRT2 的氮和能量消化率均高于 CON。在试验期间，TRT1 和 TRT2 的腹泻率低于 CON。因此，我们证明 PPY 补充与 ZnO 一样，能够改善断奶仔猪的生长性能和养分消化率，并改善断奶后腹泻。
