A total of one hundred and forty, 28 day-old weaner pigs [Duroc × (Yorkshire × Landrace)] with an initial body weight (BW) of 6.56 ± 1.25 kg were used in a six-week treatment (7 replicate pens per treatment; barrows, and 2 gilts/pen) to evaluate the effect of low-nutrient-density diet supplement with probiotic mixture supplementation on the growth performance, nutrient digestibility, faecal microbial and gas emission of weaner pigs. Pigs fed low-density diet with probiotic mixture supplementation had linearly increased (p = 0.028, 0.014) the body weight (BW) at weeks 3, and 6. Moreover, average daily gain (ADG) was linearly improved (p = 0.018, 0.014, 0.014) at weeks 3, 6 and the overall experiment. However, there were no interactive effects found on the nutrient digestibility of dry matter (DM), nitrogen (N) and energy (E) throughout the experiment. Dietary inclusion of a low-density diet with probiotic mixture supplementation has improved the faecal lactobacillus counts linearly, but E. coli was unaffected during the trial. On day 42, Ammonium gas emission was significantly decreased in pigs fed a low-density diet with probiotic mixture supplementation. However, H₂S, acetic acid and CO₂ were not significantly affected by the probiotic mixture supplementation diet. Low-density diet with probiotic mixture supplementation had positively affected the growth performance, faecal microbial and faecal gas emission on weaner pigs.

添加益生菌混合物（Bacillus subtilis ms1、B. licheniformis SF5-1 和 Saccharomyces cerevisiae）的低营养密度日粮对断奶仔猪生产性能的影响

总共使用 140 头 28 日龄断奶猪 [Duroc × (Yorkshire × Landrace)]，初始体重 (BW) 为 6.56 ± 1.25 kg，进行为期六周的处理（每次处理 7 个重复栏; 手推车和 2 头后备母猪/栏）评估低营养密度日粮添加益生菌混合物对断奶仔猪生长性能、营养消化率、粪便微生物和气体排放的影响。饲喂添加益生菌混合物的低密度日粮的猪 在第 3 周和第 6 周时体重（BW）呈线性增加（ p = 0.028, 0.014）。此外，平均日增重（ADG）呈线性增加（ p = 0.018, 0.014, 0.014) 在第 3 周、第 6 周和整个实验中。然而，在整个实验过程中，没有发现对干物质 (DM)、氮 (N) 和能量 (E) 的养分消化率的交互影响。膳食中添加益生菌混合物的低密度饮食可以线性提高粪便乳酸杆菌的数量，但在试验期间大肠杆菌不受影响。在第 42 天，饲喂低密度日粮并添加益生菌混合物的猪的氨气排放量显着降低。然而，H ₂ S、乙酸和 CO ₂益生菌混合物补充饮食没有显着影响。添加益生菌混合物的低密度日粮对断奶仔猪的生长性能、粪便微生物和粪便气体排放产生了积极影响。
