    Abstract:
    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, H2 S, 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.
