Effects of Partially Hydrolyzed Guar Gum Supplementation on the Fecal Microbiotas of Piglets

| Sumario: | Probiotics and prebiotics have become viable alternatives of growth-promoting antimicrobials in animal production. Here, we tested partially hydrolyzed guar gum (PHGG) as a possible prebiotic for piglets in the commercial farm. Five hundred and ninety-four piglets were used for the experiments, with 293 given a normal pig feed (control), while the rest the feed plus 0.06% (w/w) of PHGG (PHGG). One and three months post-PHGG supplementation, fecal samples were collected from randomly selected 20 piglets in each group and analyzed for microbiota and organic acid concentrations. Notably, the abundance of <i>Streptococcus,</i> and unclassified <i>Ruminococcaceae</i> were lower (<i>p</i> < 0.05) in PHGG than in control, one-month post-supplementation. <i>Lactobacillus</i> and <i>Prevotella</i> were higher (<i>p</i> < 0.05), while <i>Streptococcus</i> was lower (<i>p</i> < 0.05), in PHGG than in control, three months post-supplementation. The concentrations of acetate, propionate, and butyrate were greater in PHGG than in control, three months post-supplementation. Finally, PHGG grew faster and had fewer deaths until slaughter time (<i>p</i> < 0.05), than control. We concluded that PHGG not only was an effective prebiotic to alter gut microbiota of weanling piglets but also can possibly promote body weight accretion and health. |
