| 1 | Effect of Bacillus subtilis and Bacillus licheniformis supplementation in diets with low-and high-protein content on ileal crude protein and amino acid digestibility and intestinal microbiota composition of growing pigs显示文摘Background: Bacillus spp. seem to be an alternative to antimicrobial growth promoters for improving animals' health and performance. However, there is little information on the effect of Bacillus spp. in combination with different dietary crude protein(CP) levels on the ileal digestibility and microbiota composition. Therefore, the objective of this study was to determine the effect of Bacillus spp. supplementation to low-(LP) and high-protein diets(HP) on ileal CP and amino acid(AA) digestibility and intestinal microbiota composition.Methods: Eight ileally cannulated pigs with an initial body weight of 28.5 kg were randomly allocated to a rowcolumn design with 8 pigs and 3 periods of 16 d each. The assay diets were based on wheat-barley-soybean meal with two protein levels: LP(14% CP, as-fed) and HP diet(18% CP, as-fed). The LP and HP diets were supplemented with or without Bacil us spp. at a level of 0.04%(as-fed). The apparent ileal digestibility(AID) and standardized ileal digestibility(SID) of CP and AA was determined. Bacterial community composition from ileal digesta was analyzed by Illumina amplicon sequencing and quantitative real-time PCR. Data were analyzed as a 2 × 2 factorial design using the GLIMMIX procedures of SAS.Results: The supplementation with Bacillus spp. did not affect both AID and SID of CP and AA in growing pigs.Moreover, there was no difference in AID of CP and AA between HP and LP diets, but SID of cystine, glutamic acid,glycine, and proline was lower(P < 0.05) in pigs fed the HP diets. The HP diets increased abundance of Bifidobacterium spp. and Lactobacillus spp.,(P < 0.05) and by amplicon sequencing the latter was identified as predominant genus in microbiota from HP with Bacillus spp., whereas dietary supplementation of Bacillus spp. increased(P < 0.05) abundance of Roseburia spp.Conclusions: The HP diet increased abundance of Lactobacillus spp. and Bifidobacterium spp.. The supplementation of Bacil us spp. resulted in a higher abundance of healthy gut associated bacteria without affecting ileal CP and AA digestibility, whereas LP diet may reduce the flow of undigested protein to the large intestine of pigs. | Chanwit Kaewtapee Katharina Burbach Georgina Tomforde Thomas Hartinger Amelia Camarinha-Silva Sonja Heinritz Jana Seifert Markus Wiltafsky Rainer Mosenthin Pia Rosenfelder-Kuon | 2017 | Journal of Animal Science and Biotechnology2017，8，3： | 5 |
