Relative abundance of the mucosa-associated microbiota in the jejunum at phylum level in nursery pigs at day 45 fed normal or calcium and phosphorus deficient diets with bacterial 6-phytase supplementation at 2,000 FTU/kg feed
| Item | Phytase, FTU/kg of feed | SEM | P-value | |||
|---|---|---|---|---|---|---|
| NC1 | PC2 | 2,000 | NC vs. PC | PC vs. 2,000 | ||
| Proteobacteria | 44.55 | 44.04 | 58.79 | 15.65 | 0.978 | 0.439 |
| Firmicutes | 40.18 | 29.07 | 31.22 | 14.21 | 0.397 | 0.871 |
| Bacteroidetes | 11.23 | 15.45 | 1.80 | 5.26 | 0.581 | 0.092 |

1Negative control.
2Positive control with 0 FTU/kg feed of phytase. Six pigs were removed from the study with 1 from NC treatment, 1 from 0 FTU/kg feed treatment, 2 from 500 FTU/kg feed treatment, and 2 from 1,000 FTU/kg feed treatment due to morbidity (n = 66 total, n = 11 for NC, n = 11 for PC, n = 10 for the 500 FTU/kg of feed, n = 10 for the 1,000 FTU/kg of feed, n = 12 for the 2,000 FTU/kg of feed, n = 12 for the 5,000 FTU/kg of feed).
