Table 1. Alpha diversity indices of the three particulate matter groups
Particulate matter group1) | Observed OTUs | Chao1 | Shannon | Inverse Simpson |
I-NPH (n = 3) | 245.33a | 253.28a | 4.00a | 0.75a |
I-FPH (n = 3) | 268.00a | 300.54a | 3.49a | 0.76a |
O-PH (n = 3) | 224.67a | 233.33a | 2.94a | 0.62a |
Means were compared among the three PM groups using an ANOVA followed by Duncan’s multiple range test.
Means with the same superscript letter represent non-significant differences (p > 0.05).
OTU, operational taxonomic unit; I-NPH, inside the nursery pig house; I-FPH, inside the finishing pig house; O-PH, outside of the pig house.
