Global test and pairwise tests in beta diversity analysis (weighted Unifrac) of cecal samples of broiler chickens fed diets with different enzymatic associations.
| Item | R significance1 | P value |
|---|---|---|
| Global test | 0.092 | 0.080 |
| Pairwise test | ||
| Positive control (PC) vs. negative control (NC)2 | 0.241 | 0.041 |
| PC vs. NC + Amylase3 | 0.354 | 0.035 |
| PC vs. NC + Amylase + Xylanase3 | 0.185 | 0.056 |
| PC vs. NC + Amylase + Xylanase + Protease3 | 0.074 | 0.180 |
1
R value ranges from -1 to 1: the pairs are more similar when the R index is closer to 0 and the pairs are different from each other when the R index is close to 1.
2
PC, positive control (meeting the nutritional requirements of broilers without the enzyme inclusion); NC, negative control (reduction of 100 kcal/kg).
3
Amylase (RONOZYME HiStarch, 80 KNU/kg), xylanase (RONOZYME WX, 100 FXU/kg), and protease (RONOZYME ProAct, 15,000 PROT/kg).
