- a,b,c Means within a row with no common superscript differ significantly (P < 0.05)
- 1 A 2 × 2 factorial arrangement with 2 supplemental levels of rumen-protected creatine pyruvate (RP-CrPyr) in basal diets (0 or 140 g/d for each cattle) and 2 transport treatment (transport 0 or 12 h before slaughter)
- 2 Transport × RP-CrPyr, the interaction between Transport and RP-CrPyr
- SEM Stand error of mean, MCP Microbial crude protein, NH3-N Ammonia nitrogen, TVFA Total volatile fatty acids
