| Treatments | Experimental group | Control group | SEM | P-value |
|---|---|---|---|---|
| CSC | 23.77 | 19.98 | 3.40 | 0.49 |
| CSF | 23.46 | 13.66 | 3.20 | 0.07 |
| CSA | 33.06 | 20.99 | 3.40 | 0.04 |
| CSFA | 22.89 | 21.92 | 3.60 | 0.88 |
SEM = standard errors of the mean; CSC = carrier infusion; CSF = milk fat precursor infusion; CSA = milk protein precursor infusion; CSFA = the mixed infusion of milk fat and protein precursors.
