AB  - The use of milk replacer instead of whole milk may be an economical alternative to calf-rearing systems. However, together with the volume fed, its composition is critical for high performance, especially regarding the origin of the protein. Two milk replacers with different protein content were evaluated to see the effect on the performance of calves. Thirty-three Holstein calves were distributed in the treatments: (1) High Volume and Low Protein (HV/LP), control group: 8 liters, 19.5% CP; (2) High volume and high protein (HV/HP): 8 liters, 23.7% CP and (3) Low Volume and High Protein (LV/HP): 6 liters, 23.7% CP. Calves were gradually weaned from the seventh week of life. Starter feed intake and fecal score were recorded daily. Weekly, calves were weighed, body measurements taken and blood samples were collected for metabolites analysis. Fecal score was lower (P>0.05) for animals in treatments HV/LP. Animals in treatments HV/HP had greater number of days in diarrhea (P
