Abstract

Tweint-Four Holstein calves were used distributed on a completely radomized, with eight repetition and three treatments: integral milk (IM) and two types of comercial milk replacer DestetorÃ’ (CMRD) and LactalÃ’ (CMRL), during the period of suckling (60 days), and the studied variables were: dry matter intake (DMI) , total digestible nutrients intake (TDNI), crude protein intake (CPI) and feed conversion (FC). The consumption of total dry matter pre weaning, during 60 days, was higher to the treatment CMRD (P<0.05). The daily averages of total DMI were 0.79; 0.94 and 0.68kg calf-1 to the treatments IM, CMRD and CMRL respectively. Both the TDNI and the CPI slowed no differences (P>0.05) at the sucking period, and the daily averages to the treatments IM, CMRD and CMRL respectively of 0.19; 0.28 and 0.21kg calf-1, to TDNI and 0.04; 0.06 and 0.05kg calf-1 to CPI. The FC was similar to the three treatments (P>0.05) at the total period (TP), even so, at the intermediate period, the treatment CMRD slow better responses (P<0.05). The averages of FC at the total period were 2.68; 2.14 and 2.95 to the treatments WM, CMRD and CMRL, respectively.
