a,b,c,d Means in a row with different letters differ (P < 0.05).
1Heifer calves were fed until weaning either ad libitum milk replacer (MR) or whole milk (M) that was offered for 30 minutes in 2 meals per day. The heifers were fed from 60 to 150 d of age the same ration and at 150 d of age each original group was divided into 2 sub-groups. One of the each subgroup was supplemented with 2% protein until 320 d of age. From 320 d of age all the heifers were housed and fed together until calving.
