In this work 12 Holstein calves were used distributed in three treatment, on a completely randomized desing with four replicatin. The treatments were used, integral milk and two types of comercial milk replacer Lactal® and Destetor® to evaluate the digestive system alometric growthof the including, rumen and reticulum papillae heigth and omasum rigde growth. The animals were milking for 60 days and after slaughtring, their digest system organs were weighed and stomach complex compared (rumen, reticulum, omasum and abomasum). No difference (P>0.05) due to treatments were obseved for the proportions among the diferent stomach compartiments of the calves. However, differences (P<0.05) for the papillae height of rumen and for the rigde lenght of omasum were observed. The milk replacers in this work resulted in a good calve growth being an alternative source of feed during mlking period.
