After this period all heifers were managed as a single group for 150 days. Nutrient intake, behavior, body weight and other morphological measures were recorded in each animal. As a result of the experimental design THIGH heifers had a higher nutrient intake than TMEDIUM heifers, which was reflected in a higher daily weight gain, withers height, heart girth and hip width. However, treatments had no effect on these traits during the residual period.  aCRECIMIENTO  aNOVILLO  aFEEDING LEVEL  aGROWTH  aHEIFERS  aNIVEL DE ALIMENTACIÓN1 aMENDOZA, A.1 aCAJARVILLE, C.1 aBENTANCUR, O.1 aREPETTO, J.  tCiencia Rural, 48(3), art. no. e20161083, 2018.
