Shorthorn and Bonsmara type beef heifers from two breeding seasons were allocated to a high (H), medium (M) and low (L) level of nutrition after weaning at 7 months of age. The feeding levels were applied for 145 days (1972 heifers) and 118 days (1973 heifers). The H groups produced more calves during the first calving seasons. The L groups maintained higher mean calving percentages during the subsequent production years, mean values being 75,3 (H), 80,7 (M), and 82,7% (L) for the 1972 heifers, and 75 (H), 68 (M), and 83% (L) for the 1973 heifers.
