1CON = conventional cow-calf system without supplementation of calves. PCON = calves were creep fed. ENZ = calves were creep fed with an enhanced feed containing xylanase; 2ADG Period1 = ADG during the 105-day feeding trial (last third of suckling phase); 3ADG Period2 = ADG during the first 4 weeks after weaning. *Results shown as mean and standard deviations (in parenthesis). None of the means within each row were significantly different (P ≥ 0.05) according to Fisher’s Least Significant Difference test.
