Model-adjusted probability for calves to die of neonatal calf diarrhea for calves born to dams of different ages. Error bars represent the standard error of the mean. The outcomes of variables with different superscripts are statistically different (P≤.05). Compared with calves born to mature cows, calves born from heifers were 4 times more likely to die (relative risk = 4).
