    Cumulative survival chart. Proportion of cows that have ovulated over time in the groups of cows with a low (NEFAdry,low) and a high rate of lipolysis (NEFAdry,high) during the dry period, expressed by their respective NEFA levels prepartum. The NEFAdry,low cows tended to reach a greater proportion of ovulation after 42 d compared with NEFAdry,high cows (P=0.080).
