Across all treatment groups, DIM at the start of the TAI protocol affected P/AI (42.3, 49.5, and 53.9% for 80 DIM, respectively; P < 0.03), but neither parity number (46.5, 50.4, and 48.4% for parity 1, 2, and ≥3, respectively; P = 0.6) nor BCS (44.0, 49.4, and 58.6% for ≤2.50, 2.75–3.25, and ≥3.50, respectively; P = 0.18) affected P/AI (Table 2).
