Measurement	Milk production¹			SEM	P-value
Measurement	Low	Mod	High	SEM	P-value
AI pregnancy rate, %	57^a	55^a	44^b	3	0.02
Final pregnancy rate², %	81^a	86^b	75^c	2	0.03

^a–c

Means with different superscripts differ (P ≤ 0.05).

Milk production groups: Low (6.57 ± 1.21 kg), Mod (9.02 ± 0.60 kg), or High (11.97 ± 1.46 kg).

Final pregnancy rate after a 60 ± 5 d breeding season with cleanup bulls.
