A prepartum diet supplemented with oilseeds high in oleic or linoleic acid reduced GnRH-induced LH release in dairy cows during second week postpartum

Table 6 The mean diameter of the largest ovarian follicle in postpartum weeks 1 and 2 in each of the three dietary groups

Prepartum diet	Mean ± S.E. of follicle diameter (mm)
	Week 1^A	Week 2^A
Control	9.41 ± 1.34	13.90 ± 1.47
Canola	6.40 ± 1.47	13.80 ± 1.47
Sunflower	7.00 ± 1.47	10.90 ± 1.47

^AWeek1: First week after calving (n = 5 cows per treatment); Week2: Second week after calving (n = 5 or 6 cows per treatment). Follicle size was not influenced by treatment (P = 0.18) or treatment x week interaction (P = 0.45)
