Table 2.

Frequency of LH pulses in postpartum anestrus ewes in relation to infusion with kisspeptin (120 µg over 6 h) or saline, with data pooled for suckling treatment. Pulse frequency was measured over 6 h, both before and during infusion.

	Before Infusion	After Infusion	Mean
Saline (control)	1.63 ± 0.38 ae	1.75 ± 0.25 ae	1.69 ± 0.22 e
Kisspeptin	1.63 ± 0.18 ce	3.88 ± 0.48 df	2.75 ± 0.38 f
Mean	1.63 ± 0.20 aa	2.81 ± 0.38 b

By row (a, b; p ≤ 0.05, or c, d; p ≤ 0.01), or column (e, f; p ≤ 0.05), different letters indicate statistically significant differences.
