Table 3.

Latency to enter the nest box in females that nursed on postpartum days 1-3, relative to parity and agent injected icv^* (mean±se; minutes)

Group	Day 1	Day 2	Day 3
Primiparous-VEH	0.2±0.2	5.4±5.4	5.16±4.8
Primiparous-OTA	4.4±2.3	0.8±6.0	2.4±2.3
Multiparous-VEH	0±0	0±0	0±0
Multiparous-OTA	0±0	0±0	1.3±1.3

^*data derived from the number of nursing does shown in Table 2. A two-way ANOVA was used to determine, on days 1, 2, and 3: a) the effects of parity and injected agent; b) a possible interaction between those two factors
