Frequency of maternal behaviors

Maternal behaviors	Low LG (n = 10)	High LG (n = 13)
Licking and grooming	5.5 ± 0.45	12.95 ± 0.54**
Arched-back nursing	35.3 ± 2.38	40.6 ± 2.44
Flat-back nursing	37.2 ± 2.86	27.2 ± 2.27**
Passive nursing	6.7 ± 0.83	7.2 ± 0.73
No maternal contact	19.5 ± 2.71	19.1 ± 0.54

Mean (± SEM) percentage of maternal behavior averaged over the first 6 d postpartum. The frequency of the different maternal behaviors, including LG, was summed over the 6 d period, and percentages for each maternal behavior were calculated. Dams used in the current study differed in the percentage of LG and flat-back nursing averaged over the first week of life.
