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.
