Table 3.
Effect of the average DMI as a percentage of body weight (DMI%BW) and the average energy balance (EB) in the last 3 days prepartum on postpartum left displaced abomasum (LDA), indigestion, and other digestive disorders in the first 28 days postpartum.
| DMI%BW | EB (Mcal/day) | |||||
|---|---|---|---|---|---|---|
| Disorder | ORa | 95% CI | p-Value | ORb | 95% CI | p-Value |
| LDA | 1.03 | 0.95–1.13 | 0.45 | 1.03 | 0.94–1.12 | 0.58 |
| Indigestion | 1.09 | 1.04–1.15 | <0.01 | 1.09 | 1.04–1.14 | <0.01 |
| ODDZ | 1.08 | 0.99–1.18 | 0.07 | 1.08 | 0.99–1.16 | 0.08 |
ODDZ, other digestive disorders include sand impaction, cecal dilation, bloat, diarrhea, and constipation.
The odds ratio (OR) represents a 0.1 percentage point decrease in the average DMI%BW in the last 3 days prepartum, when the average DMI%BW ranged from 0.27% to 2.90%, with an interquartile range from 1.03 to 1.70%.
The OR represents a unit decrease in the average EB in the last 3 days prepartum, when the average EB ranged from −16.72 to 25.12 Mcal/day, with an interquartile range from −0.82 to 5.47 Mcal/day.
