Table 1.
Distribution of DG29 results between days 29 and 36 post-insemination for cattle that were pregnant or nonpregnant as determined by ultrasonographic examination at D30
| Number of cattle inseminated (artificial insemination or embryo transfer)
|
||
|---|---|---|
| Pregnant by ultrasound | Nonpregnant by ultrasound | |
| Pregnant by DG29 | 162 | 13 |
| Nonpregnant by DG29 | 1* | 26 |
| Total | 163 | 39 |
Based on DG29 results between days 29 and 36, one heifer that had been classified as pregnant at day 14, but nonpregnant at days 20, 29, and 59 and was recorded by the veterinarian as having had an embryonic mortality at day 60, was included in this group.
