Formate conc. | 0 mg/ml | 20 mg/ml | 0 mg/ml | 30 mg/ml |
---|---|---|---|---|
No. Litters | 15 | 10 | 13 | 14 |
Mean litter size | 6.90 ± 0.50 | 9.00 ± 0.90* | 7.00 ± 0.60 | 9.57 ± 0.40** |
Mean crown-rump length (mm) (n) | 7.78 ± 0.14 (25) | 7.683 ± 0.04 (90) | 7.88 ± 0.07 (47) | 7.78 ± 0.03 (133) |
Mean litter size of dams supplemented with 20 mg/ml or 30 mg/ml formate was larger than in control groups (*p < 0.05, **p < 0.01). The crown-rump length of embryos at E12.5 did not differ among experimental groups.
