Somatic parameters of control and obese female mice and embryo production on day 2 of pregnancy in fertilized mice.
| Control mice | Obese mice | |
|---|---|---|
| Female mice (n) | 67 | 93 |
| Average body weight (g) | 19.04 ± 0.28a | 24.32 ± 0.17b |
| Average body fat (% of body weight) | 7.99 ± 0.05a | 11.94 ± 0.11b |
| Fertilized embryo donors (n) | 39 | 49 |
| Average number of embryos per dam | 10.85 ± 0.47 | 11.27 ± 0.43 |
| Number of isolated embryos | 423 | 552 |
| Embryos at the two-cell stage (%) | 91.25 | 89.49 |
Results are expressed as the mean values ± SEM or as percentages. Different letters in superscript indicate a significant difference: body weight: Student’s t-test (P < 0.001); body fat: Mann–Whitney test (P < 0.001); number of embryos per dam: Mann–Whitney test (P > 0.05); embryos at the two-cell stage: chi-square test (P > 0.05).
