  1. Relative intensities were measured in plasma samples of control group (n = 5), OVX group (n = 6), OVXG2 (n = 3) and OVXG5 (n = 3) using a linear mixed model. Results are fold changes (FC) of the metabolite abundance between the OVX and control groups, between the OVXG5 and the OVX groups and between the OVXG2 and the OVXG5 groups from month one to month five, among identified compounds by LC-MS
  2. FC with a value > 1 indicates a relatively higher intensity present in treated ewes, whereas a value < 1 indicates a relatively lower intensity compared with their respective control animals
  3. All FC values in bold are significant (p < 0.05)
  4. p calculated using post-hoc Fisher’s least significant difference (LSD) test for pair-wise multiple comparison of the group means
