FIG. 3.

Day 14 conceptus morphology and measurements. Fertility-classified heifers were synchronized to estrus and received a high-quality in vivo produced embryo on Day 7 postestrus. All heifers were nonsurgically flushed on Day 14 (7 days post-ET) to recover the conceptus. If present, conceptus length and width were determined under a microscope. A) Representative conceptus morphology recovered from high fertile (HF), subfertile (SF), and infertile (IF) heifers. Bars = 1 mm. B and C) Conceptus length and area were not different (P ≥ 0.60) among the fertility-classified heifers. Data is presented as least squares means (LSM) with the standard error of the mean (SEM).
