Abstract: Nineteen ewes received 200 mg of pFSH administered in eight decreasing doses from Days 1 to 4, starting three days before CIDR® device removal. Ten ewes received an injection of 350 ?g of estradiol benzoate at CIDR® device insertion (Group E) and nine animals served as controls (Group C). B-mode and spectral Doppler ultrasonographic examinations were performed daily throughout superovulatory treatment to enumerate ovarian antral follicles and to determine ovarian blood flow indices, respectively. There were no differences (P > 0.05) in superovulatory responses between left and right ovaries/uterine horns or the two groups of animals. End-diastolic velocity (EDV) and mean velocity (Vm) values were greater (P < 0.05) on Days 1 and 2, and peak systolic velocity (SVp) was greater (P < 0.05) on Day 3 in Group C than in Group E. In Group E 15 correlations was recorded among indices (SVp, Vm, EDV, flow velocity integral-FVI, and pulsatility index-PI) and follicles numbers in different size classes on Days 1, 2 and 4, and seven correlations among indices (SVp, EDV, Vm, and vascular resistance index-RI) and superovulatory/embryo results (numbers of regressing corpora lutea, numbers/percentages of degenerated embryos and viability rates) on Days 1, 2 and 3. In Group C, there were three correlations among EDV and RI and medium-sized/large follicle numbers on Days 1 and 3, and five correlations among indices (EDV, RI and PI) and superovulatory/embryo results (numbers of luteinized unovulated follicles, degenerated embryos and unfertilized eggs) on Days 2 or 4. There was a lack of consistency in the velocimetric correlates of antral follicle numbers and superovulatory responses between the left and right side. Therefore, the usefulness of ovarian arterial indices to predict ovine superovulatory outcomes remains equivocal and requires further confirmatory studies.

Ooplasmic transfer (01) has been used in basic mouse research for studying lhe segregation of mtDNA, as well as in human assisted reproduction for improving embryo development in cases of persistent developmental failure. Using cattle as a large-animal model, we demonstrate that lhe moderate amount of mitochondria introduced by OT is transmitted to lhe offspring's oocytes; e.g., modifies lhe germ fine. The danar mtDNA was detectable in 25% and 65% of oocytes collected from two females. Its high variation in heteroplasmic oocytes, ranging from 1.1% to 33.5% and from 0.4% to 15.5%, can be explained by random genetic drift in lhe female germ line. Centrifugation-mediated enrichment of mitochondria il1 lhe pole zone of lhe recipient zygote's ooplasm and its substitution by danar ooplasm led to elevated proportions of danar mtDNA in reconstructed zygotes compared with zygotes produced by standard OT (23.6% :!: 9.6% versus 12.1% :!: 4.5%; P <0.0001). We also characterized lhe proliferation of mitochondria from lhe OT parents-the recipient zygote (Bos primigenius taurus type) and lhe danar ooplasm (B. primigenius indicus type). Regression analysis performed for 57 tissue samples collected from lhe seven OT fetuses at different points during fetal development found a decreasing proportion of donor mt DNA (r2=0.78). This indicates a preferred proliferation of recipient of the OT recipeint expressinf a B. primigenius indicus phenotype. |
