Characterization of Local Algerian Population of Rabbit: Factors Influencing Fetal and Placental Development
Bibliographic record
Abstract
The objective of our work was to study the effect of parity the parity of the does, the intra uterine position and vascularization of the fetuses and their number per horn on, available uterine space and placentae development in the rabbit at two stages (nulliparous and primiparous). To this aim, twenty rabbit does of locally Algerian population were distributed in two groups of 10 each (nulliparous and primiparous). The does were mated and slaughtered on 24th day of gestation. In the group of fetuses receiving poor blood supply (? 4 blood vessels), the individual weight and the crown-rump were lower (- 24.4 and - 12.6% respectively; p < 0.05) compared to those with higher number of blood vessels (? 5). The intra uterine position affects significantly the individual weight of maternal placenta and the heavier one was located in the oviduct. Significant interaction between parity and the number of blood vessels was recorded for the individual weight of fetal placenta (p < 0.05). Available uterine space was lower in the primiparous, in the middle position and in the class of fetuses with lower blood supply. In primiparous, the horns with 5 or 6 fetuses presented a better vascularization than those with the same number in nulliparous (+25%). The fetal weight and crown-rump decreased when the number of fetus per horn increased (p<0.05). A significant interaction was recorded between the parity and the number of fetus per horn for the weight of maternal placenta (+ 15% and + 30% respectively in the horn within 3 or 5 fetuses in nulliparous; p < 0.05). Available uterine space was greater in nulliparous compared to the primiparous and decreased when the number of fetus per horn increased. These results suggest that available uterine space and fetal development at 24th of pregnancy are affected respectively by parity of the rabbit and the vascularization of the implantation site.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
