Uterine Contraction in Sows during Estrus and Puerperium, and in Sows with Multiple Follicular Cysts.

Influence of follicular ablation during lactation on postweaning interval to estrus, ovulation rate, and endocrine function in sows.

Duroc sows farrowed second litters in March and lactated 35 +/- 2 days. At 36 hr before weaning, electrocautery of follicles greater than or equal to 3 mm in diameter (n = 8) or sham surgery (n = 5) was performed to test the hypothesis that ablation of medium-sized follicles would prolong the duration of postweaning anestrus. Number of follicles and diameters at surgery were: 1.3 +/- .6 (greate...

Decreased follicular size during late lactation caused by treatment with charcoal-treated follicular fluid delays onset of estrus and ovulation after weaning in sows.

The weaning to estrus and weaning to ovulation intervals in sows are controlled by ovarian follicular growth after weaning. Longer intervals could be caused by smaller diameter follicles at weaning that take more time to reach a preovulatory size. We addressed this hypothesis by decreasing the diameter of follicular populations before weaning and then measuring follicular development and interv...

The Dynamics of Bacterial Contamination of the Genital Organs in Sows during the Puerperium

Vlcek Z., R. Svo bodova: The Dynamics of Bacterial Contamination of the Genital Organs in Sows During the Puerperium. Acta Vet. Brno, 49, 1980: 231-236. In 47 primiparous Large White sows, slaughtered at various times during the puerperium, the extent, degree and dynamics of bacterial contamination of the genital organs, was ascertained. The frequency of bacteria in the cranial parts of the sex...
