This study determined whether the interval from estrus to ovulation was altered by giving P.G. 600 to sows at weaning. Mixed-parity sows received P.G. 600 i.m. (n = 72) or no treatment (n = 65) at weaning (d 0). Beginning on d 0, sows were observed for estrus twice daily. At the onset of estrus and thereafter, ultrasound was performed twice daily to determine the average size of the largest fol...
This study aimed to assess frozen-thawed embryo transfer (FET) outcomes in natural, hormone replacement treatment (HRT) and semi-HRT cycles. This was a retrospective cohort study of 5414 cycles of patients in an academic hospital. Patients were grouped as 2216 natural cycles, 1180 semi-HRT cycles, and 2018 HRT cycles. Primary outcome measures were implantation rate, clinical pregnancy rate and ...
In sheep, follicle populations are very responsive to dietary intake. Definitions of effect of nutrition on ovulation rate have been identified 1) static effect, 2) dynamic effect and 3) immediate effect. An example of the immediate effect is short-term lupin grain supplementation for 4-6 days during the end of luteal phase prior to ovulation. This treatment increases the number of follicles an...
On the day of ovulation and next on day 7 after ovulation the ovaries of 20 sheep were examined using the transrectal ultrasound method. To verify the results, similar examination was made with the laparoscopic method. Depending on the stage of the sexual cycle (day 1 vs day 7) the number of Graafian follicles (∅ ≥5 mm) was determined as well as the total number of corpora lutea found in both o...
