Theriogenology, 1998 Superovulation in goats is frequently restricted by the cost of gonadotropin or the handling requirements. In this situation PMSG has the advantage of a lower cost and single dose protocol, but the variability of response obtained restricts its use. Thus, 2 alternative treatments with the advantages of PMSG were tested. In Experiment 1, we compared the

IGF-1 Deficiency Serves as an Integrated Biomarker Pathogenic Driver and Predictor in Poor Ovarian Response. [PDF]
Adv Sci (Weinh)IGF‐1 deficiency underlies poor ovarian response (POR), as reduced levels in follicular fluid and granulosa cells impair antral follicle formation and compromise reproductive outcomes. Including IGF‐1 as a biomarker significantly enhances the accuracy of models predicting both PORrisk and pregnancy success.

The Use of Bovine Anti-PMSG Serum in Beef Cattle after PMSG-Superovulation.
Journal of Veterinary Medical Science, 1992 Thirteen beef cows were superovulated using 4,000 i.u. of pregnant mare serum gonadotrophin (PMSG) on days 9 to 14 of the estrous cycle, followed by two injections of 500 micrograms prostaglandin F2 alpha analogue (PGF2 alpha) 48 and 55 hrs later. Seven of them were injected intramuscularly with bovine anti-PMSG serum 12 hrs after the first signs of ...
