Repeated ovum pick-up in Italian Mediterranean buffalo cows

Theriogenology, 1996
The potential of the ovum pick-up technique, used over a long period, was evaluated in 6 Italian Mediterranean buffalo cows that had more than 500 d open. The cows were submitted to ovum pick-up twice weekly for 2 mo. An additional 2-mo cycle of ovum pick-up was performed in 3 of the buffalo.

Progesterone Device Use Improves Ovum Pick-Up Efficiency in Acyclic Donors

Journal of Equine Veterinary Science, 2023
The aim of this study was to evaluate follicular dynamics and ovum pick-up (OPU) efficacy in untreated mares or mares treated with an intravaginal progesterone (P4) device during seasonal anestrus (acyclic) and during the breeding season (cyclic). Six mares (mean age = 5 years), were recruited into an ovum pick-up scheme that was performed every 14 ...

Utilizing the Laparoscopic Ovum Pick-Up Method for In Vitro Embryo Production in Prepubertal Anatolian Native Black Calves: A Promising Approach for Gene Banks and Endangered Species.

Animal science journal = Nihon chikusan Gakkaiho
Recent advancements in genomic technology have increased interest in using calves as oocyte sources through the laparoscopic ovum pick-up (LOPU) method, which shortens generation intervals and enhances genetic gain. This study aimed to produce embryos in

Embryo production by ovum pick up from live donors

Theriogenology, 2001
Embryo production by in vitro techniques has increased steadily over the years. For cattle where this technology is more advanced and is applied more, the number of in vitro produced embryos transferred to final recipients was over 30,000 in 1998. An increasing proportion of in vitro produced embryos are coming from oocytes collected from live donors ...

Ovum Pick Up: Which Day of the Estrous Cycle Should be Performed in Cattle?

Acta Scientiae Veterinariae
Backgraund: The first step in the in vitro embryo production (IVEP) procedure is to obtain high-quality and viable oocytes. Therefore, the ovum pick-up (OPU) method was developed in cattle. Ovum pick up in cattle is usually performed once or twice a week.

Effect of Fetal Calf Serum (FCS) Versus Polyvinylpyrrolidine (PVP) on in vitro Maturation of Oocytes Retrieved by Ovum Pick-up (OPU) in Sahiwal Cows

The Indian Journal of Animal Reproduction
The experiment was conducted to compare the effect of supplementation of fetal calf serum (FCS) versus polyvin ylpyrrolidine (PVP) on in vitro maturation (IVM) of the bovine oocytes collected by ovum pick-up (OPU) method.  Cumulus oocyte complexes (COC’s)

Effect of follicle ablation before ovum pick-up in Girolando cattle

Journal of Scientific Agriculture
The present study characterized the effect of follicle ablation (FA) intervals on the follicular population and the quantity and quality of cumulus-oocyte complexes (COCs) from 1/2 and 1/4 Girolando donors (n=125 and n=110, respectively) at Ovum Pick-Up (
