Total production (transferrable embryos) of IVD and IVP embryos1 in 2022 in cattle, sheep, goats, and horses, by region
1 cze 2020 · This review will focus on embryo recovery and transfer, cooled-shipped embryos, embryo freezing, oocyte freezing, oocyte collection and transfer, intracytoplasmic sperm injection (ICSI), and sexed semen. Embryo transfer procedures have been constant for many years and the costs have not changed.
Total production (transferrable embryos) of IVD and IVP embryos in 2021 in cattle, sheep, goats, and horses, by region. For the first time, over one million IVP cattle embryos were transferred worldwide, a 32.8% increase compared with 2020 (1,166,034 vs. 878,181, respectively).
Embryos purchased in high enough volumes could cost as little as $125 per embryo, putting ET at a comparable price level to artificial insemination (AI) services (Trans Ova, personal communication).
Total production (transferrable embryos) of IVD and IVP embryos in 2020 in cattle, sheep, goats, and horses, by region. The number of embryos actually transferred followed the same trends observed for embryos collected or produced in 2020, i.e., a decrease in IVD and an increase in IVP (-7.9% and +10.2%, respectively).
13 maj 2022 · Embryo transfer status was determined from the codes stored in pedigree records that report the donor dam, birth records for calving ease and stillbirth evaluations that report the recipient dam, and reproductive records stored in herd management software, and collected and transmitted by DRPC.
