Since 1978, the current preferred and most common method to transfer cattle embryos into synchronized recipients is via nonsurgical techniques. The embryo is loaded into a small plastic straw (0.25 mL) fitted into a specialized (Cassou-type) pipette (ie, artificial insemination gun).

2024年3月9日 · Embryo transfer in cattle involves several key steps: synchronizing the donor and recipient cows’ estrous cycles, collecting embryos from the donor cow post-fertilization, evaluating and storing viable embryos, and finally, implanting …

Most female breeding cattle produce one calf per year. Embryo transfer (ET) allows a producer to quickly multiply the genetics of the top females in the herd. When artificially inseminated with semen from bulls with high genetic merit, these top females produce calves with …

The embryo transfer process begins with cows receiving a hormone treatment to produce more than one ovulation (egg) at a time. The cows are then artificially inseminated with bulls also possessing desirable genetics.

Embryo transfer is one step in the process of removing one or more embryos from the reproductive tract of a donor female and transferring them to one or more recipient females. Embryos also can be produced in the laboratory via techniques such as in vitro fertilization or somatic cell cloning.

2023年10月13日 · In recent years, we’ve seen a global increase in cattle embryo production, reaching, in 2021, almost 1.5 million bovine embryos transferred according to the data collated by the International Embryo Technology Society (IETS).

4 天之前 · Bovine (taxon- Bos taurus) development is studied extensively due to the commercial applications of cattle both for milk and meat production. There is some variation in the gestation period (279-290 days) for the different breeds.
