Purpose of the development: Development provides an increase in the reproductive ability donor cows in 2-15 times (from one donor cow can get 5-20 calves per year instead of 3-6 calves in a lifetime), which increases the effect of the breeding of 3-5.

Recommended application field: In large dairy cattle breeding enterprise.

Technical characteristic: Ukrainian technology transplant bovine embryos guarantees a high level of superovulation (12-14 corpora lutea in the ovaries); obtaining 12.8 embryos and ova in one removal, including 5-8 full embryos; multiple (up to 23 times) the use of cows as donors of embryos; safe disposal and search embryos (95%); assessment taking into account the quality of embryos and stage of development; prevention of microbial contamination at all stages of the process; cryopreservation of embryos; transplant embryos (in one or both uterine horns); survival of native embryos on average - 41.3% (27,0-70,0%), thawed - 35% (25,0-50,0%); calves receiving transplants (alone or dual); microsurgical division of embryos.

Advantages over analogues: 1) Passive cooling fuser mode that provides freeze close to linear; 2) the value of the developed device is much lower cost analog.

The development stage readiness: Introduced in production

Technical and economic effect: Technology enables the rapid creation of high-producing dairy herds, obtaining animals with preset parameters, including sires. The cost of one embrioperesadki using freshly embryo is 2915 UAH. Milk productivity firstborn transplants increases depending on the economy in the first lactation at 455-1200 kg, for the second - to 325-655 kg, the third - by 295-412 kg compared with their peers. Use of embryo transfer technology Ukrainian cattle breeding programs allows for 5 years to completely replace the existing breed cows herd desired breed.

Description of the development:
()
The technology consists of stages: creation of the donor herd; selection of cows (heifers) - donors; synchronize estrus in donors and recipients, treatment of cows (heifers) - donor superovulation; artificial insemination of cows (heifers) - donors; preparation of cows (heifers) - donor embryos to leaching; washout embryos in cows (heifers) - donors; search and evaluation of embryo quality and prediction of their survival; short-term storage of embryos; cryopreservation of embryos and their long-term storage; Preparation of native embryos for transplanting; microsurgical division of embryos; create groups of recipients with heifers or cows; Preparation of animals - recipients into account the characteristics of the corpus luteum of the ovary; non-surgical embryo transfer; determining the outcome of embryo transfer and receipt of calves - transplants.
