06.00.00 Agricultural sciences
Description
The researches of the quality of 34 donor cows estrus detection during superovulation induction period, after Pg F2α injections were carried out. The clinical heat index was set up and applied. The clinical heat index is clinical prognostic criterion of successfulness of superovulation induction and embryo productivity. It was shown that donor cows showing signs of oestrus during 48-72 hours after Pg F2α injections had the best embryo collection qualities while certain increase of degenerated or aborted embryos and unfertilized oocytes is determined in embryo collections from cows showing signs of oestrus before or after that period
