Abstract

The objective of this study was to investigate the relationship between the plasma concentrations of vitamin A (VA), vitamin E (VE) and β-carotene (BC) during embryo collection in Japanese Black cows that had undergone superovulation treatment and the embryo collection results. Following superovulation treatment in 116 Japanese Black cows, we collected 1317 embryos by nonsurgical means seven days after artificial insemination. The collected embryos were classified into transferable embryos, unfertilized oocytes and degenerated embryos. After embryo collection, we collected blood samples from the cows and measured the plasma concentrations of VA, VE and BC. The cows were then divided into 2 groups depending on the plasma concentration of VA (L and H: <80 IU/dl and ≥ 80 IU/dl), VE (L and H: <150 μg/dl and ≥ 150 μg/dl) and BC (L and H: <150 μg/dl and ≥ 150 μg/dl). As a result, the number of collected embryos in the H group of VE was significantly (P
