The Studies on Embryo Production from Hanwoo Cows with High Offspring Meat Quality Grade and Embryo Transfer

The Comparison Between the Pregnancy Outcome after Easy Embryo Transfer and Difficult Embryo Transfer

Background: The role of embryo transfer (ET) in the success of in vitro fertilization/intra cytoplasmic sperm injection treatment is not well understood. In the present study we classified ET technique as difficult and easy types according to certain strict criteria, and compared the pregnancy outcome of the two ET types. Methods: This study was performed retrospectively on 295 infertile patien...

Quality of embryos produced from dairy cows fed whole flaxseed and the success of embryo transfer.

The objective of the experiment was to determine the effects of fat supplementation on embryo quality of dairy cows and the subsequent success of embryo transfer into recipient heifers fed the same sources of fat. A total of 30 lactating Holstein cows were allotted on d 18 postpartum to 2 groups of 15 donor cows blocked for similar calving dates. Total mixed diets based on silage and fat supple...

Comparison between Conventional Blind Embryo Transfer and Embryo Transfer Based on Previously Measured Uterine Length

The consequences of metabolic changes in high-yielding dairy cows on oocyte and embryo quality.

Unsatisfactory reproductive performance in dairy cows, such as reduced conception rates, in addition to an increased incidence of early embryonic mortality, is reported worldwide and has been associated with a period of negative energy balance (NEB) early post partum. Typically, NEB is associated with biochemical changes such as high non-esterified fatty acid (NEFA), high β-hydroxybutyrate (β-O...
