| 概要≠ | IVF Embryo Grading is a standardized morphological assessment system for evaluating the quality and viability of embryos in assisted reproductive technology. First formalized by Gardner and colleagues in 1999, it uses microscopic examination to score embryos across multiple criteria, enabling clinicians to select the most viable embryos for transfer and improve pregnancy outcomes. | Body Condition Scoring (BCS) is a semi-quantitative visual and palpation assessment method used to evaluate the nutritional status and adipose tissue reserves of livestock, particularly dairy cattle, beef cattle, and small ruminants. Developed systematically in the 1980s, BCS provides a practical, non-invasive tool for herd management, reproductive performance prediction, and feed efficiency optimization. |
