| 摘要≠ | Embryo transfer (ET) success evaluation is the systematic assessment of pregnancy establishment and calving outcomes following embryo implantation. Developed by reproductive physiologists in the 1970s-1980s, the method measures conception rates, pregnancy retention, calving rates, and calf viability to quantify the efficacy of ET programs and identify factors affecting outcomes. Success assessment is critical for optimizing ET protocols and managing investment in breeding programs. | Herd reproductive performance assessment integrates multiple metrics to evaluate the efficiency of breeding programs and overall population fertility. Formalized in the 1990s-2000s by dairy veterinarians and herd health specialists, the method combines individual animal records (conception rates, calving intervals) with population-level indicators (age structure, open days, pregnancy rate) to identify reproductive constraints. Assessment is fundamental to dairy profitability and sustainability. |
