| 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. | Estrus detection is the identification of the fertile period in female livestock, when ovulation is imminent and animals are sexually receptive. Formalized by reproductive physiologists in the 1960s-1970s, the practice combines behavioral observation, physical signs, and technology-enabled monitoring to identify the optimal timing for breeding. Accurate estrus detection is fundamental to reproductive efficiency, conception rates, and profitability in livestock operations. |
