| 요약≠ | 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. | Semen quality evaluation is a systematic assessment of male animal reproductive capacity, measuring sperm characteristics and overall breeding soundness. Developed by veterinary andrologists in the 1970s, the practice combines objective measures—sperm concentration, motility, morphology—with functional tests to predict fertility potential. Evaluation is essential for identifying suitable breeding animals, managing reproductive health, and ensuring successful artificial insemination (AI) programs. |
