Zusammenfassung	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.	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.
