Zusammenfassung	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.	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.
