Estrus Detection/Evidence
Method evidence record

Estrus Detection

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.
