الملخص	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.	Body condition scoring (BCS) is a systematic visual assessment of cattle body fat reserves and nutritional status. Formalized by dairy nutritionists in the 1980s-1990s (Edmonson and Ferguson), BCS integrates palpation of bony landmarks and observation of body shape to quantify energy stores on a standardized scale. The method is essential for nutritional management, health monitoring, and reproductive performance in dairy and beef cattle.
