概要	Feed ration formulation is the process of selecting and blending feed ingredients to meet animal nutrient requirements while optimizing cost and feed acceptance. Formalized by veterinary nutritionists in the 1960s-1970s, the method integrates knowledge of nutrient requirements (energy, protein, minerals, vitamins) with ingredient composition and cost data. Modern ration formulation uses linear programming and decision support software to identify cost-minimizing combinations that satisfy nutritional constraints.	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.
