| Сводка≠ | Milk yield recording is a systematic method for measuring and documenting the volume of milk produced by individual dairy animals across lactation cycles. Formalized in the early 20th century by dairy scientists including W. L. Gaines, the practice forms the backbone of modern dairy herd management and genetic improvement programs. It enables objective assessment of production performance and identification of high-producing animals for breeding. | 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. |
