| 摘要≠ | Feed conversion ratio (FCR) is a key metric of nutritional efficiency in livestock, measuring the amount of feed consumed relative to animal growth or product output. Developed by animal nutrition scientists in the mid-20th century, FCR quantifies how efficiently livestock convert dietary nutrients into meat, milk, eggs, or other products. It is a primary driver of profitability in commercial animal agriculture and a focus of genetic selection in breeding programs. | 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. |
