Σύνοψη	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.	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.
