Resum	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.	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.
