Ringkasan	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.	Growth curve fitting is the mathematical modeling of animal body weight and size changes over time. Developed by animal biologists and statisticians in the 1970s-1980s (Fitzhugh), the method applies nonlinear regression to weight data, extracting parameters that characterize growth rate, time to maturity, and asymptotic mature weight. Curve fitting supports comparisons of genetics, nutrition, and management effects on growth efficiency and enables prediction of market weight and slaughter timing.
