| 摘要≠ | Meat quality assessment is a systematic evaluation of carcass and meat characteristics that determine suitability for consumption and market value. Formalized by the USDA and meat scientists in the early 20th century, the practice integrates objective measurements—color, marbling, tenderness, water-holding capacity—with sensory evaluation to assign quality grades. Assessment guides pricing, processing decisions, and genetic selection to improve consumer satisfaction. | 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. |
