Maturity is the key factor that has the most influence on forage quality. As plants mature, their nutritional content changes, typically leading to decreases in digestibility and protein levels while increasing fiber content. Younger plants are often high in protein and easily digestible, making them more valuable as forage for livestock. In contrast, as plants reach maturity, they develop more lignin, a component of cell walls, which makes the forage coarser and less palatable. This change in nutritional composition fundamentally affects how well livestock can utilize the forage for growth and production.

While color, flavor, and texture can all give some indication of forage quality, they are not as directly correlated with nutritional value as maturity is. Color may indicate certain characteristics, but it doesn’t provide a complete picture of nutrient content. Flavor can influence livestock preference, but it does not determine the nutritional quality. Texture, similarly, can relate to the energy expenditure required for digestion but does not encompass the comprehensive nutrient profile that is affected by maturity. Hence, maturity stands out as the primary determinant of overall forage quality.
