Forage at the time of harvest is the cumulative result of plant growth and the environmental factors influencing the distribution of photosynthetically derived energy and nutrients in those plants. Environmental conditions of growth determine the plant composition which in turn controls the limits of nutritive value. Environmental temperature, which increases lignification is a dominant effect, while the effects of plant maturity (decreasing quality) and light (increasing quality) are secondary. Other factors include water, fertilization and disease which affect quality via plant development. Generally any factor that retards plant development tends to maintain quality. The combination of these factors cause different nutritive qualities in forages from differing geographical locations and between first cuttings in spring and affermath cuttings. Detergent fiber analyses or date of cutting are successful in predicting quality of temperate first cutings, but are less effective in dealing with aftermath cutting and tropical forages. It is difficult to provide a single criterion that will adequately characterize all forages. |
