If we only consider what is best for forage and animal<br />

production, the decision on when to cut forages is a<br />

compromise between forage yield and quality (see<br />

following figure on page 84). For the first few days after<br />

cutting, forages regrow slowly as they have few leaves to<br />

intercept light for photosynthesis. This is followed by a<br />

few weeks of rapid leaf growth and production of good<br />

quality feed. If left uncut any longer, the quality of the<br />

forage drops as:<br />

the plants produce more and more stem, particularly<br />

when they start flowering,<br />

digestibility of stem is much lower than leaf,<br />

digestibility of old grass is much lower than young<br />

grass, and<br />

protein content decreases as the plant ages,<br />

particularly in grasses.<br />
