Knowing how to raise grassfed goats for profit is all about using your resources well—both financially and ecologically. Goats are designed to browse small shrubs and other short plants, and they do an excellent job of gleaning nutrients from what we would consider weeds. So give them plenty to browse on.
Some farmers let their goats wander on large tracts of land; others section the land into smaller pastures and rotate the goats, allowing used portions to grow back. Make sure that pregnant and nursing does, as well as young kids, have access to the areas with the best nutrition, as it makes the biggest health difference to them.
Grassfeeding goats is particularly important for breeding stock (it makes a healthier goat) and milk goats (the nutrition creates a higher quality milk). Some meat goat farmers may choose to feed their goats grain to add weight, but the meat of grassfed goats is higher quality (if not higher weight) and should still fetch a good price.
