Things You'll Need
- Tree identification book
Instructions
Find local oak trees and identify them using a tree identification book. This is easier in the spring when the leaves are not too dense. Some trees produce acorns with more tannin than others. The Emory oak found in the southwestern United States and northern Mexico is low in tannin, as is the swamp oak, the burr oak and the Oregon white oak.
Collect acorns between late September and October. The exact number will depend on how many pigs are being fed and the percentage of acorns in their diet. The pigs owned by the La Quercia Company are fed a diet containing 60 percent acorns from September through to their slaughter in December. Bear in mind that high percentages of acorns in a pig's diet may outstrip the amount of free acorns available. Organic store-bought acorns can be expensive.
Feed the acorns to the pigs twice a day. Ensure that the pig's diet is supplemented with a balanced compound feed so that it gets all the nutrients it requires. If a pig consistently rejects the acorns, try collecting from a different type of oak tree.
