Most ratite diets are modified poultry diets, with changes in protein level and usually increased vitamin and trace mineral supplementation. Prepared feeds are available. There is much discussion as to whether all ratites should be fed the same diets. There may be different nutrient requirements among these species, as there are between chickens and turkeys. Some growers allow their birds access to forage, while others provide only the prepared feed.
Alfalfa works well in growing and breeding pens.
The general consensus is that ratites may require more fiber in the diet than chickens. Exact levels, however, are unknown. There is little research-based information concerning the production of these birds. Some research is underway, but useful results are slow in coming. It probably will be several years before research-based information is published in a usable form.
