Nutritional Equivalency Report: Comparison of a Fortified Whole-Grain Diet (Nutri-Berries) with a Pelleted Diet for Companion Birds

Key Points

  • There are no clinically significant differences between cockatiels fed a pelleted diet and those fed the whole-seed balanced diet, Lafeber® Nutri-Berries.
  • Cockatiels fed Nutri-Berries group spend considerably more time consuming this diet than birds consuming pellets. This finding suggests enhanced foraging enrichment over a pelleted diet.

A clinical trial was conducted with cockatiels to compare a whole-seed balanced diet (Nutri-Berries) with that of a pelleted diet. Blood values, body weight, and other parameters were measured to assess the alternative diet’s clinical effects on birds . . .
