Do our pet birds need to combine their proteins for complete nutrition?
If you're a vegetarian, or know any vegetarians, you'll know about combining proteins to complete them -- neither legumes nor grains provide all the amino acids we require by themselves but eaten together their aminos complement each other and complete the protein. Humans who choose a vegetarian or especially a vegan diet have to combine their plant proteins or risk ill health and dietary deficiencies
Of course we bird keepers feed our pets mixed seed grains and legumes, especially if we cook any of their chow at home. For instance, last night i cooked up a big mess of "birdie beans" which was lentils, and emmerwheat, with a batch of cooked quinoa added (and a great big double handful of 'tiel pellets, and another one of grated carrots, thrown in). I serve this concoction to Maggie and the 'keets on alternating days (other days, Maggie eats pre-soaked soggy fruit flavored pellets) in addition to their pellets-and-seeds mix and sprouts ,which they get every day.
I got to wondering -- do our feathered friends actually need the completed proteins the same way humans do? I'm aware that our nutritional needs aren't the same at all; should I be making sure my birds are eating a proper combination of beans and grains to complete their proteins?
