Quail egg yolks offer a wealth of nutrients. They are abundant in fats such as neutral fats, lecithin, and cholesterol, as well as essential minerals like calcium, phosphorus, and iron. Additionally, they are packed with high-quality protein and an array of vitamins including A, D, and B. Quail egg yolks play a significant role in brain development. Lecithin found in quail egg yolks can be broken down by cats and dogs, releasing choline. Choline travels through the bloodstream to the brain, promoting brain development in puppies and preventing cognitive decline in adult dogs while enhancing memory. Furthermore, lecithin aids in liver cell regeneration and boosts the body’s metabolism.
