Historically, amino acid requirements were determined by calculating the balance between dietary Nitrogen intake and nitrogen excreted in the liquid and solid wastes because proteins represent the largest nitrogen content in a body. A positive balance is where more nitrogen is consumed than is excreted which indicates that some of the nitrogen is being used by the body to build proteins. A negative nitrogen balance is where more nitrogen is excreted than is consumed whi…
