Influence of phenylalanine and lysine deficiencies on thyroid morphology in the chick

A study was conducted to investigate the effects of dietary phenylalanine and lysine deficiencies on thyroid morphology in chicks fed crystalline amino acid diets. Both mean follicle diameter and epithelial cell height were significantly reduced in birds fed either of the deficient diets as compared...

Summary:A study was conducted to investigate the effects of dietary phenylalanine and lysine deficiencies on thyroid morphology in chicks fed crystalline amino acid diets. Both mean follicle diameter and epithelial cell height were significantly reduced in birds fed either of the deficient diets as compared with controls. These results agree with previous studies on serum T4 and T3 concentrations where the effects of an amino acid deficiency were general and not limited to precursors of thyroxine.
