It has been known for hundreds of years that certain diseases are associated with certain diets. However it was only in the early years of the 20th century that the specific compounds, now known as vitamins, which could prevent these effects in man and animals were identified. Vitamins are organic compounds which are required in small amounts in the diet to support normal growth and development and a range of physiological functions. The table below summarises the association of particular vitamins with certain problems which may be observed in poultry.
