Humic acid is a substance that is found in soil humus and is one of the main constituents of humus. It is also found in some fossil fuels, coal, highlands and ocean water. How humic acid is produced is not well understood, but is believed to be generally a byproduct of the metabolism of microorganisms. The term humic substances is generally used to refer to natural materials extracted from soil components. Humic acid affects feed intake, feed efficiency, egg weight and egg internal and external quality. The effects of humus have long been known to be a chemical compound derived from soil-borne substances and organisms. Humic acid can contain compounds such as phenyl, carbohydrates, esterified amino acids and other compounds. The use of humic acid has many advantages for animal health and growth. Humic acid has the ability to act as a layer in the mucous membrane of the epithelium against intestine and toxin infections. It affects the metabolism of carbohydrates and proteins of microbes and prevents infection and consequently the use of humic acid improves digestive function, digestion and absorption of nutrients, excretion of toxins from the body and enhances immune system thus, improves animal function and growth. Recent reports have been shown that using humic acid, especially in poultry nutrition, improves performance and growth.
