HUMAN NUTRITION

Detailed explanation-1: -Starches and sugars, known as nonstructural carbohydrates are digested by enzymes and are absorbed in the foregut. Fiber components, cellulose and hemicellulose, known as structural carbohydrates are digested by microorganisms throughout the gut but primarily in the hindgut.

Detailed explanation-2: -The principle of carbohydrate fermentation states that the action of organism on a carbohydrate substrate results in acidification of the medium, detected by a pH indicator dye. Carbohydrate fermentation is the process microorganisms use to produce energy.

Detailed explanation-3: -Structural carbohydrates are fiber components like cellulose, pectin, fructan, and hemicellulose that are digested with the help of microorganisms in the hindgut. Energy: Both structural carbohydrates and non-structural carbohydrates are energy sources for horses.
