| الملخص≠ | Apparent Total Tract Digestibility (ATTD) is a measure of the proportion of a nutrient consumed in feed that is absorbed by the animal, calculated from the difference between dietary intake and fecal excretion. Standardized since the 1970s, ATTD is essential for quantifying the bioavailability of nutrients in feedstuffs, formulating balanced diets, and comparing the nutritive value of different feed ingredients across diverse animal species. | Neutral Detergent Fiber (NDF) and Acid Detergent Fiber (ADF) analysis is a chemical fractionation method that separates feed components into digestible and indigestible portions based on their resistance to sequential detergent treatments. Developed by Peter J. Van Soest in the 1960s, NDF/ADF analysis provides rapid estimates of forage quality and feed digestibility, making it fundamental to ruminant nutrition and feed evaluation worldwide. |
