| 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. | Somatic Cell Count (SCC) is a quantitative measure of the concentration of white blood cells and epithelial cells in milk, used as a primary indicator of udder health and the presence of mastitis in lactating cattle. Standardized by veterinary regulatory agencies worldwide, SCC serves as a non-invasive, cost-effective screening tool in dairy herd management and milk quality assessment. |
