Digestibility of feed

Common Terms Used in Animal Feeding and Nutrition

Digestibility is defined as the fraction of a nutrient ingested that is digested and absorbed by the animal. Animals are fed the test diets for a period of time for several days and fecal samples are collected and are analyzed for excreted nutrient loss. See more Evaluation of the feed is more precise if expressed in terms of the digestibility of each of the nutrients rather than its total content in the feed. Therefore, knowledge … See more Although not a true measurement, apparent digestibility is used widely. Monitoring feed intake and fecal collection can be time consuming, laborious, and … See more The true digestibility of a nutrient is the proportion of the dietary intake that is absorbed from the GI tract, excluding endogenous contribution.
