NDF (Neutral Detergent Fiber)

Neutral Detergent Fiber (NDF) is a measure of plant cell wall components—specifically cellulose, hemicellulose, and lignin—that remain after removing soluble substances. It indicates the bulkiness and fill index of forage, influencing how much an animal can eat. High NDF levels often mean the feed is more fibrous and less digestible, limiting intake, while lower NDF suggests easier digestibility and potentially higher energy availability. NDF is a key factor in evaluating forage quality for livestock, helping determine how suitable and nutritious the feed is for animals' dietary needs.
