Acid detergent fiber insoluble protein (ADFIP) on the forage analysis identifies unavailable protein, including that lost to heat damage.
Fiber fractions consisting of neutral detergent fiber (NDF), acid detergent fiber (ADF), cellulose, and sulfuric acid lignin were estimated in a batch processor (Ankom Technology Corp., Fairport, NY) using reagents according to Van Soest and Robertson (1980).
If you buy hay with more than 35% acid detergent fiber, your goats will find it tough to eat and hard to digest.
The samples were analyzed for DM, ash, organic matter (OM), crude protein (CP) through the micro-Kjeldahl method [16], and for neutral detergent fiber (NDF) and acid detergent fiber through the method of Van Soest et al [17].
Acid detergent fiber was determined using the method of Goering and Van Soest (1970), adapted for the Ankom 200 Fiber Analyzer (Ankom Technology).
