Extract

Rumen microorganisms change feed protein characteristics and convert some feed protein to microbial protein. Determination of feed protein degradability coefficients and acid detergent insoluble nitrogen (ADIN) content is necessary for calculation of metabolisable protein (MP) content of feedstuffs. Absence of true information about these coefficients of native feedstuffs is a prime problem for diet formulation in Iran. The objective of this study was to determine the protein degradability coefficients of some native feedstuffs and compare them with AFRC (1995) data (the system now being used in Iran) in the feeding of lactating cows in terms of intake, milk yield and milk composition.
