Extract

The extent of uncertainties associated with most of the existing protein evaluation systems for ruminants necessitates the need for some alternative investigations. Recently Newbold and Rust (1990) have demonstrated a close relationship between rumen proteolysis and protein fractions of soybean meal. Such relationship may be helpful in describing different feed proteins in terms of their ability to supply amino acid N to ruminant tissues. Present experiments were, therefore, conducted to examine the feasibility of using parameters such as protein size, type and structure, determined by solubility and electrophoresis for the evaluation of a variety of feed proteins.
