Rumen proteolysis of constituent proteins of soyabean meal

Extract
Many feedstuffs consist of a variety of proteins which, differing in size and structure, may undergo proteolysis in the rumen at different rates. The conventional use of single, constant coefficients to describe the proportion of protein degraded in the rumen (e.g. 0.65 for soyabean meal) may, therefore, be inappropriate. Soyabeans contain two major storage proteins, β-conglycinin and glycinin. Two experiments were conducted to assess differences in rate of proteolysis between α and β sub-units of β-conglycinin (molecular weight approximately 66kD and 56kD, respectively) and acidic and basic sub-units of glycinin (approximately 36kD and 23kD, respectively).
