Nutritive Value of Soya Bean Meal as Measured by Chemical and Physical Methods

Abstract

INTRODUCTIONTHE Lund and Sandström fractionation technique (1943) separated proteins of plant origin into five fractions. These are the water-soluble or the albumins, the saline-soluble or the globulins, the alcohol-soluble or the prolamines, the alkali-soluble or the glutelins and the non-soluble or the residual proteins. Evans and St. John (1945) reported correlation coefficients of 0.928 and −0.788 between the grams gain in weight of chicks per gram of supplementary protein consumed and the glutelin fraction and the residual proteins of soya bean meal, respectively. For the estimation of gross protein value of plant proteins by the Lund-Sandström technique, Anwar (1962a) reported the glutelin fraction of groundnut meals to give the best indication of their nutritive value, while in the case of cottonseed meals it was the globulin fraction which was more reliable.Balloun et al. (1953), in studies on the laboratory estimation of the nutritive value of soya bean meal, …
