The green crop fractionation was planned to use feedstuff efficiently by separating plant materials into two fractions; water-soluble protein fraction (leaf protein concentrate; LPC) as protein source for monogastric animals and fibrous residue as energy source for ruminants. However, feeding LPC prepared from alfalfa severely depressed chick growth rate. This adverse effect was attributed to the anorexia due to alfalfa saponins. The bitter taste of saponins was considered as factor suppressing the appetite, but a series of experiments has suggested that saponins impair physiological functions of animals by interfering with membrane sterols. The nutritive value of alfalfa LPC was improved by adding cholesterol, but blood cholesterol concentrations were not elevated. Alfalfa saponins partly accounted for the hypocholesterolermic effect of the LPC.
