Alfalfa saponin extract was prepared from Du Puits leaf protein concentrate (LPC) and its effects on chick performance and plasma cholesterol level were investigated in two experiments. When the alfalfa saponin containing 41.8 mg/g of medicagenic acid was added at a level of 0.3% to the casein-amino acid diet, chick performance was not affected. The addition of 1.0% cholesterol significantly increased plasma total- and LDL-cholesterol levels, and in this case, the alfalfa saponin addition was effective in lowering these levels. While, chick performance was depressed when 0.3% alfalfa saponin was added to the alfalfa LPC diet containing 0.97 mg medicagenic acid per gram diet, and the adverse effect of saponin was alleviated by 1.0% dietary cholesterol addition. The alfalfa saponin lowered both total- and LDL-cholesterol levels in the plasma, irrespective of the cholesterol addition. HDL-cholesterol level was not affected by the alfalfa saponin in both experiments.
