In the oil of seeds of the tropical legume Psophocarpus tetragonolobus (winged bean) of Vietnamese provenance the content of higher fatty acids was determined. Compared with soybean and peanut oils, winged bean oil contains more acids with a long carbon chain C20-C24. In order to verify the nutritive values of winged bean oil, an experiment on broilers was carried out. An addition of 50 g/kg oil into the BR-2 feed mixture enhanced the body mass gains significantly (P0.05) in comparison with the control. The effect of winged bean oil on weight gain, however, was not so significant as of fodder fat (P0.01). The differences between the above-mentioned treatments were still statistically non significant. Furthermore, the most convenient conditions of extraction of the oil from seeds, the solvent/cake ratio and the extraction time were verified.
