Popis: ALTHOUGH the superior value of properly heated soybean oil meal over raw or improperly heated meal for the nutrition of the chick has been recognized since the work of Wilgus et al. (1936) and of Hayward et al. (1937), a precise definition of properly heated soybean oil meal has not been attained. In a recent publication, Clandinin et al. (1947) presented data indicating that soybean flakes autoclaved at 15 lbs. pressure for four to fifteen minutes gave the most satisfactory gains in chicks. These results were contradicted by the findings of Fritz, Kramke and Reed (1947) who reported from tests on turkey poults that the best biological value was obtained when ground raw soybeans were autoclaved at 15 lbs. pressure for 20 to 30 minutes. Westfall and Hauge (1947) stated that the growth efficiency of soybean flour for rats was inversely related to the quantity of trypsin inhibitor present in . . .
