The marked improvement in the apparent nutritive value of soybean protein after heating has long been recognized. The fundamental cause of this improvement has never been fully understood. Furthermore, commercial soybean oil meal varies considerably in nutritive value although heat treatment is common in most processing plants. Since heating is generally regarded as deleterious to the nutritive quality of protein, the following investigations of various treatments of soybean oil meal are of particular importance in developing a soybean or soybean oil meal of maximum and uniform nutritive value.

The Influence Of Whole Wheat, Bran And Shorts On Body Weight And Feather Growth In Chicks, F. E. Mussehl, C. W. Ackerson, M. J. Blish
The Influence Of Whole Wheat, Bran And Shorts On Body Weight And Feather Growth In Chicks, F. E. Mussehl, C. W. Ackerson, M. J. Blish
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The proteins of the entire wheat kernel and of the bran and shorts are apparently utilized with equal efficiency by growing chicks when used with a base of corn, barley, oats, meat scraps, fish meal, and soybean meal. The relatively higher protein levels of bran and shorts, as compared to ground wheat, should be considered by the poultry producer in deciding which product or products can be used with greatest economy. A good concentration of a feather-growth factor is found in wheat bran. Other common feedstuffs carry the same essential, and the amount of bran which should be used in …
