“…The data conform with the results reported by Fritz et al (1947). The soybean flakes used in the study of Clandinin et al (1947) may have been the cause of the variation as indicated by the results of Fritz et al (1947) who showed that two commercial samples of soybean grits differed markedly in growth value. Another cause of difference in the results reported may be found in the growth period used by Clandinin et al (1947) who used growth during the second week as a criterion while the data of Fritz et al (1947) and in this paper were based on a longer growth period.…”

“…pressure for 4, 10, 15, 20, 25, and 30 minutes, respectively. The first was chosen as a negative control, the 4, 10, and 15 minute autoclaving periods as representative of samples containing a part of the natural trypsin inhibitor present in soybeans and within the heating period suggested by Clandinin et al (1947) as satisfactory, and the 20, 25, and 30 minute autoclaving periods as representative of samples containing no trypsin inhibitor and generally recognized as being an adequate heating period. These soybean oil meals were then incorporated into rations and fed to day-old chicks under controlled feed intake to six weeks of age.…”

FEW new energy sources have proved to be worth exploiting for the feeding of non-ruminants.Cereals and root crops remain the main sources of energy, with fibrous materials, whether in their native or processed state, playing a very small part. However, American feeders have recently begun to use low-grade fats, inedible by man, in poultry feeding.With protein concentrates more attention is being given to improving the methods of processing to obtain materials of higher nutritive value than to developing new products. Since many materials at the onset of processing have a high intrinsic nutritive value, the problem is to devise methods of processing that will minimize loss of this value in the by-product destined for animal feeding. In some cases, as in the production of white iish meal and soya-bean meal, processing requirements are well understood. In other cases little is known, or obstacles stand in the way of adopting superior processing methods.One of the commonest and most informative is the biological value (BV), essentially a measure of the nutritive value of absorbed nitrogen. Another is the gross protein value (GPV), which is a measure of the value of the protein in a concentrate for supplementing the proteins in mixtures of cereals and miller's offals.In Table I1 (p. 243) are set out the GPV ratings of a number of concentrates, most of which * Part I:
