Abstract:
By means of the nitrogen balance-sheet method a biological value of 55 for soyabeans and 78 for linseedmeal at approximately 8 per cent. level has been obtained. Utilizing the same method, and substituting an equivalent amount of soyabean nitrogen by .20 per cent. cystine it was found that cystine supplemented soyabean protein effectively and increased the utilization of its nitrogen by 19 per cent.
