An Adaptation of the Paired-feeding Method for the Determination of the Supplementary Value of Proteins

Nutritive value of lucerne-leaf proteins

“…Smuts & Marais (1938) did not find any supplementary relationship between groundnut meal and lucerne meal (the latter presumably including both leaf and stem). The experiments of Haag (1934) appear to indicate that the proteins of lucerneleaf meal and wheat bran supplement each other. Table 4 shows that even mild autoclaving will impair the quality of lucerne proteins.…”

“…The proteins of lucerne leaf have been reported (Haag, 1934) to possess a low protein efficiency ratio (0.40 and 0.69 when given at levels of I 1.0 and I 1-7 yo protein respectively). I n my experiments, in which the protein level was 6y0, the ratio observed was higher (1.09).…”
