It has been found that peanutmeal is not deficient in cystine, tryptophane or lysine, but may be in the light of investigations which appeared after the work had been completed, deficient in methionine. Coprameal is not deficient in cystine, while linseedmeal and soyabeanmeal are definitely deficient in cystine.en© 1938 ARC - Onderstepoort and Faculty of Veterinary Science.
