The nutritional values of Camelina sativa Crantz and Crambe abyssinica Hochst, two potential dietary protein sources, were compared to egg and casein by feeding the ether-extracted autoclaved meal of each cultivar as the sole source of protein in semipurified diets to young mice for 14 days. The dietary protein levels chosen were 8, 11, 14 and 17%. The crambe meals contained less crude fibre than the camelina meals. Only trace quantities of glucosinolates were found in camelina meal. Substantially higher levels of glucosinolates were found in the crambe meals and there was evidence of a small proportion of the glucosinolates having been hydrolyzed prior to assay. Weight gains, food intakes and protein efficiency ratios of mice fed camelina or crambe meal diets were consistantly lower than the responses of mice fed corresponding levels of egg or casein diets. Food intake increased as the level of camelina meal in the diet increased. It appears that growth depressing factors in both the camelina and crambe meals were significant. Effective removal or counteraction of the deleterious factors is necessary before the potential of the protein in these two meals can be exploited.

Camelina Seed

Camelina seed was ground, solvent-extracted, and fed at levels of 0, 5, 10, 15, 20 and 25% of the diet to weanling mice. Licorice (0 and 0.025%) was tested as a cross-treatment to modify flavor. Levels up to 10% resulted in no adverse effects on growth of mice but each increase in level beyond 10% resulted m a significant (P <.05) reduction in gains and feed intakes. Licorice was ineffective.In a second experiment 20 to 22% of camelina meal was fed m all diets. Raw meal was compared with dry-heated meal (12 hours, 135 °C), autoclaved meal (15 min, 1.2 kg/cm2), steam-stripped (2 hours, 110 °C) and a casein–methionine–supplemented control diet. In each case, four myrosinase-source supplements were added: nil, crambe seed, rapeseed, and camelina seed (Crambe abyssinica Hochst., Brassica napus L., and Cameline sativa Crantz).Destruction of myrosinase by any method of heating resulted in significantly better feeding value of camelina meal, but steam stripping was superior to dry heating or autoclaving.It was concluded that camelina meal is probably superior to rapeseed and crambe meals, in that more than 10% of raw meal is tolerated in the diet before growth depression occurs. Near maximum growth was obtained with myrosinase-free diets containing about 20% meal. Growth depression that occurred at the higher levels of intake exceeded that which could be accounted for by the content of volatile isothiocyanates.

Faba Beans

Four castrated pigs, each fitted with a re-entrant cannula in the terminal ileum, were used to study digestion in the small intestine. A nitrogen-free diet was used for the estimation of metabolic nitrogen and amino acids. Faba beans, as the sole source of dietary protein, were used raw or after autoclaving for 30 or 60 min. The four diets were fed to the pigs in a 4 × 4 latin square experiment. The pigs were fed each diet for 6 days prior to a 24-hr collection of total ileal contents. Autoclaving of faba beans had no significant effect on digestibility of dry matter, gross energy, nitrogen and individual amino acids except arginine, which was significantly increased. The intestinal uptake of arginine was the highest and of cystine the lowest in all faba bean diets. It was concluded that autoclaving faba beans had no beneficial effect on the digestion of nutrients in the small intestine of the pig.
