Add to sauerkraut juice, tomato juice, and other juices that are good for what ails you grass juice. Drs. C. A. Elvehjem and E. B. Hart of the University of Wisconsin have discovered that the growth-promoting growth-promoting properties of milk can be appreciably enhanced by the addition of grass juice. Juice squeezed out of lawn clippings was added to the daily milk ration of young rats, causing them to gain weight much more rapidly than "control" rats that got just plain milk. Liver and brain tissue were also found able to promote growth when added to winter milk. This finding, if it proves applicable applica-ble to human nutrition, may point to the desirability of fortifying winter win-ter milk with materials containing the growth factor which it lacks. . Growth Factor Unknown. Such additions will not be necessary neces-sary with milk produced in summer, sum-mer, for cows having access to pasture give a product which is potent in promoting growth. Just what is the nature of the growth factor with which winter milk is inadequately supplied is not definitely known. The fact that brain and liver apparently contain considerable amounts of it suggests it may be vitamin B4, but this is not certain. The fact that the search for materials ma-terials to improve the quality of winter milk resulted in failure with many substances narrows the possibilities pos-sibilities of what the unknown growth factor may be. Vitamins B and B2 proved of no value in trials at the University of Wisconsin. Since carotene, cod liver oil, orange juice, and irradiation irradia-tion all failed to improve milk as far as the growth factor is concerned, con-cerned, evidently it is not A, C, or D. |
