Abstract:
By means of the paired feeding method, it has been shown that the addition of cystine to lucerne significantly enhances the growth promoting properties of the latter, and that when peanutmeal is supplemented by oatmeal the resulting protein mixture is superior to that of peanutmeal alone.
Nitrogen metabolism studies conducted on the same rations showed that the incorporation of •20 per cent. cystine in a lucerne ration definitely increased the biological value of lucerne, that no supplementation exists between peanutmeal and lucernemeal, and
that supplementation occurs between peanutmeal and oatmeal.
