PREFER FLINT CORN
 ID AMERICAN BRAND
European Countries Buy Argen- tine Product Instead Of From U. s.


 Washington. Dec. 29.-In an e.for to determine the reason for the pref
 erence of European countries for Ar,
 gentine or flint corn to the cor,
 produced in the United States, tn,
 department of agriculture through it.
 bureau of chemistry is undertaking
 an extensive investigation. Accord.
 ing to w. c. Campbell. acting chiei
 chemist, the investigation will be con.
 ducted through laboratory on cror l, chemistry, recently esAblished, which ! will determine If tLere are any fun ] damental chemic<t differences in the composition of flint or hard corn and
 the dent corn largely produced in the United States.
 The laboratory will undertake
 studies on the composition of agri-
 cultural crops in a fundamental way.
 Additional work will be carried on
 concerning the influence of environ
 ment on the chemical composition of
 crops, including certain features of
 fertilization, such as the relation of chemical composition and food value of crops to the time of fertilizer ap- plication.' Previous work has been directed chiefly toward the quantity viewpoint. The new work will be directed to quality.
 It Is known. for instance,' says Mir. Campbell, that the application of certain fertilizer to g crop like corn will increase the yield quantt- tatively, However. practically noth- ing is known about quality relations: that is, whether the proteins, vita- mins, or mineral components of the corn fertilized in such way are bet triton than those of unfertilized corn. varietal differences will be studied from chemical standpoint
 "One of the moYt important re- searches now under way is that upon vegetable proteins. Inasmuch as ni- trogen is an essential part of animal tissues and the animal can obtain this necessary nitrogen only In the form of protein in its food it is obvious that this class of feeds is of prime importance. This research involves the very existence of all animals and is inseparably connected with the field of nutrition.
 Until quite recently one kind of protein in diet was considered as good as another. Today we know | that one protein differs from an- other protein in certain Fundamental | constituents called amino acids, of | which all proteins are composed. | Some of the amino acids are abso- lutely. essential for nutrition, for f without them animals will not grow, but will soon fail and die, The pro- tein in corn Is deficient in two essen- tial amino acids tryptophane and lysine. A young animal on a diet having it's sole sn...-ce of protein de- rived from whole cor,s will not grow and develop properly. However, if the protein in corn is supplemented by the addition in the right propor- tion of certain other proteins the protein of the mixture will then be adequate for normal growth. It is essential not only to know whether In themselves they are adequate for the needs of the animal but also to know when they are deficient, what other proteins, and in what propor- ton, must be added to supplement the deficiency. The percentage of nitrogen alone cannot therefore any longer be regarded as an index of the protein value of a feeding stuff.
 "The amino acids of the proteins of several agricultural products have been separated and studied. with the result that it is now possible to sup plement such basic feeding stuffs as ,orn with small quantities of other leeds, such as peanut meal, soy-bean neal, and cocoanut press cake, which contain the very amino acids corn acks, thus making a feed that will { ,upply all the amino acids necessary or growth. The practical results of his should be a greater and more profitable utilization of our largest cereal crop-corn."
 Work now in progress includes in- of the protein of wheat ,ran, in which method has been de- -eloped by which over 90 per cent. of he total protein in bran may be ex- racted of cotton seed of peanuts, of antaloup seed, of soy-beans, of palm .ernel meal and of lentils. Research n the protein in tomato seed, over 1000 tons of which are discarded an- ually as a by-product of the tomato ulping industry, show that by utili- ation of this by-product for feed az purposes the conservation of a aluable feed can be accomplished
