ANIMAL NUTRITION

IMPORTANCE OF CHEMISTRY AND PHYSIOLOGY.

In the nutrition of domestic animals, chemistry and physiology have made great advances, observed Dr. J. M. Swaine, ■ Director, Science Service, Dominion Department of Agriculturb, in a recent address to the Royal Society of Canada. With nutrition, as well as with disease, researches on animals and man are closely linked. The poorer classes of the Finnish population receive a large part of their vitamin supply in the winter time from milk, of which they consume relatively large quantities, states a recent report. The vitamin A content of the winter milk was found to be only about one-third as high as that of summer milk, when i cows were fed in the ordinary way. Finnish bio-chemists worked out the i following procedure:—Clover and lucerne, which could be frequently cropped. wore cut in the green stage and ensiled in a special way so that the carotene content was largely retained, and when this ensilage was fed lo cows it was found that even in winter the vitamin A content of the milk was as high as in summer milk.
